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.

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 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.
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 ]
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 ...
The pulse of intense radiation began its life in a cosmic explosion two billion light years away from us. Since then, it has been smashing through the universe, reaching our solar system in ...
The most recent naked-eye supernova was SN 1987A, which was the explosion of a blue supergiant star in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. Theoretical studies indicate that most supernovae are triggered by one of two basic mechanisms: the sudden re-ignition of nuclear fusion in a white dwarf , or the sudden ...
Universe Sandbox is a series of interactive space sandbox gravity simulator educational software video games.Using Universe Sandbox, users can see the effects of gravity on objects in the universe and run scale simulations of the Solar System, various galaxies or other simulations, while at the same time interacting and maintaining control over gravity, time, and other objects in the universe ...
