The aurora detected on this cold, isolated failed star is puzzling astronomers, who aren’t sure what’s causing the light show.

The brown dwarf is an isolated object in space with no nearby star to create an aurora.

Baltimore MD (SPX) Jan 10, 2024 - Astronomers using NASAs 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 i

NASA's James Webb Space Telescope has made a surprising observation, detecting aurorae on a cold, lonely brown dwarf known as W1935.

Astronomers identified a brown dwarf, known as W1935, that exhibits unusual infrared emission from methane that resembles an aurora.

Infrared emission from methane suggests atmospheric heating by auroral processes.

Citizen scientists are joining astronomers to use NASA's flagship telescope to learn more about these "failed stars."

Citizen scientists have discovered a new object orbiting a Sun-like star that had been missed by previous searches. The object is very distant from
