NASA's Space Launch System and Orion spacecraft exited the vehicle assembly building today after clearing some final tests and checks, en route to the launchpad for a maiden, uncrewed journey around the Moon.

Northrop Grumman announces that the war in Ukraine is forcing it to develop a US-designed and manufactured replacement for the first stage of its Antares rocket, which was previously made in Ukraine using Russian engines.

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.

The Moon isn’t the most hospitable place, but that’s not stopping NASA from sending humans back there soon. Thankfully, an orbiter has now found a region of the Moon with year-round jeans-and-jacket weather – underground caves.

In a major upset, Roscosmos Chief Yury Borisov announced in a meeting with Russian President Vladimir Putin that Russia will formally withdraw from the International Space Station (ISS) after 2024, putting the future of the space lab in jeopardy.

As the August launch date for NASA's first Artemis lunar mission approaches, Northrop Grumman has released a dramatic video of a full-scale static fire test of the giant solid-fueled Flight Support Booster-2 that will power the Space Launch System.

After wrapping up testing of its next-generation Space Launch System last month, NASA has now announced a series of launch windows in which it could take off for the first time – which could come as soon as next month if things run smoothly.

James Webb Space Telescope's historic first images showed a galaxy cluster billions of light-years away, but now it’s turned its sights on something much closer to home. NASA has released infrared images of Jupiter used to test Webb's instruments.

Astronomers have measured the strongest magnetic field ever found in the universe. The honor goes to a powerful type of neutron star, with a surface magnetic field of over 1.6 billion Tesla.

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?

Astronomers have detected an extremely strange radio signal from a distant galaxy that pulses with a heartbeat-like rhythm. This signal lasted about 1,000 times longer than other fast radio bursts, and had a clear periodic pattern to its pulses.

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.

In what promises to be a veritable torrent of science, NASA has released the first batch of images from the James Webb Space Telescope, including the death throes of a star, a cluster of galaxies, and "cosmic cliffs" where stars are born.
