Surprise! Brown Dwarf Star Has Dusty Skies, Appearing Strangely Red

by Elizabeth Howell February 6, 2014

Dust clouds on a brown dwarf or “failed star” are making it appear redder than its counterparts, new research reveals. Better studying this phenomenon could improve the weather forecast on these objects, which are larger than gas giant planets but not quite big enough to ignite nuclear fusion processes to become stars. “These are not […]

Forging Stars – Peering Into Starbirth and Death

by Tammy Plotner November 27, 2013

Some 160,000 light years away towards the constellation of Dorado (the Swordfish), is an amazing area of starbirth and death. Located in our celestial neighbor, the Large Magellanic Cloud, this huge stellar forge sculpts vast clouds of gas and dust into hot, new stars and carves out ribbons and curls of nebulae. However, in this […]
