A study published in the April 10 issue of Science analyzed how much water the planet once had. Researchers used several Earth-based telescopes to look at the martian atmosphere in infrared light.

This giant deposit might be hiding a frozen ocean under layers of ancient Martian dust. If that ice melted, scientists say, it could flood the entire surface of Mars in water nearly nine feet deep.

Scientists discovered evidence of a reservoir of liquid water seven to 13 miles below the Martian surface, lingering in the ...

New research suggests Mars could have enough water under its surface to form a global ocean. On Monday, scientists released their findings, which are based on seismic measurements captured from ...

Water trap Our planet may be blue from the inside out. Earth’s huge store of water might have originated via chemical reactions in the mantle, rather than arriving from space through collisions ...

The paper also notes the lack of ammonia on TOI-270 d, which it said was "consistent with predictions for a Hycean world with a planet-wide ocean" under a hydrogen-rich atmosphere.

The water-rich minor planet once orbited GD61, a star located about 150 light years away from Earth. The star ran out of fuel about 200 million years and shrank down to a cool and dense white dwarf.

This brings us to Under The Firmament, by the Iro Haala Ouranos Ensemble. A "firmament" is defined as "the sky, especially when regarded as a tangible thing." On an initial listen, the cohesiveness of ...

NASA's Mars Perseverance rover has released photos of Martian rocks that are thought to have once been under liquid water.. The rover took the photos on August 10, its 168th Martian day. One shows ...

If it melted, it would cover the entire planet with “a layer of water 1.5 to 2.7 meters deep”, so “enough water has been found in this part of Mars to completely cover Earth’s Red Sea ...
