Scientists used the 'Mars Chamber' in the UK to simulate a process that creates 'very strange' gulleys on the red planet.

CO₂ ice blocks on Mars may dig gullies as they slide and sublimate in the thin atmosphere. In lab experiments, scientists recreated these eerie, worm-like movements under Martian conditions. The ...

Analyses of its emissions using NASA’s Neil Gehrels Swift Observatory indicate that the interstellar comet probably has a ...

Scientists suggest that dry ice on Mars may move and burrow beneath the surface, creating patterns similar to sandworms from Dune and shedding light on the planet’s changing landscape.

An interstellar visitor is speeding through the solar system, and within weeks, astronomers hope to learn whether it's a natural wanderer or something far more extraordinary. The ...

Interstellar visitor 3I/ATLAS has been constantly changing as it makes its way through our solar system. That's to be ...

NASA's Perseverance rover may have captured early images of interstellar comet 3I/ATLAS. While a viral photo shows a bright, ...

The interstellar object 3I/ATLAS is thought to be roughly 7 billion years old, making it even older than our solar system.

Michigan State University assistant professor Darryl Seligman has led the first-ever scientific paper published about ...

Astronomers analyzing observations of interstellar comet 3I/ATLAS using the W. M. Keck Observatory have discovered further ...

Six years after the discovery of the first confirmed interstellar visitor, Comet 2I/Borisov, scientists are abuzz with fresh ...

According to new research, the answer is far more unusual — and has nothing to do with life. Instead, the gullies appear to ...
