      ALMA Catches Beautiful Outcome of Stellar Fight

      Astronomers have spotted a peculiar gas cloud that resulted from a confrontation between two stars. One star grew so large it engulfed the other which, in turn, spiraled towards its partner provoking ...

      Meteorite Chunk Contains Unexpected Evidence of Presolar Grains

      An unusual chunk in a meteorite may contain a surprising bit of space history. Presolar grains -- tiny bits of solid interstellar material formed before the sun was born -- are sometimes found in ...

      Stardust from Red Giants

      Some of the Earth's building material was stardust from red giants. Astronomers can also explain why the Earth contains more of this stardust than the asteroids or the planet Mars, which are ...
