| Description: | The
Crescent nebula is located in the constellation of Cygnus. It's about 4,000
light years away and spans the area of 15 by 10 light years. The nebula
was created by its central star shedding its outer envelope at a rate of one solar mass every 10,000 years. This creates a strong stellar
wind that's visible in the wave front compression at the edges of the
nebula. Crescent is a part of a larger diffuse nebula IC1318 visible as dim red clouds around and below it in the picture. |
