An international team of astronomers has reported the discovery of a new brown dwarf, which received designation TOI-2490 b. The newfound object is about 74 times more massive than Jupiter and orbits a sun-like star on a ...
Using the Keck II telescope, astronomers have detected an object that may be a brown dwarf or a low-mass star, exhibiting a very high radial velocity. The object, designated CWISE J124909.08+362116.0 is located some 400 light ...
Astronomers have created the most detailed weather report so far for two distant worlds beyond our own solar system. The international study—the first of its kind—reveals the extreme atmospheric conditions on the celestial ...
