Many planets that have the right temperatures for liquid water on their surfaces used to be too hot or too cold, which may affect their ability to host life now Space 19 January 2023 By Leah Crane Two planets orbiting a red-dwarf star (illustration) NASA/JPL-Caltech A large proportion of planets […]
Astronomers have found 65 evenly spaced rocks orbiting a white dwarf star in its habitable zone, hinting that a planet’s gravity may be holding them there Space 11 February 2022 By Leah Crane Illustration of the white dwarf star WD 1054-226 orbited by clouds of planetary debris and a major […]
A small gas exoplanet may have lost its atmosphere billions of years ago, but then gained a second one through volcanic activity, according to astronomers. The planet, GJ 1132 b, is thought to have begun as a gaseous world, similar to Jupiter or Saturn but smaller than Neptune, with a […]
This artist's illustration shows a "sky crane" gently lowering Perseverance to the surface of Mars. NASA NASA successfully landed its most advanced rover ever on the surface of another planet this week. The Mars 2020 Perseverance rover is the fifth such rolling robot the space agency has sent to the red planet, and when the mission is…

A potential Neptune-to Saturn-sized planet that ‘could be suitable for life’ has been discovered in the habitable zone of a neighboring star system. The exoplanet, dubbed ‘C1,’ was spotted in the Alpha Centauri triple star system 4.4 light-years from Earht, which is also home to Alpha Centauri A and B, […]
