Researchers armed with the Hubble Space Telescope have revealed that some of Uranus' largest moons have one side brighter than the other — but not the side they were expecting.

Space weather experts warn that a "moderate" geomagnetic storm could rock Earth over the weekend, potentially lighting the skies with vibrant auroras across large parts of the U.S. and Europe.

NASA's Chandra X-ray Observatory has captured a striking image of a distant quasar from the "cosmic noon," including a giant energy jet "being illuminated by the leftover glow from the Big Bang itself."

A new image released by China's space agency offers the first glimpse at the Tianwen 2 spacecraft, which is en route to collect samples from one of Earth's "quasi-moons". The photo shows some surprising similarities with a current NASA probe.

The private Japanese spacecraft "Resilience" has seemingly been destroyed in a "hard landing" on the moon on Thursday. The lander was carrying what would have been the first European-built rover to explore the moon.

A pair of new studies has revealed that the hellish skies of exoplanet WASP-121b contain silicon monoxide gas, which has never been found in any planetary atmosphere to date.

A new study suggests that unidentified "co-orbital asteroids" around Venus may have the capacity to impact our planet in the future, with potentially devastating consequences. However, there is no immediate threat.

A large sunspot has just reappeared on the sun's Earth-facing surface, almost two months after it first emerged. The unusually old dark patch remains stable and could be on course to become the longest-lived sunspot on record, experts claim.

A NASA-funded plan to build a large radio telescope on the moon's far side is nearing final approval and could become a reality by the 2030s, researchers say. The ambitious project will help safeguard astronomy from satellite "megaconstellations" — and help scientists unravel more of the radio spectrum.

New radio images reveal an unusually faint and symmetrical supernova remnant, nicknamed Telios, lurking just below the galactic plane of the Milky Way. However, they cannot tell exactly where it is, how big it is or how it formed.

A recent launch of China's Zhuque-2E rocket triggered a giant white streak of light to appear above at least seven U.S. states after deploying six satellites into low-Earth orbit. The light show, which was visible in at least seven states, was the result of a "fuel dump," experts say.

DNA analysis has revealed that 26 novel species of "extremophile" bacteria were lurking in a clean room that housed NASA's Phoenix lander before it was launched to Mars in 2007. The hardy microbes might be capable of surviving in space.

The number of satellites orbiting our planet is rising fast, thanks to private "megaconstellations" that pose various threats to space exploration and astronomy. But how big has the problem already become?

NASA's Perseverance rover recently captured a photo of green auroras shining in the Martian sky for the first time. The alien light show, previously assumed to be impossible, could be visible to future astronauts.

Astronomers have discovered that the magnetar SGR 0501+4516 is speeding through our galaxy at more than 110,000 mph. This unusually fast speed hints that it was not born as expected, which could help explain the puzzling origin of some fast radio bursts.
