Description

This emission nebula, nicknamed the Heart Nebula, is located 7500 light years away in the constellation of Cassiopeia at a declination of +61 degrees. The nebula spans 1.5 degrees in our apparent view, which corresponds to an actual width of about 180 light years.

This object is a fantastic mix of bright stars, glowing interstellar gas, and dark dust clouds. In the center of the image are the massive hot stars of a newborn star cluster known as Melotte 15. The stellar winds and radiation of these stars are sculpting the surrounding dust clouds into fantastic shapes and pillars.

There are a few other interesting objects here besides IC 1805. At upper right is the Fishhead Nebula (IC1795), which has interestingly shaped dust lanes cutting through the nebula. And at the center left of the image is the small bright blue planetary nebula WeBo1, first discovered in 1996.
