A Close-Up of the Lagoon Nebula
20.08.1996

Ribbons of red-glowing gas and dark dust surround massive young stars in this close-up of the Lagoon Nebula taken by the Hubble Space Telescope. The Lagoon Nebula is relatively close and bright - it appears larger than the Full Moon and is visible even without a telescope.

The Reflecting Dust Clouds of Orion
20.01.2003

In the vast Orion Molecular Cloud complex, several bright blue nebula are particularly apparent. Pictured above are two of the most prominent reflection nebulas -- dust clouds lit by the reflecting light of bright-embedded stars. The more famous nebula is M78, on the upper right, cataloged over 200 years ago.

The North America Nebula
6.06.1996

Here's a familiar shape in an unfamiliar location! This emission nebula is famous partly because it resembles Earth's North American Continent. To the right of the North America Nebula is a less luminous Pelican Nebula. Let's be grateful that pelicans aren't really that large!

Recycling Cassiopeia A
12.07.2002

For billions of years, massive stars in our Milky Way Galaxy have lived spectacular lives. Collapsing from vast cosmic clouds, their nuclear furnaces ignite and create heavy elements in their cores. After a few million years, the enriched material is blasted back into interstellar space where star formation begins anew.

Cosmic Tornado HH 49 50
2.02.2006

Light-years in length, this cosmic tornado is actually a powerful jet cataloged as HH (Herbig-Haro) 49/50 blasting down from the top of a Spitzer Space Telescope view. Though such energetic outflows are well known...

Dark Clouds of the Carina Nebula
19.09.2010

What dark forms lurk in the mists of the Carina Nebula? These ominous figures are actually molecular clouds, knots of molecular gas and dust so thick they have become opaque. In comparison, however, these clouds are typically much less dense than Earth's atmosphere.

Young Suns of NGC 7129
27.10.2011

Young suns still lie within dusty NGC 7129, some 3,000 light-years away toward the royal constellation Cepheus. While these stars are at a relatively tender age, only a few million years old, it is likely that our own Sun formed in a similar stellar nursery some five billion years ago.

The Light, the Dark, and the Dusty
10.06.2015

This colorful skyscape spans about three full moons (1.5 degrees) across nebula rich starfields along the plane of our Milky Way Galaxy in the royal northern constellation Cepheus. Near the edge of the region...

Pan STARRS Across the Lagoon
24.04.2019

Ridges of glowing interstellar gas and dark dust clouds inhabit the turbulent, cosmic depths of the Lagoon Nebula. Also known as M8, the bright star forming region is about 5,000 light-years distant.

APOD: 2020 August 14 Б NGC 5189: An Unusually Complex Planetary Nebula
13.08.2020

Why is this nebula so complex? When a star like our Sun is dying, it will cast off its outer layers, usually into a simple overall shape. Sometimes this shape is a sphere, sometimes a double lobe, and sometimes a ring or a helix.
