A new study found that the first stars in the universe were not only massive, but also fast-spinning. These stars died out long ago, but astronomers are able to see what they were like by looking at later generations of stars. Cristina Chiappini of the Astrophysical Institute Potsdam in Germany, and colleagues reanalyzed data from the Very Large Telescope of a 12-billion-year-old star cluster.  The team found high levels of metal in the stars. These levels suggest earlier generations...

The next generation of adaptive optics has arrived at the Large Binocular Telescope in Arizona, providing astronomers with a new level of image sharpness never before seen. Developed in a collaboration between Italy's Arcetri Observatory of the Istituto Nazionale di Astrofisica, or INAF, and the University of Arizona's Steward Observatory, this technology represents a remarkable step forward for astronomy. "This is an incredibly exciting time as this new adaptive optics system allows us to...

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 published in a recent issue of the Astrophysical Journal Letters, Ohio State University astronomers and their colleagues suggest that these star systems are the progenitors of a rare type of supernova.They discovered the first star system 13 million light years away, tucked inside Holmberg IX, a small galaxy that...

An international team of astronomers using the Large Binocular Telescope (LBT) in Arizona has discovered that the Hercules Dwarf Galaxy is shaped like a cigar. That makes it an oddball among millions of its peers. The Hercules Dwarf is a companion galaxy to our own Milky Way, but has only one ten-millionth as many stars. It was among several dwarf galaxies discovered earlier this year by the Sloan Digital Sky Survey. Now astronomers using the LBT have discovered that this tiny galaxy, which...
