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.

Researchers bombarded lichens with a year's worth of Martian radiation in just 5 hours — and they survived, hinting that the extremophiles could potentially live on the Red Planet.

New research suggests that the unexpected intensity of the ongoing solar maximum may be partly tied to a lesser-known, 100-year solar cycle. If true, solar activity could spike further in the coming decades. But some experts are skeptical.

Photos show that comet C/2025 F2 (SWAN) experienced a "major eruption," causing it to become temporarily brighter. However, it's still unclear whether the icy object is a true "cryovolcano."

Rocket start-up SpinLaunch wants to catapult hundreds of flattened "microsatellites" into space at once, using a cannon-like machine that accelerates objects by spinning them. The first orbital demonstration is scheduled for next year.

A pair of white dwarfs, located just 150 light-years from Earth, appears doomed to die in a type 1a supernova that will shine brighter than anything currently visible in the night sky. But humanity — and our planet — will be long gone before this happens.

Comet SWAN25F was discovered using photos from the European Space Agency's SOHO spacecraft and can currently be spied using backyard equipment — but it could also become visible to the naked eye in the next few weeks.

Video footage captured by NASA's Perseverance rover shows a small "dust devil" merging with a much larger twister on the surface of Mars.

SpaceX's Starship has been awarded a NASA contract that will allow it to be considered for future missions. However, recent explosive tests have shown the supersized spacecraft is still far from mission-ready.

The recently launched Fram2 mission, which is funded and led by cryptocurrency billionaire Chun Wang, will attempt to grow mushrooms, test out hormone diapers and X-ray civilian astronauts. However, experts say that these novel experiments are unlikely to yield meaningful results.

An eerie new video from ESA's Solar Orbiter shows a towering 'cyclone' of plasma exhibiting behaviors never seen before on our sun.

A giant whirlpool of light, known as a "SpaceX spiral," was recently spotted swirling across the night sky over Europe as a Falcon 9 rocket prepared to reenter Earth's atmosphere after deploying top-secret cargo.

Skygazers have been waiting for over a year to see a recurrent nova that creates a temporary, super-bright star every 80 years or so. A new study suggests that it could finally happen this week — but nothing is certain.

The hefty space rock 2014 TN17 is large enough to wipe out a city, but it will pose no risk to our planet when it sails by this Wednesday (March 26). Researchers will monitor it carefully during its close approach.

U.K. start-up Pulsar Fusion has unveiled plans to build a fleet of reusable nuclear fusion-powered rockets, known as Sunbirds, that could cut journey times across the solar system in half. But not everyone is convinced.

As Venus approaches its inferior conjunction, astrophotographers have snapped some striking shots of the crescent planet looking like a giant rainbow in space.
