Feeling spacey.
Red glow. Baby stars at the top of this nebula contain radiation that withers away the shape of the cloud over millllllions of years. Why's it red? That would be the hydrogen gas glowing from ultraviolet light.
Colliding galaxies!
The Lagoon Nebula: Many a stars are born here. Stars, like that beaming red one in the corner, tend to blow tunnel shaped clouds of dust. Stardust, as it were.
The Hubble Ultra Deep Field: deepest picture ever taken of the universe. Those bright spots? Yeah, those are galaxies.
Annnnnd I'm spent.
