The Great Nebula in Carina
Explanation: What's happening in the center of the Carina Nebula? Stars are forming, dying, and leaving an impressive tapestry of dark dusty filaments. The entire Carina Nebula , cataloged as NGC 3372, spans over 300 light years and lies about 8,500 light-years away in the constellation of Carina. The nebula is composed predominantly of hydrogen gas, which emits the pervasive red glow seen in this highly detailed featured image . The blue glow in the center is created by a trace amount of glowing oxygen . Young and massive stars located in the nebula's center expel dust when they explode in supernovae. Eta Carinae , the most energetic star in the nebula's center, was one of the brightest stars in the sky in the 1830s, but then faded dramatically .
