DART Mission Successfully Boops Dimorphos
After ten months of space travel, NASA's DART spacecraft arrived at the asteroid Didymos, targeted the moonlet Dimorphos, and successfully flung itself at the surface. Multiple observations confirm that the system brightened and even managed to resolve a cloud of debris. Plus, rocket launches, an update on the SLS, some broken physics, and International Observe the Moon Night.
Quasar's Light Echoes After 6.73 Years
Astronomers using the 1.2-meter Whipple Observatory to follow the brightness of a lensed galaxy for 14.5 years have calculated that the time delay between light arriving along the shortest and farthest paths is 6.73 years. Plus, DART, Hayabusa2, Juno, fast radio bursts, and This Week in Space History, we look back at NASA's 1990s attempts to reach Mars.
Bringing Telescopes to Students in Libya
Beth is joined by Mike Simmons, the founder of Astronomy for Equity, an Affiliate Research Scientist at the Blue Marble Space Institute of Science, and a member of the Board of Directors for the International Dark-Sky Association. Mike is here to talk with us about a new crowdfunding campaign to bring telescopes to astronomy outreach students in Libya.
Being a Star: Nature vs Nurture
Asteroseismologists are combining data from TESS, Kepler, and eventually JWST to study stellar oscillations in 'infant' stars, with the goal of creating new models for how such young stars form and evolve over time. Plus, JWST images Mars, Hubble images stars, and SpaceX manages to launch another Starlink mission in spite of weather delays.
Saturn's Rings are Made of a Broken-up Moon
Using computer simulations, researchers have pieced together a possible scenario where Titan caused another of Saturn's moons to break up and become the beautiful ring system we see today. Plus, organic molecules on Mars, the death of the dinosaurs, and a review of Lightyear on Disney+.
Mount Sharp, Mars, Shaped by Water and Wind
Data and images from NASA's Curiosity rover found evidence that wind played a key role in erosional processes on the red planet, despite the lower atmospheric volume. Plus, astrophysics and cosmology news, a baby exoplanet, and this week in space history, we look back at an uncrewed lunar mission from Japan.
