Can a gamma ray burst destroy earth

Gamma-ray bursts are giant explosions in distant galaxies that send out swarms of powerfully energetic gamma rays. Stars, supernovae and other objects in space radiate away their energy in various forms of light, including visible light, x-rays, gamma rays, radio waves, and neutrinos, to name a few. … See more What causes GRBs? For a long time, they remained quite mysterious. They are so bright that at first people thought they might be very close. … See more Collimating the energy of the blast means that a lot of it gets focused into a narrow beam. If Earth happens to be along the line of sight of the focused blast, instruments detect … See more Current estimates are that a gamma-ray burst will happen in our galaxy, or in a nearby galaxy, about once every five million years. … See more In general, astronomers detect about one burst a day. However, they only detect those that beam their radiation in the general direction of Earth. So, astronomers are … See more Web2 days ago · TeV gamma-rays are also seen from mysterious gamma-ray bursts and other fleeting, transient events. These are now informing our understanding of the extreme conditions in which gamma rays are created.
