Using the James Webb Space Telescope (JWST), astronomers have observed a nearby cold brown dwarf designated WISEPA J182831.08+265037.8 (or WISE 1828 for short). The observations delivered important insights into the composition ...
The James Webb Space Telescope (JWST) captured images of a brown dwarf with silicate particles in its atmosphere. In their paper posted on the arXiv preprint server, astronomers describe their analysis of the brown dwarf ...
(PhysOrg.com) -- NASA's Spitzer Space Telescope has discovered something odd about a distant planet -- it lacks methane, an ingredient common to many of the planets in our solar system.
