Scientists Say: Accretion Disk
Cosmic swirls of gas, dust and plasma, accretion disks reveal the shadowy silhouettes of black holes and more.

NASA is readying to send humans back to the moon
The launch of NASA's Artemis I is a huge step toward sending humans back to the moon and beyond.

Jets may have sculpted rings of Cat’s Eye nebula
The Cat’s Eye nebula is one of the most complex of its kind. A 3-D model now reveals the source of that complexity.

Mysteries about the universe abound, from its beginning to its end
Scientists have a good understanding of the laws that make our universe tick. But they still don’t quite know how it began — or will end.

NASA’s DART spacecraft successfully bumped an asteroid onto a new path
The spacecraft’s intentional crash into an asteroid changed the space rock’s orbit by more than 30 minutes — far more than expected.

A missing moon could have given Saturn its rings — and tilt
The hypothetical moon is being called Chrysalis. It could have helped tip the planet over before getting shredded to form Saturn’s rings.

NASA’s DART spacecraft crashed into an asteroid — on purpose
This mission could provide a blueprint for how to deflect a killer asteroid, if one is ever found headed for Earth.

Let’s learn about gravitational waves
Gravitational waves offer scientists a new way to view extreme objects such as black holes and neutron stars.

Amateur astronomers reveal clues to a mysterious double aurora
Stunning images from citizen scientists show an unusual pattern in ‘Northern Lights.’ They offer clues that may help astronomers better understand a curious red glow.

Scientists Say: Habitable Zone
The habitable zone is the region around a star where temperatures could be right for worlds to host liquid water.

A massive rogue roaming our galaxy may be a black hole
Alternatively, this unseen wanderer might be a hefty neutron star. Whatever it is, its gravity caused starlight to be warped — and that gave it away.

We finally have an image of the black hole at the heart of our galaxy
New observations from the Event Horizon Telescope reveal the chaotic region around the Milky Way’s central black hole, Sagittarius A*, in extreme detail.
