Gamma Ray Ghouls
When the cores of two giant stars collide, they produce a violent, shrieking burst of light known as a gamma ray burst.
Gamma ray bursts are the most powerful form of light, and they shine a million times brighter than the Sun for a brief, 30-second window of existence. The two energy beams depicted in the poster reveal how the gamma ray bursts take place in real life, traveling in opposite directions from the colliding stellar corpses, according to NASA.
