APOD 1.3

LL pegasi

the spiral in the image is from two stars orbiting each other, forming a nebula as they cast off their atmospheres. 800 years for two stars to orbit each other. more than eight lifetimes to complete a circle. Circles that will continue to be repeated for billions of years. Aren't we tiny? And that Spiral is just a third of a light year, when the closet star other than our own sun is a couple light years.
