While the common perception of asteroids is that they are giant rocks lumbering about in orbit, a new study shows they actually are constantly changing 'little worlds' that can give…
Research by a Michigan State University scientist sheds new light on how stars and galaxies were formed back in the early days of the universe - some 13 billion years ago…
Astronomers are announcing today that a sequence of images collected with the Smithsonian's Submillimetre Array (SMA) clearly reveals the presence of a rotating molecular disk orbiting…
Astronomers from the National Optical Astronomy Observatory in Tucson have found what looks like two massive black holes orbiting each other in the centre of one galaxy. It has been…
Researchers have discovered evidence that blue stragglers in globular clusters, whose existence has long puzzled astronomers, are the result of 'stellar cannibalism' in binary stars.…
Life on a planet ruled by two suns might be a little complicated. Two sunrises, two sunsets. Twice the radiation field. In a paper published in the December 2008 issue of Astronomy…
Theoretical models of stellar formation propose the existence of very massive stars that can attain up to 150 times the mass of our Sun. Until very recently, however, no scientist had…
Asteroids with moons, which scientists call binary asteroids, are common in the solar system. A longstanding question has been how the majority of such moons are formed. In this week's…
Astronomers have spied a faraway star system that is so unusual, it was one of a kind - until its discovery helped them pinpoint a second one that was much closer to home. In a paper…
Astronomers studying a nearby galaxy have spied a rare type of star system - one that contains a black hole that suddenly began glowing brightly with X-rays. Though this type of star…
