Summary
| Description | Mysterious and fleeting, gamma-ray bursts come from galaxies so far away that they take billions of years to reach us. NASA's new satellite called Swift will be able to quickly slew around and investigate these dynamic beacons of light, which scientists have speculated signal birth cries when block holes are formed_ Gamma ray bursts are a flash of gamma rays and then there's x-ray and optical emission that fades away quickly on minute-time scales. It lasts for hours and days after that, but it is brightest right after the burst. No other previous mission has been able to look at that spot in the sky quickly enough to see the really bright emission a few minutes fter the burst, and that's what's unique about Swift. Swift will also be able to relay the position of the GRB to scientists on the ground in less than one minute_ There are many theories about what causes gamma-ray bursts or GRB's: one is the Collapsar Model where the collapse of the core of a massive star forms |
