Astronomy Daily: Space News Updates

Artemis II, Comet MAPS, and Mercury: Your Space Week Just Got Very Busy It's Day 3 of the Artemis II mission, a sungrazer comet is emerging from the solar corona, an Atlas V just set a payload record, and Mercury is at its best of the year. Here's everything you need to know from today's episode of Astronomy Daily. Artemis II Flight Day 3: Orion Doesn't Even Need a Course Correction Four humans are on their way to the Moon, and everything is going better than planned. Flight controllers cancelled the first of three scheduled trajectory correction burns today — Orion is already on such a precise path that the burn simply wasn't needed. As Howard Hu, NASA's Orion program manager, noted, this reflects exceptional navigation performance throughout the mission. The crew — Commander Reid Wiseman, Pilot Victor Glover, Mission Specialist Christina Koch, and CSA astronaut Jeremy Hansen — spent Day 3 on medical readiness drills, practising CPR in weightlessness and checking out the spacecraft's medical equipment. They also successfully tested Orion's optical communications system, transmitting HD video back to Earth from deep space. On Monday, April 6th, Orion will swing around the lunar far side at its closest approach — briefly out of radio contact with Earth — and at the mission's farthest point will travel 252,757 miles from home. That breaks the human spaceflight distance record set by Apollo 13 in 1970. Fifty-six years. We're finally going further. Comet MAPS: The Solar Plunge Is Done — Now Comes the Wait At 14:22 UTC on April 4th, Comet C/2026 A1 (MAPS) reached perihelion — passing just 161,000 kilometres from the surface of the Sun, skimming through the lower solar corona. Whether it survived that encounter is still being determined from spacecraft imagery, as the comet remains in the Sun's glare for ground-based observers. If MAPS emerges intact, the Southern Hemisphere viewing window opens April 6th to 10th. Look west after sunset, low on the horizon, near Venus. Brightness predictions range from magnitude -5 (comparable to Venus) to extraordinary scenarios even brighter. Even a nucleus breakup could leave a spectacular dust tail — what's known as a 'headless wonder.' Either way, this story is not over. Atlas V Sets a Record: 29 Amazon Leo Satellites, Heaviest Payload Ever At 1:45 a.m. Eastern Time on April 4th, a ULA Atlas V 551 lifted off from Cape Canaveral carrying 29 Amazon Leo satellites — the heaviest payload in the rocket's 102-mission history. Mission LA-05 continues Amazon's build-out of its 3,200-satellite internet constellation (formerly Project Kuiper), with around 241 satellites now on orbit. Amazon faces an FCC deadline to have half its constellation operational by July 2026. Blue Ghost Challenges a Fundamental View of the Moon New data from Firefly Aerospace's Blue Ghost lander — which operated on the lunar surface for two weeks in March 2025 — is shaking up decades of lunar science. Scientists expected Blue Ghost's landing site at Mare Crisium, well outside the Moon's 'hot zone,' to show significantly cooler interior temperatures than Apollo landing sites. It didn't. The near-side/far-side temperature divide may be far less pronounced than previously thought, suggesting heat-producing elements are more widely distributed beneath the surface. 'We may have to abandon that binary,' said principal investigator Seiichi Nagihara. Pulsars Broadcast Further Than Anyone Knew — With Australian Science Behind the Discovery A study led by Professor Michael Kramer (Max Planck Institute) and Dr Simon Johnston (CSIRO) has found that about one third of millisecond pulsars emit radio waves from two completely separate regions — including a distant zone at the very edge of their magnetic reach called the current sheet. This overturns decades of received wisdom and suggests pulsars should be detectable from a wider range of directions than previously thought — with implications for gravitational wave detection using pulsar timing arrays. Mercury Is at Its Best All Year — And Southern Hemisphere Skywatchers Win Mercury reached greatest western elongation on April 3rd — the year's best opportunity to see the innermost planet. From Australia and New Zealand, this is specifically the best morning apparition of Mercury in 2026. Look east about 30-40 minutes before sunrise for a steady point of light at around magnitude 0.4, just above Mars. Through binoculars or a small telescope, Mercury is currently showing a half-illuminated quarter phase. And on April 18th, Mercury, Saturn, Mars, and Neptune will gather in a tight morning-sky cluster — three of them visible to the naked eye.Become a supporter of this podcast: https://www.spreaker.com/podcast/astronomy-daily-space-news-updates--5648921/support.Sponsor Details:Ensure your online privacy by using NordVPN.

Astronomy Daily Season 5, Episode 80 — Friday, April 3, 2026 It's Day 2 of the Artemis II mission and the crew is on their way to the Moon after a perfect translunar injection burn. We've also got a comet about to face perihelion, a dark matter mystery deepening, stunning new JWST images, and the escalating fight over the future of our night skies. In today's episode: 🚀 ARTEMIS II — TRANSLUNAR INJECTION BURN: The Orion spacecraft successfully completed its TLI burn on April 2, sending four astronauts toward the Moon for the first time since Apollo 17 in 1972. Canadian astronaut Jeremy Hansen delivered one of the quotes of the year from orbit. 🚽 ARTEMIS II — THE LUNAR LOO: Hours after launch, Orion's toilet malfunctioned. Christina Koch fixed it. This is why test flights exist. ☄️ SUNGRAZER COMET C/2026 A1 (MAPS): Tomorrow, this Kreutz sungrazer passes 161,000 km from the Sun's surface. It could vaporise — or become the most spectacular comet since Ikeya-Seki. Southern Hemisphere watchers: eyes on the western horizon from April 6. 🌌 DARK MATTER-FREE GALAXIES: Yale astronomers have confirmed a third galaxy with essentially no dark matter — NGC 1052-DF9. The 'Bullet Dwarf' collision theory is gaining powerful evidence. 🌟 JWST + W51: The James Webb Space Telescope has revealed hidden young stars in the W51 star-forming region, piercing dust clouds that have blocked our view for decades. ⚠️ NIGHT SKY UNDER THREAT: Reflect Orbital's orbital mirror satellite launches this month.

Episode S05E75 — Saturday, 28 March 2026 | astronomydaily.io | @AstroDailyPod 🚀 Story 1: Artemis II Crew Arrives at Kennedy Space Center The four-person crew of NASA's Artemis II mission — Commander Reid Wiseman, Pilot Victor Glover, Mission Specialist Christina Koch (NASA), and Mission Specialist Jeremy Hansen (CSA) — arrived at Kennedy Space Center on Friday, March 27, 2026, ahead of a planned April 1 launch. The 10-day mission will fly the crew around the Moon and back to Earth — the first crewed lunar mission since Apollo 17 in 1972. Launch window: 6:24 PM EDT, April 1–6, 2026. Sources: NASA.gov, Space.com, AP, Orlando Sentinel ☄️ Story 2: Hubble Detects First-Ever Spin Reversal of a Comet A new study in The Astronomical Journal reveals that comet 41P/Tuttle-Giacobini-Kresák reversed its direction of rotation — a first in observational astronomy. Gas jets acting as thrusters slowed the comet's spin and flipped it into a new direction. The comet's nucleus measures just 1 km across. Researchers warn the rapid new spin could lead to the comet's disintegration. Source: NASA Science / Space Telescope Science Institute, March 26, 2026 🌑 Story 3: LIGO Signal May Be a Primordial Black Hole A November 2025 LIGO detection of a gravitational wave signal from an object with less than one solar mass — impossible through stellar evolution — may be evidence of a primordial black hole formed in the Big Bang's first moments. A new University of Miami study in The Astrophysical Journal finds the detection consistent with primordial black hole models and suggests these objects could help explain dark matter. Source: Universe Today / University of Miami, March 27, 2026 ⭐ Story 4: IXPE Delivers New Portrait of Oldest-Known Supernova NASA's IXPE (Imaging X-ray Polarimetry Explorer) has produced a new X-ray image of supernova remnant RCW 86 (SN 185) — the oldest recorded supernova, first observed by Chinese astronomers in 185 AD. Combined with Chandra and XMM-Newton data, the image reveals the remnant's expansion has slowed at the edge of a low-density cavity, producing a reflected shock. Source: NASA / Phys.org, March 25–27, 2026 🏥 Story 5: Mike Fincke Speaks About His ISS Medical Emergency NASA astronaut Mike Fincke has given his first detailed account of the January 7, 2026 medical event that led to the first-ever medical evacuation from the International Space Station. In an AP interview, Fincke revealed he lost the ability to speak for approximately 20 minutes while eating dinner. Doctors have ruled out a heart attack but the cause remains unknown. The incident ended Crew-11's mission early, returning Fincke, Zena Cardman, Kimiya Yui, and Oleg Platonov to Earth on January 15. Source: Associated Press / Phys.org, March 27, 2026 ☀️ Story 6: Solar Activity — AR4403 Flares, Possible CME March 29 Sunspot region AR4403, which rotated into view on March 26, produced an M3.9 solar flare causing a minor radio blackout over the Indian Ocean. Conditions are quiet on March 28, but space weather forecasters expect a co-rotating interaction region and coronal hole high-speed stream to arrive March 29, bringing unsettled geomagnetic conditions and possible aurora visibility at mid-latitudes. Southern Hemisphere observers in Australia and New Zealand should watch Sunday–Monday nights.

Wednesday, March 25, 2026 In today's episode of Astronomy Daily, Anna and Avery cover six major stories from the last 24 hours in space and astronomy — including two landmark NASA announcements that could reshape the future of human space exploration. Story 1: NASA Cancels Lunar Gateway — Pivots to $20 Billion Moon Base NASA Administrator Jared Isaacman announced at the agency's 'Ignition Day' event that the Lunar Gateway orbital space station has been paused, with resources redirected toward a phased $20 billion base on the lunar surface. The three-phase plan runs from 2026 to beyond 2032 and involves international partners including JAXA, the Italian Space Agency, and the Canadian Space Agency. Source: https://www.space.com/space-exploration/artemis/nasas-lunar-gateway-space-station-is-out-moon-bases-are-in Story 2: NASA's SR-1 Freedom — The First Nuclear-Powered Interplanetary Spacecraft Also announced at Ignition Day, Space Reactor-1 Freedom is planned for a December 2028 launch to Mars. It will use Nuclear Electric Propulsion and carry the Skyfall payload — three Ingenuity-class helicopters designed to scout future human landing sites and map subsurface water ice. Source: https://www.space.com/astronomy/mars/nasas-1st-nuclear-powered-interplanetary-spacecraft-will-send-skyfall-helicopters-to-mars-in-2028 Story 3: Two Planets Forming Around Infant Star WISPIT 2 Astronomers using the ESO's Very Large Telescope have directly imaged two gas giant planets forming around the 5.4-million-year-old star WISPIT 2, located 437 light-years away in Aquila. The system is described as a mirror of our early solar system, with potential for more planets yet to be discovered. Published in The Astrophysical Journal Letters.

The images reveal the nebula's continued expansion — the still-evolving remnant of a supernova first observed by astronomers in 1054 AD. Source: https://www.space.com/astronomy/hubble-revisits-a-cosmic-crab-after-25-years-space-photo-of-the-day-for-march-23-2026 Story 5: Fiber-Optic Cables Could Detect Moonquakes Two new studies from Los Alamos National Laboratory suggest that fiber-optic cables deployed directly on the lunar surface could detect moonquakes using Distributed Acoustic Sensing (DAS). The technique could replace expensive individual seismometers, with a single cable acting as thousands of sensors across hundreds of kilometres of lunar terrain. Source: https://www.space.com/astronomy/moon/future-artemis-missions-could-use-fiber-optic-cables-to-monitor-moonquakes Story 6: Rocket Lab 'Daughter of the Stars' — Europe's First Celeste Navigation Satellites Rocket Lab's Electron rocket launched the first two satellites for ESA's Celeste LEO-PNT constellation from Māhia, New Zealand on March 25. The mission is ESA's first foray into low-Earth orbit navigation, designed to complement and strengthen Europe's Galileo system. The constellation is named after Maria Celeste, daughter of Galileo Galilei.

The crew of Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen will fly a 10-day free-return trajectory around the Moon aboard the Orion spacecraft on the SLS rocket from Kennedy Space Center. The six-day launch window runs April 1–6. Meanwhile, a new analysis suggests the mission could face elevated solar superflare risk, though NASA is proceeding after a successful Flight Readiness Review.

The Australian Bureau of Meteorology issued a severe storm warning for March 23. Conditions are easing on March 24 (Kp 3–4) but some aurora activity may continue. March is historically the best month for auroras due to the equinox effect, and with Solar Cycle 25 at its peak, scientists say this could be the best aurora viewing period until the mid-2030s.

TOI-561 b — an ultra-hot super-Earth about twice Earth's mass, orbiting its star every 10.56 hours — was expected to be a bare rock. Instead, JWST measured a dayside temperature far cooler than a bare rock would produce, indicating a thick atmosphere redistributing heat above a global magma ocean. The findings were published in The Astrophysical Journal Letters.

A Brown University-led team found volcanic material from the Taurus-Littrow region is strongly depleted in sulfur-33 — unlike anything found on Earth. Possible explanations include ancient lunar atmospheric chemistry or a legacy of the Theia impact that formed the Moon. Published in the Journal of Geophysical Research: Planets.

Astronomy Daily — Season 5, Episode 70 Monday, March 23, 2026 In today's episode, Anna and Avery cover six stories spanning a live European rocket launch attempt, a sixty-year-old NASA emergency brought back to life through newly surfaced photographs, a cosmic explosion caught only by its echo, the fight to preserve the night sky, a supply run to the ISS with an unexpected complication, and a first-of-its-kind discovery involving brown dwarf stars. Story 1: Europe's Spectrum Rocket — Bid for Orbit Today Isar Aerospace's Spectrum rocket is attempting its second test flight today — its qualification mission for ESA's European Launcher Challenge. Launching from Andøya Spaceport in Norway, the mission carries five CubeSats and one experiment from European universities and companies, all supported by ESA's Boost! program. If successful, it would mark a landmark moment for European sovereign access to space. Source: ESA — Spectrum's Qualifying Second Launch Story 2: Neil Armstrong — The Gemini 8 Emergency Sixty years ago this month, Neil Armstrong and David Scott survived one of NASA's most dangerous pre-Apollo emergencies aboard Gemini 8. A spacecraft malfunction sent the capsule into an uncontrolled spin reaching one revolution per second. Never-before-seen photographs of Armstrong's recovery have been donated to the Armstrong Air and Space Museum in Wapakoneta, Ohio. Source: Phys.org — Space News Story 3: Astronomers Catch the Echo of a Billion-Sun Explosion Using the ASKAP radio telescope in Western Australia, astronomers identified ASKAP J005512-255834 — a radio signal representing the most convincing "orphan afterglow" of a gamma-ray burst ever detected. The original explosion went unseen because its jet wasn't aimed at Earth, but the lingering radio echo has been detectable for over 1,000 days. Research published in The Astrophysical Journal. Source: The Conversation — A Cosmic Explosion With the Force of a Billion Suns Story 4: The Fight to Save the Night Sky The Royal Astronomical Society, ESA, and the International Astronomical Union have filed formal objections to the FCC over two proposed satellite constellations: SpaceX's application for up to one million orbiting AI data centre satellites, and Reflect Orbital's proposal for 50,000 space mirrors each four times brighter than the full Moon. Experts warn the proposals could permanently transform humanity's view of the night sky.

Today on Astronomy Daily: NASA's Artemis II moon rocket has arrived at Launch Pad 39B at Kennedy Space Center, with a launch target of April 1st — the first crewed mission beyond Earth orbit in over 53 years. Plus: astronomers have discovered the first-ever mass-transferring brown dwarf binary; Hubble accidentally caught a comet disintegrating in real time; 15 new moons have been confirmed around Jupiter and Saturn; our Moon is accumulating over 100 metric tons of human-made debris; and a dramatic spacecraft double-header — ESA's Proba-3 has been recovered from a month-long blackout, while NASA's MAVEN Mars orbiter remains missing after more than three months of silence. Story 1: Artemis II Arrives at Launch Pad 39B NASA's Artemis II SLS rocket and Orion spacecraft completed an 11-hour overnight journey to Launch Pad 39B on March 20, 2026. Launch is targeted for no earlier than April 1. The crew — Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen — will fly a 10-day free-return trajectory around the Moon, making this the first crewed deep-space mission since Apollo 17 in December 1972. Source: https://www.nasa.gov/blogs/missions/2026/03/20/nasas-artemis-ii-rocket-arrives-at-launch-pad-39b/ Story 2: First Mass-Transferring Brown Dwarf Binary Researchers at Caltech have identified ZTF J1239+8347, a brown dwarf binary system with an orbital period of just 57.41 minutes in which one brown dwarf is actively pulling material from its companion — a first for this class of objects. The system, only ~1,000 light-years away, is a prime candidate for JWST follow-up observations. Published in The Astrophysical Journal Letters. Source: https://www.universetoday.com/articles/this-pair-of-brown-dwarfs-cant-get-enough-of-each-other Story 3: Hubble Catches Comet C/2025 K1 Breaking Apart In a remarkable stroke of luck, NASA's Hubble Space Telescope captured comet C/2025 K1 (ATLAS) fragmenting into at least four pieces over three consecutive days in November 2025. The comet was not the original target of the observation. The findings, published in Icarus, reveal the comet is unusually carbon-depleted and raise new questions about the delay between fragmentation and visible brightening. Source: https://science.nasa.gov/missions/hubble/nasas-hubble-unexpectedly-catches-comet-breaking-up/ Story 4: 15 New Moons Confirmed for Jupiter and Saturn The Minor Planet Center announced on March 16, 2026 that four new moons have been confirmed around Jupiter (bringing its total to 101) and 11 new moons around Saturn (bringing its total to 285). All are small irregular moons, discovered by combining archival telescope data with new observations. With the Vera C. Rubin Observatory now operational, further discoveries are expected. Source: https://earthsky.org/space/more-moons-for-jupiter-and-saturn-total-satellite-discoveries/ Story 5: Human Debris on the Moon — Over 100 Metric Tons and Counting More than 100 metric tons of human-made objects now litter the lunar surface — spacecraft hardware, scientific instruments, and even waste from Apollo missions. With a wave of crewed and commercial lunar missions approaching under Artemis and beyond, space policy researchers are urging the development of international agreements to protect scientifically sensitive lunar sites before they are damaged or contaminated by human activity. Source: https://www.universetoday.com — lunar debris policy Story 6: MAVEN Still Missing / Proba-3 Recovered NASA's MAVEN Mars orbiter, lost since December 6, 2025, remains uncontacted despite three months of recovery efforts using the Deep Space Network, Green Bank Observatory, and the Curiosity rover. An anomaly review board is assessing options. Meanwhile, ESA's Proba-3 coronagraph spacecraft — silent since February 14 after a power failure — has been successfully recovered after engineers exploited a brief window when the tumbling spacecraft's solar panels briefly faced the Sun.

It's the first day of astronomical spring — and the universe is celebrating in style. On today's Astronomy Daily, Anna and Avery cover a triple CME solar storm with aurora potential reaching as far south as Illinois, explain why the vernal equinox amplifies aurora activity, report on the ongoing meteorite hunt following Tuesday's spectacular Ohio fireball, reveal an extraordinary 14-billion-year-old star that carries the chemical fingerprints of the universe's very first stars, bring a happy update on Europe's Proba-3 solar science satellite which has ended a month of silence, and explain how X-ray CT scans of returned asteroid samples finally cracked one of Bennu's longest-standing mysteries. Stories in This Episode 1. Triple CME Strike + Equinox Aurora Alert Three coronal mass ejections (CMEs) are currently en route to Earth, with the first arriving today. Forecasters predict G2 (moderate) to G3 (strong) geomagnetic storm conditions, potentially bringing auroras as far south as Illinois. The timing coincides with the vernal equinox — historically one of the best aurora windows of the year due to the Russell-McPherron effect. 2. The Vernal Equinox — Today! The 2026 March equinox arrived today at 14:46 UTC, marking the astronomical start of spring in the Northern Hemisphere (and autumn in the Southern). Tonight, a thin crescent Moon appears alongside Venus in the west-southwest sky. 3. Ohio Fireball — Meteorite Hunt Underway On St. Patrick's Day (March 17), a seven-ton asteroid exploded over northeast Ohio with the force of 250 tons of TNT. NASA confirmed meteorites landed near Medina County, and hunters from across the US have already found fragments in the Sharon Center area. 4. Ancient 'Cosmic Fossil' Star PicII-503 Astronomers have discovered PicII-503, a second-generation star in the Pictor II dwarf galaxy with only 1/40,000th of the Sun's iron — the lowest ever measured outside the Milky Way. Its extraordinary carbon-to-iron ratio links it to mysterious carbon-enhanced metal-poor stars scattered across our galaxy's halo, solving a long-standing stellar mystery. Published in Nature Astronomy by Anirudh Chiti (Stanford) et al. 5. Proba-3 Phones Home — 'A Great Relief!' ESA confirmed on March 19 that its Proba-3 Coronagraph satellite — silent since mid-February after an anomaly caused it to lose attitude control — has reestablished contact via the Villafranca ground station. The spacecraft is in safe mode, solar-powered, and undergoing health checks before science operations can resume. 6. NASA Cracks Bennu's Boulder Mystery X-ray CT scans of returned OSIRIS-REx samples reveal Bennu's boulders are riddled with internal crack networks — the missing piece explaining the asteroid's puzzling low thermal inertia. Published in Nature Communications. The findings will improve asteroid characterisation from Earth-based telescopes globally.

A massive day in space as NASA's Artemis II moon rocket heads to the launchpad tonight, NASA and China both conduct spacewalks, CERN announces a brand-new particle, and astronomers reveal a nearby galaxy has been hiding the aftermath of a cosmic collision. Episode Highlights 🚀 Story 1: Artemis II Rollout — The Moon Rocket Heads to the Pad Tonight NASA is rolling the Artemis II Space Launch System and Orion spacecraft to Launch Pad 39B tonight (March 19), targeting an 8 p.m. EDT start for the slow 4-mile crawler journey. The April 1 launch window remains firmly on track. Crew members Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen have entered quarantine — making history as the first crew to venture to the vicinity of the Moon since 1972. Source: NASA Blogs / Space.com 👨‍🚀 Story 2: Dual Spacewalk Day — ISS & Tiangong Both Suit Up NASA astronauts Jessica Meir and Chris Williams completed U.S. Spacewalk 94 on March 18, spending 7 hours and 2 minutes preparing the ISS for a new roll-out solar array. Meanwhile on March 16, Shenzhou 21 commander Zhang Lu tied the Chinese EVA record with his sixth career spacewalk alongside crewmate Wu Fei outside China's Tiangong station. Sources: NASA / Space.com ⚛️ Story 3: CERN's LHCb Discovers New Doubly Charmed Particle The LHCb experiment at CERN announced the first discovery made by its upgraded detector: the Xi-cc-plus baryon, a proton-like particle containing two charm quarks and one down quark, making it roughly four times heavier than a proton. Detected at 7-sigma significance, it settles a two-decade-old scientific dispute and is the 80th particle discovered by LHCb. Source: CERN / Universe Today 🌌 Story 4: Small Magellanic Cloud Caught Mid-Transformation University of Arizona astronomers have confirmed that the Small Magellanic Cloud — one of the Milky Way's closest galactic neighbours — collided directly with the Large Magellanic Cloud a few hundred million years ago and is still reeling from the impact. The finding upends decades of assumptions about the SMC's use as a benchmark for early universe galaxy studies. Source: The Astrophysical Journal / Sky & Telescope 🪐 Story 5: Exotrojans — Hunting Asteroid Companions Around Other Stars A new paper in The Astrophysical Journal by Jackson Taylor (West Virginia University) and colleagues pushes the search for exotrojans — asteroid co-orbital companions to exoplanets — into some of the most extreme environments yet studied, as the hunt continues for the first confirmed detection. Source: The Astrophysical Journal / Universe Today 📡 Story 6: SETI Rethink — Time to Broaden the Search A new paper argues that the decades-long focus on narrow radio and microwave bandwidths in the search for alien signals may be too limiting, and proposes broadening the electromagnetic search to a much wider range of the spectrum.

In today's episode of Astronomy Daily, Anna and Avery cover six remarkable stories spanning an interstellar farewell, a stunning pre-dawn sky show, a potential new Martian mineral, ghost particles from long-dead stars, a revolutionary new framework for detecting alien life, and the astonishing possibility of habitable moons drifting starless through the galaxy. Stories Covered in S05E64 1. 3I/ATLAS: The Interstellar Comet's Jupiter Farewell: Today marks the closest approach of interstellar comet 3I/ATLAS to Jupiter before it leaves our solar system forever. New ALMA data reveals the comet carries extraordinary levels of methanol — a chemical fingerprint from another solar system entirely. 2. Mercury, Mars & the Moon: Tonight and tomorrow morning, Mercury and Mars gather close to a crescent Moon in the pre-dawn sky. Southern Hemisphere observers have the best view. This week also brings the March equinox (March 20) and heightened aurora activity. 3. A New Mineral on Mars?: Scientists may have discovered a previously unknown mineral hidden in Mars's ancient sulfate deposits. Found by combining laboratory experiments with orbital spectroscopy, the potential discovery could shed new light on Mars's ancient watery past. 4. Ghost Particles from Dead Stars: Japan's upgraded Super-Kamiokande detector may detect the Diffuse Supernova Neutrino Background for the first time in 2026 — a faint signal from every supernova across cosmic history, including stars that exploded before Earth was born. 5. Life, But Not As We Know It: A new framework called Assembly Theory, published today in Universe Today, offers a way to detect alien life that bears no resemblance to life on Earth. Rather than searching for specific biosignature gases, it asks how complex the atmospheric chemistry is — and is designed for the upcoming Habitable Worlds Observatory. 6. Starless Moons: Moons orbiting free-floating planets — worlds ejected from their home solar systems — could sustain liquid water oceans for up to 4.3 billion years, powered by tidal heating and insulated by hydrogen atmospheres.

Our Sun turns out to have hitched a ride outward from the Milky Way's interior billions of years ago — and brought thousands of stellar companions with it. China has named a leading candidate for its first crewed Moon landing. Russia is dusting off the legacy of the legendary Soviet Venera programme with an ambitious 2036 return to Venus. NASA's nuclear-powered Titan drone is now being physically built. China's Mars sample return mission is constructing actual spacecraft. And in honour of Pi Day, we visit the exoplanet whose year lasts almost exactly 3.14 days. Story 1: The Sun Was Part of a Galactic Migration of Solar Twins A new study in Astronomy & Astrophysics by researchers at Tokyo Metropolitan University and the National Astronomical Observatory of Japan has built the largest-ever catalogue of solar twins — 6,594 Sun-like stars. Using ESA's Gaia satellite, they found a clustering of stars aged 4–6 billion years, suggesting the Sun migrated outward from the Milky Way's inner regions billions of years ago, possibly when the galactic bar was still forming and its 'corotation barrier' was weak enough to allow mass stellar movement. This migration may have placed Earth in a calmer, more life-friendly region of the Galaxy. • Journal: Astronomy & Astrophysics (March 2026) • Lead researchers: Daisuke Taniguchi (Tokyo Metropolitan University) & Takuji Tsujimoto (NAOJ) • Data source: ESA Gaia satellite — catalogue of ~2 billion stars • Key finding: Sun likely formed ~10,000 light-years closer to the Galactic Centre than its current position Story 2: China Eyes Rimae Bode for Its First Crewed Moon Landing A study published in Nature Astronomy (9 March 2026) proposes Rimae Bode — a volcanic region near Sinus Aestuum on the lunar near side — as a prime candidate for China's first crewed lunar landing, targeted for 2030. The site contains five distinct terrain types including pyroclastic deposits, mare basalts, rille systems and highland material. Researcher Jun Huang (China University of Geosciences, Wuhan) described it as a 'geological museum.' Four specific landing spots within the region have been proposed. • Journal: Nature Astronomy (March 2026) • Lead researcher: Jun Huang, China University of Geosciences, Wuhan • Site: Rimae Bode, near Sinus Aestuum, lunar near side • Oldest volcanic activity in region: ~3.2–3.7 billion years ago • China's crewed lunar landing target: 2030 Story 3: Russia Plans Venera-D Mission to Venus in 2036 Russia's First Deputy Prime Minister Denis Manturov confirmed on 10 March 2026 that Russia plans to launch the Venera-D mission — comprising a lander, atmospheric balloon, and orbiter — to Venus in 2036. The mission would extend the legacy of the Soviet Venera programme (1961–1983), which remains the only national programme to have successfully landed on Venus. Scientific goals include searching for microbial life in Venus's clouds and studying the planet's atmosphere. • Mission: Venera-D (lander + balloon + orbiter) • Planned launch: 2036 • Agency: Roscosmos • Heritage: Soviet Venera programme — 16 missions, 1961–1983 • Science goal: Search for biosignatures in Venusian cloud layers (48–60 km altitude) • Source: TASS, citing Razvedchik Journal interview with Denis Manturov Story 4: NASA Begins Building Dragonfly — Nuclear-Powered Drone for Titan NASA and Johns Hopkins Applied Physics Laboratory (APL) officially began integration and testing of the Dragonfly rotorcraft on 10 March 2026. The car-sized, nuclear-powered octocopter is designed to fly across the surface of Saturn's moon Titan, targeting a 2028 launch on a SpaceX Falcon Heavy and arriving at Titan in 2034. It will explore diverse terrain including organic dunes and the Selk impact crater, studying prebiotic chemistry relevant to the origins of life. • Mission: Dragonfly | Agency: NASA / Johns Hopkins APL • Launch: No earlier than summer 2028 (SpaceX Falcon Heavy) • Arrival: Titan, 2034 | Mission duration: ~3.3 years • Power: Radioisotope thermoelectric generator (nuclear) • Range: >108 miles (175 km) across Titan's surface • Quote: "This milestone essentially marks the birth of our flight system." — Elizabeth Turtle, PI Story 5: China's Tianwen-3 Mars Sample Return Enters Construction Phase China's Tianwen-3 mission chief designer Liu Jizhong announced on 12 March 2026 that the mission has achieved key technology breakthroughs and is entering flight model development — building the actual spacecraft. Two Long March 5 rockets will launch in late 2028, carrying a lander/ascent vehicle and an orbiter/return spacecraft respectively. The goal is to return at least 500 grams of Martian samples to Earth by 2031 — what would be humanity's first Mars sample return. • Mis

It’s a bumper Friday edition of Astronomy Daily. NASA gives Artemis II the official green light to launch on April 1st, marking the first crewed lunar mission in over 53 years. Astronomers witness the birth of a magnetar for the very first time, confirming a decade-old theory and demonstrating Einstein’s general relativity in a supernova. A star 11,000 light-years away shows evidence of two planets catastrophically colliding in real time. A bus-sized asteroid buzzed past Earth last night closer than the Moon, discovered just five days ago. A fast solar wind stream from a coronal hole could bring auroras to higher latitudes tonight. And scientists may have identified the source of the most energetic neutrino ever recorded. Story 1: Artemis II — Green Light for April 1 Launch NASA completed its Flight Readiness Review on 12 March 2026, with all mission teams voting unanimously ‘go’ for launch. The Space Launch System and Orion capsule will roll out to Launch Complex 39B on 19 March, with the primary launch window opening on 1 April at 6:24pm ET. Backup windows exist on 2–6 April and 30 April. The crew of four — Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen — will fly a 10-day figure-eight loop around the Moon. It will be the first crewed mission beyond low Earth orbit since Apollo 17 in December 1972. The previously planned Moon landing on Artemis III has been moved to Artemis IV, though NASA’s 2028 goal for a lunar landing remains unchanged. • NASA Artemis II Mission Page: https://www.nasa.gov/mission/artemis-ii/ • CNN coverage of FRR outcome: https://www.cnn.com/2026/03/12/science/nasa-artemis-2-launch-date-risk-assessment Story 2: First-Ever Observed Birth of a Magnetar Astronomers have for the first time directly observed the birth of a magnetar — a highly magnetized, rapidly spinning neutron star — confirming it as the power source behind some of the universe’s brightest stellar explosions. The discovery, published in Nature on 11 March 2026, centres on superluminous supernova SN 2024afav, located approximately one billion light-years from Earth. Graduate student Joseph Farah at UC Santa Barbara, working with Las Cumbres Observatory’s global telescope network, detected a distinctive ‘chirp’ pattern in the supernova’s fading light — four oscillations with shortening intervals. This pattern is explained by a wobbling accretion disc around the newborn magnetar, driven by Lense-Thirring precession — a general relativistic effect. The finding confirms a 2010 theory by UC Berkeley physicist Dan Kasen, and marks the first time general relativity has been required to explain supernova mechanics. • Berkeley News: https://news.berkeley.edu/2026/03/11/astronomers-capture-birth-of-a-magnetar-confirming-link-to-some-of-universes-brightest-exploding-stars/ • Space.com: https://www.space.com/astronomy/stars/astronomers-witness-colossal-supernova-explosion-create-one-of-the-most-magnetic-stars-in-the-universe-for-the-first-time Story 3: Two Planets Caught Colliding 11,000 Light-Years Away Researchers at the University of Washington have published evidence of a catastrophic planetary collision observed in real time around star Gaia20ehk, located approximately 11,000 light-years from Earth near the constellation Puppis. The star began flickering erratically from 2016, before its light output went ‘completely bonkers’ around 2021 — the signature of a massive debris cloud from two colliding worlds passing in front of the star. The debris orbits at roughly one astronomical unit from the star — the same as Earth’s distance from the Sun — and may eventually coalesce into new planetary bodies resembling an Earth-Moon system. The paper was published 11 March in The Astrophysical Journal Letters. • University of Washington: https://www.washington.edu/news/2026/03/11/uw-astronomers-spot-planet-collision-evidence/ • ScienceDaily: https://www.sciencedaily.com/releases/2026/03/260311213429.htm Story 4: Asteroid 2026 EG1 Flies Past Earth A bus-sized asteroid designated 2026 EG1 made its closest approach to Earth at 11:27pm EDT on 12 March 2026, passing just 197,466 miles away — closer than the Moon. Estimated at 32–72 feet (10–22 metres) across and travelling at over 21,500 mph, it posed no threat. Notably, the asteroid was only discovered on 8 March — five days before its flyby — highlighting the ongoing challenge of detecting small near-Earth objects with short warning times. NASA’s Vera Rubin Observatory has already catalogued over 2,000 previously unknown solar system bodies since beginning operations. • Space.com: https://www.space.com/stargazing/bus-sized-asteroid-will-fly-past-earth-tonight-mere-days-after-being-discovered-heres-what-to-expect-march-12-2026 Story 5: Solar Wind & Aurora Alert A fast-moving stream of solar wind from a large coronal hole on the Sun is expected to reach Earth on 13 March 2026, potentially triggering G1 (minor) geomagnetic storm conditions. Auroras may be visible from higher lat
