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. It now turns out many are very distant, … 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. However, it's pretty likely that the radiation would not have an impact on Earth. It … 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.
