This is followed by what is known as afterglow.Ī supernova is expected near the location of BOAT, which is approximately 1,9 billion light-years from Earth. According to Burns, the black hole feeds jets traveling at just below the speed of light.īurns continued: “As these jets fade, they release their energy as rapid emission of gamma-ray bursts.” The energy accumulated in this star then fuels a supernova explosion. “So the center collapses and a black hole is formed. On the other hand, most long GRBs are produced by black holes, which are formed when massive stars collapse and die. Collisions between neutron stars, superdense stellar remnants, and other objects likely produce the short variety, according to astronomers. Short GRBs, which can last two seconds or less, and long GRBs, which can last for minutes, are two different types that astronomers distinguish. They produce more energy in a few seconds than the Sun has produced in its 10 billion years of existence. The most powerful explosions in the universe are GRBs. Therefore, there is a chance that this gamma-ray burst may be the brightest burst to hit Earth since the beginning of human civilization. The 20th meeting of the High Energy Astrophysics Division of the American Astronomical Society was held in Hawaii on Tuesday, March 28, and Eric Burns, assistant professor of physics and astronomy at Louisiana State University, spoke at a press conference here.īurns continued: “The BOAT is an event that occurs once every 10.000 years.
It's just a massive explosion, that's all.
