Temperate exoplanet LHS 1140 b may be a world completely covered in ice (left), similar to Jupiter’s moon Europa, or an icy world with a liquid substellar ocean and a cloudy atmosphere (center). LHS 1140 b is 1.7 times the size of Earth (right) and is the most promising exoplanet in the habitable zone found … Read more
Researchers have shown through high-energy laser experiments that magnesium oxide is likely the first mineral to solidify in the formation of a super-Earth, which has a crucial influence on the geophysical evolution of these planets. A new study finds that magnesium oxide, a key mineral in planet formation, may be the first to solidify in … Read more
Using the Hubble Space Telescope, scientists have discovered that a cotton candy-like planet the size of Jupiter, located about 350 light-years away, is shrinking and on its way to becoming a ‘sub-Neptune’ or ‘super-Earth’ ‘ format. world.
