2013-08-04 05:03:18

redOrbit Staff & Wire Reports - Your Universe Online Researchers using the Hubble Space Telescope have discovered new evidence that the merger of two small, super-dense stellar objects is responsible for producing short-duration gamma ray bursts, according to research published Saturday in a special online edition of the journal Nature. Thanks to observations provided using NASA's low-orbit aperture telescope, the study authors were able to locate a new type of stellar blast known...

WATCH VIDEO: [Swift's Christmas Burst From Blue Supergiant Star Explosion] Lee Rannals for redOrbit.com — Your Universe Online Researchers unwrapped a little more of the mystery surrounding a new type of powerful cosmic explosion, creating a new theory around the death of supergiant stars. These huge explosions create powerful blasts of high energy gamma rays, known as gamma-ray bursts. These larger blasts can last for several hours, compared to most gamma-ray bursts which...

ESO's Very Large Telescope has shown that a faint gamma-ray burst detected last Thursday is the signature of the explosion of the earliest, most distant known object in the Universe (a redshift of 8.2). The explosion apparently took place more than 13 billion years ago, only about 600 million years after the Big Bang. Gamma-ray bursts (GRBs) are powerful flashes of energetic gamma-rays lasting from less than a second to several minutes. They release a tremendous amount of energy in this short...
