Don’t be fooled! The cosmic swirl of stars in this Hubble Space Telescope (@NASAHubble) image may seem tranquil and unassuming, but this spiral galaxy actually displays some explosive tendencies.
In October of 2011, a cataclysmic burst of high-energy gamma-ray radiation — known as a gamma-ray burst — was detected coming from the region of sky containing this galaxy. Astronomers believe that the galaxy was the host of the burst, given that the chance of a coincidental alignment between the two is roughly 1 in 10 million. At a distance of around 185 million light-years from Earth, it was the second-closest gamma-ray burst ever detected.
