Astronomers propose a novel method of finding atmospheres on rocky worlds When NASA’s James Webb Space Telescope launches in 2021, one of its most anticipated contributions to astronomy will be the study of exoplanets—planets orbiting […]
Rocky, Earth-sized exoplanet is missing an atmosphere Astronomers at MIT, Harvard University, and elsewhere have searched a rocky, Earth-sized exoplanet for signs of an atmosphere—and found none. Atmospheres have previously been detected on planets much […]
Rocky planet neighbor looks familiar, but is not Earth’s twin Last autumn, the world was excited by the discovery of an exoplanet called Ross 128 b, which is just 11 light years away from Earth. […]
Ramp compression of iron provides insight into core conditions of large rocky exoplanets In a paper published today by Nature Astronomy, a team of researchers from Lawrence Livermore National Laboratory (LLNL), Princeton University, Johns Hopkins […]
Black hole blasts may transform ‘mini-Neptunes’ into rocky worlds A team of astrophysicists and planetary scientists has predicted that Neptune-like planets located near the center of the Milky Way were transformed into rocky planets by […]
Rocky or gassy? Massive, dense super-Earth planet detected A star about 100 light years away in the Pisces constellation, GJ 9827, hosts what may be one of the most massive and dense super-Earth planets detected […]
