A Glow That Needs an Explanation
A possible auroral interpretation remains a hypothesis about a cold brown-dwarf system.
A conceptual view of one component of the W1935 brown dwarf system, showing a possible auroral curtain. W1935 is now known to be a binary; neither this aurora nor an active moon has been directly confirmed. Visible colors interpret an infrared finding.
THE OBSERVATION
What we can actually see.
Unusual infrared methane emission motivates an additional energy-input explanation for W1935. An aurora or an active companion moon has not been directly confirmed; a visible curtain is an interpretation of the proposed process.

FROM THE ILLUSTRATED ARTICLE
The story that inspired it.
The article begins with a rapidly orbiting, mass-transferring brown-dwarf pair, then expands to the small young objects and unusual infrared chemistry Webb is investigating. It separates present accretion heating from a possible future change in stellar status. This frame focuses on a possible auroral interpretation remains a hypothesis about a cold brown-dwarf system.
