Before exploding at the end of its life cycle, the star is believed to have had a mass at least eight times greater than our sun. It was located in our Milky Way galaxy about 800 light years from Earth in the direction of the constellation Vela. A light year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km).
The eerie image shows clouds of gas that look like pink and orange tendrils in the filters used by the astronomers, covering an expanse roughly 600 times larger than our solar system.
