NASA’s Astronomy Picture of the Day

In today's image, we see the spiral galaxy known as NGC 1546 as imaged by the Hubble Space Telescope just a week ago. Hubble is using a new pointing system to help keep the telescope pointed accurately even as the accuracy of its gyroscopes degrade over time.

In today's image, we see a cluster of galaxies. Nearly every object in this image is a distant galaxy. When we measure the mass of galaxy cluster like this one, we find that there is a large amount of dark matter needed to explain the motions of the galaxies and the gravitational lensing caused by the cluster. Dark matter makes up the vast majority of the matter in the universe.My podcasts are available in video form through this YouTube Channel.This Podcast is an authorized New Media Mirror Site for APOD.

In today's image, we see a solar filament which erupted into a coronal mass ejection on the Sun back in 2012. The Sun has a cycle of activity that lasts about 11 years and is near the peak of that activity cycle again right now. So, we are seeing more events like this which cause aurora here on Earth like those we saw a couple of weeks ago.

In today's image, we see the Manicouagan impact crater as seen from the International Space Station. The crater, about 100km across has worn down over the past 200 million years so that we just see the remnants of the crater in the form of a circular lake. Because of weathering and erosion, craters last a much shorter time on Earth than on our Moon.

In today's image, we see two galaxies in the process of colliding together. When galaxies collide, their gravitational fields interact so that material is pulled out in streams as we see around the galaxy on the left. The process also takes a very long time - hundred of millions of years - so we only see a single snapshot of the collision.My podcasts are available in video form through this YouTube Channel.This Podcast is an authorized New Media Mirror Site for APOD.

In today's image, we see an aurora from 2016 as seen over Sweden. The green color of the aurora is caused when charged particles from the Sun strike Earth's magnetic field and are funneled to the atmosphere near the north and south magnetic poles. They then excite oxygen atoms in Earth's upper atmosphere, causing the green glow.My podcasts are available in video form through this YouTube Channel.This Podcast is an authorized New Media Mirror Site for APOD.

In today's image, we see an image of the aurora taken back on May 10 after the emission of a coronal mass ejection from the Sun by a large sunspot group crossing its face. That sunspot group has now moved around to the back side of the Sun as seen from Earth, but may last long enough to still be visible as the Sun continues to rotate. The sunspot would be back on our side of the Sun in another week or so.

In today's image, we see the Aurora Australis which is the aurora when seen in the southern hemisphere. That cause is exactly the same as the aurora seen in the Northern Hemisphere. The aurora have been prominent this past week because of the large sunspot group AR 3664 which has recently moved around the limb of the Sun due to the Sun's rotation.

In today's image, we see some of the auroral displays as seen over Georgia in the United States just about a week ago. The strong auroral displays were caused by the large sunspot group on the Sun which had emitted large numbers of charged particles which excite oxygen atoms in Earth's atmosphere, causing them to glow.

In today's image, we see an artist's conception of what would happen as a black hole tears apart a passing star. Once the material crosses the event horizon, nothing can be known about it. However, material will often swirl in an accretion disk as it enters the black hole, giving off energy and allowing us to detect the black hole's presence.

In today's image, we see three Auxiliary Telescopes which are used with the VLT telescopes to simulate larger mirrors using interferometry. This allows observations from different telescope to be combined together to simulate the resolution of a much larger telescope.

In today's image, we see an illustration of the orbit of the exoplanet WASP-43b. This is a nearby planet, less than 300 light years from Earth. It is an example of a "Hot Jupiter" - a large planet which orbits very close to its star. Measurement from the James Webb Space Telescope are helping us to learn more about the temperatures in the atmosphere of this planet.
