Explanation:
What's happening in the core 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 and orange glows seen mostly in the center of this
highly detailed
featured image.
The blue glow around the edges is
created
primarily
by a trace amount of glowing
oxygen.
Young
and massive stars located in the nebula's center
expel dust when they explode in supernovas.
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.
