NASA’s James Webb telescope detects unexpected aurora

An unexpected aurora-like signal has been observed emanating from a brown dwarf situated some 47 light years away from Earth.

The James Webb Space Telescope discovered possible auroral indications coming from a brown dwarf known as W1935.

Brown dwarfs are cosmic entities having a mass higher than Jupiter but smaller than a star.

They are often referred to as failed stars.

Infrared measurements from the Webb telescope detected methane emissions in the atmosphere of W1935, indicating atmospheric heating driven by auroral processes.

Intriguingly, W1935 defies expectations for auroral formation by not being a hot object; instead, evidence shows it is a cold entity with no parent star.
