Two Cosmic Explosions Unveiled

  A team of researchers including Carnegie’s Mansi Kasliwal and John Mulchaey used a novel astronomical survey software system—the intermediate Palomar Transient Factory (iPTF)—to link a new stripped-envelope supernova, named iPTF13bvn, to the star from which it exploded. The iPTF team also pinpointed the first afterglow of an explosion called a gamma-ray burst that was [continue reading]

A 12.7 Billion Years Old Galaxy Discovered

  More than 12 billion years ago a star exploded, ripping itself apart and blasting its remains outward in twin jets at nearly the speed of light. At its death it glowed so brightly that it outshone its entire galaxy by a million times. This brilliant flash traveled across space for 12.7 billion years to [continue reading]

Supernova Remnant is Creating New Molecules

  Astronomers using ALMA, the Atacama Large Millimeter/submillimeter Array, have detected, for the first time, the formation of new molecules in the remains of a star that went supernova. By detecting and mapping the distribution of these molecules, the researchers also have caught a glimpse of the final internal structure of the star, which became [continue reading]
