Latest GRB 050509b Stories
In its first five years in orbit, NASA's Swift satellite has given astronomers more than they could have hoped for.
Scientists using NASA's Swift satellite have found evidence of a black hole swallowing a neutron star. The discovery is reported in the December 15 issue of Nature.
An international team of astronomers led by Danish astronomer Jens Hjorth  has for the first time observed the visible light from a short gamma-ray burst (GRB). Using the 1.5m Danish telescope at La Silla (Chile), they showed that these short, intense bursts of gamma-ray emission most likely originate from the violent collision of two merging neutron stars. The same team has also used ESO's Very Large Telescope to constrain the birthplace of the first ever short burst whose position could...
Astronomers have uncovered tantalizing insights into the origin of short gamma-ray bursts â€“ mysterious, split-second high-energy flashes that have eluded detailed study until now. Unlike their long-duration cousins, which are known to arise when massive young stars die, short bursts are thought to occur when old, dense neutron stars collide.
