Young Hot Stars, Beautiful and Deadly, Will Kill Their Mother Nebula | Video
A star-forming cloud of gas and dust named Gum 15 will eventually be destroyed by its offspring. The La Silla Observatory in Chile observed this future cosmic crime scene in the Vela constellation. The red glow comes from ionized hydrogen.
Once past their infant stages, these stars will generate winds strong enough to break up the gas around them. When the most massive of these stars run out of fuel and explode, they will take the Gum 15 nebula with them. The image, from the Wide Field Imager on the MPG/ESO 2.2-metre telescope, is one of ESO's Cosmic Gems program targets.
