Beyond our solar system, aurorae have been inferred from radio observations of isolated brown dwarfs (e.g. Hallinan et al. 2006; Kao et al. 2023). Within our solar system, giant planets […]

Atmospheric Methane Found On Brown Dwarfs W1935 And W2220
Astronomers used the NASA/ESA/CSA James Webb Space Telescope to study 12 cold brown dwarfs. Two of them – W1935 and W2220 – appeared to be near twins of each other […]

Presence Of Methane Suggests Brown Dwarf Atmospheric Heating By Auroral Processes
Astronomers using NASA’s James Webb Space Telescope have found a brown dwarf (an object more massive than Jupiter but smaller than a star) that may display possible aurorae, like the […]
