Shot from one of my favorite websites, Astronomy Picture of the Day.
This is a Hubble shot of the Lagoon Nebula from 1995. A fantastic shot of dust and gas lit by the young stars you can barely see through the dust. A shot of almost every colors of the palate. The nebula lies about 5,000 light years away in the constellation Sagitarius.
It's almost an impressionist painting. I could get lost in this for hours.
