Nebulae

 

Astronomy Picture of the Day: Red Nebula, Green Comet, Blue Stars

This festively colored skyscape was captured in the early morning hours of December 17, following Comet Wirtanen's closest approach to planet Earth. The comet was just visible to the eye.

Astronomy Picture of the Day: Across Corona Australis

Cosmic dust clouds are draped across a rich field of stars in this broad telescopic panorama near the northern boundary of Corona Australis, the Southern Crown.

Astronomy Picture of the Day: IC 1871: Inside the Soul Nebula

This cosmic close-up looks deep inside the Soul Nebula.

Astronomy Picture of the Day: NGC 1499: The California Nebula

There's even a California in space. Drifting through the Orion Arm of the spiral Milky Way Galaxy, this cosmic cloud by chance echoes the outline of California on the west coast of the United States.

Astronomy Picture of the Day: IC 4592: The Blue Horsehead Reflection Nebula

Do you see the horse's head? What you are seeing is not the famous Horsehead nebula toward Orion but rather a fainter nebula that only takes on a familiar form with deeper imaging.

Astronomy Picture of the Day: IC 59 and IC 63 in Cassiopeia

These bright rims and flowing shapes look ghostly on a cosmic scale.

Astronomy Picture of the Day: Halo of the Cat's Eye

Not a Falcon 9 rocket launch after sunset, the Cat's Eye Nebula (NGC 6543) is one of the best known planetary nebulae in the sky.

Astronomy Picture of the Day: M16: In and Around the Eagle Nebula

From afar, the whole thing looks like an Eagle. A closer look at the Eagle Nebula, however, shows the bright region is actually a window into the center of a larger dark shell of dust.

Astronomy Picture of the Day: NGC 1672: Barred Spiral Galaxy from Hubble

Many spiral galaxies have bars across their centers. Even our own Milky Way Galaxy is thought to have a modest central bar.

Astronomy Picture of the Day: 55 Nights with Saturn

For 55 consecutive nights Mediterranean skies were at least partly clear this summer, from the 1st of July to the 24th of August 2018.
