Galaxy

Geologists claim to have discovered a long-term cycle that may link the formation of Earth’s continents to our travels through the galaxy. The team claims a correlation between increased comet impacts and Earth crossing the galactic spiral arms.

The James Webb Space Telescope keeps breaking its own records for peering deeper into space and time. It's now detected a galaxy candidate about 35 billion light-years from Earth, which if confirmed would make it the most distant galaxy ever found.

Another stunning example of the James Webb Space Telescope's power has arrived courtesy of the instrument's advanced infrared cameras, which have illuminated incredible new components of what's known as the Cartwheel Galaxy.

Everything has to end eventually – including the universe itself. It might be hard to imagine a catastrophe big enough to affect the entirety of existence, but here are some of the leading hypotheses about how the universe could end, and when.

If you’ve seen the first images from the James Webb Space Telescope this week, you might have heard the term “gravitational lensing” being thrown around. But what does it mean exactly? And how can it help this new telescope make discoveries?

By now you’ve no doubt seen the first batch of images from NASA’s powerful new James Webb Space Telescope. But the scope of the achievement is hard to appreciate without context, so here they are side-by-side with Hubble’s views of the same regions.

After yesterday's sneak peek of things to come, a host of new images from NASA's James Webb Telescope are pouring in. The largest of them reveals "never-before-seen" details of a galaxy group known as Stephan's Quintet.

Astronomers have discovered bizarre “blue blobs” in space. These blobs are clusters of young, blue stars that are isolated from any parent galaxy, suggesting they formed from a galactic “belly flop.”

The most comprehensive picture of the Milky Way just got more detailed. Gaia's third data release covers almost 2 billion stars, including their makeup and movements, plus new catalogs of starquakes, binary systems, variable stars and other objects.

NASA has released a huge new report that astronomers are calling Hubble’s magnum opus. Analyzing 30 years of data from the famous space telescope, the new study makes the most precise measurement yet of how fast the universe is expanding.

The Milky Way is one of the night sky’s most majestic subjects for photography, so it's the star of travel blog Capture the Atlas's annual competition. The 25 winning shots of this year’s Milky Way Photographer of the Year have now been unveiled.

Astronomers have discovered what may be the brightest pulsar in the sky. Despite its intense light the pulsar has long evaded detection, and was only revealed thanks to a telescope equipped with some cosmic “sunglasses.”
