How wide is a gamma ray burst?
Although their diameter may only be 20 kilometers, their mass is about 1.4 times that of the Sun. A second theory proposed that gamma-ray bursts are the result of a merging between a neutron star and a black hole or between two black holes.
How far can a gamma ray travel through air?
Gamma rays can be emitted from the nucleus of an atom during radioactive decay. They are able to travel tens of yards or more in air and can easily penetrate the human body. Shielding this very penetrating type of ionizing radiation requires thick, dense material such as several inches of lead or concrete.
How far can a gamma ray burst travel without being dangerous?
I think you meant to ask how far can a gamma ray burst travel and still be dangerous. That distance is between 3 and 10 thousand lightyears, depending on its duration. Under the inverse square law, the beam from a GRB expands rapidly
How often do gamma ray bursts (GRBs) occur?
Estimating the exact rate at which GRBs occur is difficult; for a galaxy of approximately the same size as the Milky Way, estimates of the expected rate (for long-duration GRBs) can range from one burst every 10,000 years, to one burst every 1,000,000 years.
What is the most powerful gamma ray ever observed?
In November 2019, astronomers reported a notable gamma ray burst explosion, named GRB 190114C, initially detected in January 2019, which, so far, produced gamma-rays with the highest energy – about 1 Tera electron volts (Tev) – ever observed for such a cosmic event.
How far away is a gamma ray beam from a black hole?
That distance is between 3 and 10 thousand lightyears, depending on its duration. Under the inverse square law, the beam from a GRB expands rapidly from under a millimeter across at its point of origin, just above the event horizon of a newly born stellar mass black hole, to a considerable fraction…
