Engaging the Hubble Space Telescope, Swift satellite and the Chandra X-ray Observatory, astronomers at the University of Warwick were quick to choose up a signal from Swift’s Burst Alert Telescope on March 28, 2011. In a traditional line from Effortless Rider, Jack Nicholson states: “It’s a UFO beaming back again at you.” But this time it isn’t a UFO… it’s the dying scream of a star currently being consumed by a black hole. The alert was just the beginning of a sequence of x-ray blasts that turned out to be the greatest and most luminous occasion so much recorded in a distant galaxy.
Originating 3.8 billion light years from Earth in the direction of the constellation of Draco, the beam consisting of large energy X-rays and gamma-rays remained amazing for a period of time of weeks following the preliminary celebration. As far more and a lot more substance from the doomed star crossed over the function horizon, vivid flares erupted signaling its demise. Says Dr. Andrew Levan, lead researcher on the paper from the University of Warwick “Despite the power of this the cataclysmic function we nevertheless only take place to see this function due to the fact our solar system occurred to be looking appropriate down the barrel of this jet of energy”.
