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]

Hubble Finds 'Smoking Gun' After Gamma-Ray Blast

  NASA’s Hubble Space Telescope recently provided the strongest evidence yet that short-duration gamma-ray bursts are produced by the merger of two small, super-dense stellar objects. Compass and Scale Image for GRB 130603B. The galaxy (SDS J112848.22+170418.5) which resides almost 4 billion light-years away, produced the gamma-ray burst. Image Credit: NASA, ESA, and Z. Levay (STScI/AURA) The evidence [continue reading]

The Birth of a Black Hole Not as Boring as Thought

  A new kind of cosmic flash may reveal something never seen before: the birth of a black hole.   When a massive star exhausts its fuel, it collapses under its own gravity and produces a black hole, an object so dense that not even light can escape its gravitational grip. According to a new [continue reading]

Record -Breaking Supernova  Helps Understand Distant Galaxy

  Nature hath no fury like a dying star – and astronomers couldn’t be happier…   An international research team, led by Edo Berger of Harvard University, made the most of a dying star’s fury to probe a distant galaxy some 9.5 billion light-years distant. The dying star, which lit the galactic scene, is the [continue reading]
