Astronomers have discovered a pair of exoplanets orbiting an M dwarf star, one of which is the coldest M dwarf planet found by the TESS satellite observatory, making it accessible for follow-up studies of its atmosphere. ...
Astronomers using NASA's James Webb Space Telescope have found a brown dwarf (an object more massive than Jupiter but smaller than a star) with infrared emission from methane, likely due to energy in its upper atmosphere. ...
