In the depths of space are places both serene and fearsome. In honor of Halloween, here are some glimpses into the dark hearts of the cosmos: nebula - places of destruction, but often also construction. Starbirth alongside star death - the ultimate circle of life. All images are real although colors have been artificially assigned by the research teams in each case.

The Bug Nebula - created by a dying star originally some 5 times the mass of the Sun, now probably less massive than the Sun as it blows itself out into the cosmos. Death was never so beautiful. Credit: NASA, ESA, and the Hubble SM4 ERO Team

Enjoy your spooky celebrations!
