The Constellation Godzilla

Godzilla isn’t one of the official 88 constellations. It’s a new, unofficial x-ray constellation. The NASA team responsible for the Fermi Gamma-ray Space Telescope has devised a set of constellations constructed from sources in the gamma-ray sky. The new constellations include a few characters from modern myths. Among them are the Little Prince; the TARDIS from “Doctor Who;” Godzilla and his heat ray; the antimatter-powered U.S.S. Enterprise from “Star Trek: The Original Series;” and the Hulk, the product of a gamma-ray experiment gone awry.

Gamma Ray Burst

When a massive star collapses to form a black hole, a burst of gamma rays results as particles are blasted outward at nearly the speed of light. This animation shows the most common type of gamma-ray burst. An end-on view of a jet greatly boosts its apparent brightness. One especially bright burst (GRB 130427A) was detected in 2013 by the Fermi and Swift satellites. A Fermi image of that burst ends the animation sequence.
