Astronomers have discovered a distant planet that they think could be completely covered in water, making it a prime target for future study by the James Webb Space Telescope.. The planet is ...

Astronomers have discovered a nearby exoplanet that may prove to be the first such world covered in water.. TOI-1452 b is an exoplanet slightly larger and more massive than Earth about 100 light ...

Living on this planet, covered in water or not, would feature relatively lightning-fast years as the planet orbits its sun every 11 days. NASA said that because the star it orbits is smaller and ...

Scientists investigated how much water Mars once had, before the planet lost it to space and elsewhere. They found the now-desert world could have had a water content similar to Earth.

While 70 per cent of planet Earth’s surface is covered in water, water actually makes up less than 1 per cent of our planet’s mass. The astronomers' analysis found as much as 30 per cent of ...

The distant planet, which is outside of our solar system about 40 light-years away, is totally covered in a deep haze that has made it difficult to study since it was first discovered in late 2009 ...

The images and data being collected are already raising new questions about how the Martian surface was changing billions of ...

LP 791-18 d orbits a red dwarf it is tidally locked to, meaning the planet doesn’t have a day and night cycle like Earth. Instead, one part of LP 791-18 d is constantly scorched by sunlight ...

Get Kevin Costner on the phone – astronomers may have found some water worlds. Two nearby planets have been found to be covered in deep global oceans under hot, steamy atmospheres.

Traces of ancient streams wind across its surface, hinting at a time when water covered much of the planet. While some of this water is now locked deep underground, the fate of the rest has ...
