Mystery of gamma ray bursts solved
Washington, Oct 6: Scientists at NASA have solved the mystery of the origin of gamma ray bursts, the most powerful explosions known in space.

But researchers at [Only Registered users can see links .

"Gamma-ray bursts in general are notoriously difficult to study, but the shortest ones have been next to impossible to pin down," said Neil Gehrels, the lead investigator of NASA's Swift satellite. "All that has changed. We now have the tools in place to study these events," he said. The satellite detected a burst in May and NASA's High-Energy Transit Explorer detected another in July. Based on these findings, the theory was developed. The findings will be published in the Oct 6 issue of Nature magazine. NASA said the new discoveries could help scientist detect gravitational waves - ripples in space time that have never been seen. "Short gamma-ray bursts could tell scientists when and where to look for the ripples," a NASA statement said. More than 130 scientists are in the project, the agency said. "We had a hunch that short gamma-ray bursts came from a neutron star crashing into a black hole or another neutron star, but these new detections leave no doubt," said Derek Fox, a researcher with Pennsylvania State University.
