Astronomers have watched as a massive, dying star was likely reborn as a black hole.

A team of astronomers including Carnegie's Eduardo Bañados and led by Roberto Decarli of the Max Planck Institute for Astronomy has discovered a new kind of galaxy which, although extremely old -- formed less than a billion years after the Big Bang -- creates stars more than a hundred times faster than our own Milky Way.

Online volunteers have helped astronomers at The Australian National University find a star that exploded 970 million years ago, predating the dinosaurs' time on Earth.

The surfaces of Earth, Mars, and Titan, Saturn's largest moon, have all been scoured by rivers. Yet despite this similarity and the amazingly Earth-like landscapes of Titan complete with valleys, lakes, and mountains, researchers led by City College of New York geologist Benjamin Black report new evidence that the origins of the topography there and on Mars are different from on Earth.
