New York (PTI): Astronomers using NASA’s Swift satellite and Fermi Gamma-ray Space Telescope have been witnessing frequent blasts from a stellar remnant 30,000 light-years away, the American space agency reported.

The high-energy fireworks arise from a rare type of neutron star known as a soft-gamma-ray repeater. Such objects unpredictably send out a series of X-ray and gamma-ray flares, NASA reported.

“At times, this remarkable object has erupted with more than a hundred flares in as little as 20 minutes,” said Loredana Vetere, who is coordinating the Swift observations at Pennsylvania State University.
