Seismic readings of the interior of Mars strongly suggest large quantities of water buried 6 to 12 miles underground.

Researchers are using basalt spectra to study exoplanets and search for water with the James Webb Space Telescope. By ...

Primordial supernovae got the ball rolling a quick hundred million years or so after the start of the universe.

Astrophysicists have been grappling with the question of how water arrived on our young planet for decades. One of the earliest hypotheses suggested that Earth’s water was a direct byproduct of ...
