Did you know?
Web7 sep. 2024 · A gamma-ray burst (or GRB) is a powerful explosion of these rays. Individual bursts can vary significantly in duration — lasting just a few milliseconds or as long as several hours. Most bursts are “long bursts,” which last longer than two seconds. A smaller portion of bursts are short bursts that last less than two seconds. Web29 mei 2009 · Gamma-ray bursts (GRBs) are likely to have made a number of significant impacts on the Earth during the last billion years. The gamma radiation from a burst within a few kiloparsecs would quickly deplete much of the Earth's protective ozone layer, allowing an increase in solar ultraviolet radiation reaching the surface.
Web8 dec. 2014 · A gamma-ray burst (GRB) is an intense flash of radiation from a dying star that could damage or eliminate life on a planet light years away. A pair of astrophysicists has now analyzed the latest astronomical data to update previous estimates of the likelihood that a GRB affected life on Earth. They found that there’s a 60 % chance that a GRB ... Web27 jul. 2024 · Using NASA's Fermi Gamma-ray Space Telescope, astronomers picked up what is known as a gamma-ray burst, or GRB, that had raced towards Earth from deep space. It has been named GRB 200826A.
