This is so powerful the extraterrestrial explosion can create a startling brightening, known as a nova.

Astronomers saw V745 Sco fade by a factor of a thousand in optical light over the course of only nine days.

In 2014, astronomers finally got their chance to witness the phenomena, via NASA’s Chandra X-Ray Observatory.

They discovered most of the material ejected by the explosion was apparently moving towards Earth.

NASA developed a sophisticated 3D computer model of the explosion to help explain the observations.
