Aurorae on a Cold Brown Dwarf,
**Aurorae on a Cold Brown Dwarf: A James Webb Space Telescope Discovery** In the vast expanse of the cosmos, the James Webb Space Telescope (JWST) has made a groundbreaking discovery that could reshape our understanding of brown dwarfs, often referred to as 'failed stars.' Astronomers have detected signs of methane emission on a cold brown dwarf, an observation that has left scientists both baffled and exhilarated. # The Discovery The brown dwarf in question, designated as W1935, is a relatively nearby celestial body located 47 light-years from Earth. With a surface temperature of approximately 400° Fahrenheit, W1935 is considered cold by stellar standards. This temperature is far too low for such methane emissions to occur naturally, which is why the discovery by JWST is so intriguing. # The Significance Methane is commonly found in the atmospheres of gas giants like Jupiter and Saturn, where it absorbs light. However, the emission of methane from a brown dwarf is unprecedente
