Shimmering aurora flicker above Saturn’s north pole
An aurora by any other name? Not if it goes by STEVE
Brown dwarf or massive exoplanet detected with powerful magnetic field
“Failed stars” host powerful auroral displays
Brown dwarfs are relatively cool, dim objects that are too massive to be planets, yet they are too small to sustain hydrogen fusion reactions. By observing a brown dwarf 20 light-years away, researchers have found another feature that makes these so-called failed stars more like supersized planets — they host powerful aurorae near their magnetic poles.
