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.
