Stars are forming, dying, and leaving an impressive tapestry [5] of dark dusty filaments. The entire Carina Nebula [6] , cataloged as NGC 3372, spans over 300 light years [7] and lies about 8,500 light-years away in the constellation [8] of Carina. The nebula is composed predominantly of hydrogen [9] gas, which emits the pervasive red glow [10] seen in this highly detailed featured image [11] . The blue glow in the center is created by a trace amount of glowing oxygen [12] . Young and massive stars located in the nebula's center expel dust [13] when they explode in supernovae. Eta Carinae [14] , 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 [15] .
