There is strong evidence that some short-duration gamma-ray bursts occur in systems with no star formation and no massive stars, such as elliptical galaxies and galaxy halos. [112] The favored hypothesis for the origin of most short gamma-ray bursts is the merger of a binary system consisting of two neutron stars.
The gamma-ray burst was ten minutes long, [1] but was detectable for more than ten hours following initial detection. [2] [3] Despite being around 2.4 billion light-years away, it was powerful enough to affect Earth's atmosphere, having the strongest effect ever recorded by a gamma-ray burst on the planet.
GRB 080916C is a gamma-ray burst (GRB) that was recorded on September 16, 2008, in the Carina constellation and detected by NASA's Fermi Gamma-ray Space Telescope. The burst lasted for 23 minutes (1400 s). [1] [2] It is one of the most extreme gamma-ray bursts ever recorded, [3] and was the most energetic gamma-ray burst ever recorded, until ...
This gamma-ray burst, researchers said on Tuesday, caused a significant disturbance in Earth's ionosphere, a layer of the planet's upper atmosphere that contains electrically charge
GRB 190114C was an extreme gamma-ray burst explosion from a galaxy 4.5 billion light years away (z=0.4245; [2] magnitude=15.60est [3]) near the Fornax constellation, [4] [5] [6] that was initially detected in January 2019.
First burst observed simultaneously in optical and gamma-rays. Brightest observed afterglow before the launch of Swift. GRB 991216: BATSE: First burst detected by the Chandra X-ray Observatory [1] GRB 030329: z = 0.168 [Ref 5] HETE-2: The closest "classical" long GRB to Earth and the most thoroughly studied afterglow to date. GRB 050509B: z = 0 ...
Dozens of telescopes all over the world are pointing at a patch of sky that gave rise to the most powerful gamma-ray burst ever seen, hoping to shed more light on processes that birth black holes.
GRB 080319B was a gamma-ray burst (GRB) detected by the Swift satellite at 06:12 UTC on March 19, 2008. The burst set a new record for the farthest object that was observable with the naked eye: [2] it had a peak visual apparent magnitude of 5.7 and remained visible to human eyes for approximately 30 seconds.
