Web Space Telescope Reveals Surprising Methane Activity on a Cold Brown Dwarf

Released in the journal Nature, the findings recommend that this brown dwarf might generate aurorae comparable to those seen on our own planet as well as on Jupiter and Saturn.The Study of Brown DwarfsMore enormous than planets but lighter than stars, brown overshadows are common in our solar area, with thousands determined. The mass for W1935 isnt well understood but it likely ranges in between 6– 35 times the mass of Jupiter.Unique Methane EmissionAfter looking at a number of brown overshadows observed with JWST, Fahertys team observed that W1935 looked similar however with one striking exception: it was releasing methane, something thats never ever been seen before on a brown dwarf.”Methane gas is expected in huge worlds and brown dwarfs but we normally see it absorbing light, not radiant,” stated Faherty, the lead author of the research study.
