The planetary nebula NGC 6302; otherwise known as Butterfly Nebula, a star that was once 5 times larger than our sun, is expanding its outer limits. The “wings” are heated to more than 20,000C (36,000F) and sweep across space at more than 600,000mph with a “wingspan” extending over two light years, Nasa scientists said. (Theres something a bit scary about a nebula in space moving at 600,000mph, spans 2 lights years and is heated to 20,000 degrees. Hopefully its expanding towards the other direction, away from earth)
Scientists believe this was also the aftermath between Black Bolt and Vulcan, during the Kree/Shiar war, leaving a giant crack in the middle of space. Really.
