Comets contained vast oceans of liquid water in their interiors during the first million years of their formation, a new study claims.

Liquid water has not been found on the Martian surface within the last decade after all, according to new research.

Astronomers have discovered the most Earth-like planet outside our Solar System to date, an exoplanet with a radius only 50% larger than the Earth and capable of having liquid water. Using the ESO 3.6-m telescope, a team of Swiss, French and Portuguese scientists discovered a super-Earth about 5 times the mass of the Earth that orbits a red dwarf, already known to harbour a Neptune-mass planet.
