Explanation:
What powers the Heart Nebula?
The large emission nebula dubbed
IC 1805 looks, in whole, like a human heart.
The nebula glows brightly in red light
emitted by its most prominent element:
hydrogen.
The red glow and the larger shape are all created by a
small group of stars near the
nebula's center.
A close up in
high dynamic range (HDR) spanning about 30 light years contains many of these stars is shown above.
This open cluster of stars contains a few
bright stars nearly 50 times the mass of our Sun,
many dim stars only a fraction of the mass of our Sun, and an
absent microquasar
that was expelled millions of years ago.
The Heart Nebula is located about 7,500 light years away toward the
constellation of Cassiopeia.
