The explosion had the energy of approximately 9000 type Ia supernovae if the emission was isotropically emitted, and the gas jets emitting the initial gamma rays moved at a minimum velocity of approximately 299,792,158 m/s (99.9999% the speed of light), making this blast one of the most extreme recorded.

New developments since the 2000s include the recognition of short gamma-ray bursts as a separate class (likely from merging neutron stars and not associated with supernovae), the discovery of extended, erratic flaring activity at X-ray wavelengths lasting for many minutes after most GRBs, and the discovery of the most luminous (GRB 080319B) and ...
It had the largest amount of energy ever recorded in the TeV range, [47] and had the most energetic photons ever recorded for a GRB, peaking at 18 TeV. [25] [20] The burst was ten times brighter than any previous GRB detected by the Swift mission. [48] It was the brightest and most intense GRB detected by KONUS-Wind. [1]
The solar system might have been hit by the brightest explosion ever seen, scientists have said. The pulse of intense radiation began its life in a cosmic explosion two billion light years away ...
Those powerful jets plough through stellar material produce strong shock waves, with the vigorous winds of newly-formed 56 Ni blowing off the accretion disk, detonating the hypernova explosion. The ejected radioactive decay of 56 Ni renders the visible outburst substantially more luminous than a standard supernova. [ 17 ]
The main explosion, involving more than 400 tons of propellant in containers, destroyed hundreds of houses within a few kilometres from the depot and broke windows in cars on the Tirana-Durrës highway. A large fire caused a series of smaller but powerful explosions that continued until 2 a.m. the next day.
The UniverseMachine (also known as the Universe Machine) is a project carrying out astrophysical supercomputer simulations of various models of possible universes, created by astronomer Peter Behroozi and his research team at the Steward Observatory and the University of Arizona.
An antimatter weapon is a theoretically possible device using antimatter as a power source, a propellant, or an explosive for a weapon.Antimatter weapons are currently too costly and unreliable to be viable in warfare, as producing antimatter is enormously expensive (estimated at US$6 billion for every 100 nanograms), the quantities of antimatter generated are very small, and current ...
