APOD: 2026 July 22 Б The Corona Australis Cloud and the Chandelier Cluster
22.07.2026

The Southern Crown (Corona Australis) dazzles with young and ancient celestial jewels. The Corona Australis Cloud is a collage of reflection and emission nebulae on the left of todayБs image. At 430 light years away, this cloud is one of the closest star-forming regions to Earth.

NGC 253: Dusty Island Universe
6.11.2025

Shiny NGC 253 is one of the brightest spiral galaxies visible, and also one of the dustiest. Some call it the Silver Coin Galaxy for its appearance in small telescopes, or just the Sculptor Galaxy for its location within the boundaries of the southern constellation Sculptor.

Lunar Dust and Duct Tape
17.04.2004

Why is the Moon dusty? On Earth, rocks are weathered by wind and water, creating soil and sand. On the Moon, the long history of micrometeorite bombardment has blasted away at the rocky surface creating a layer of powdery lunar soil or regolith. This lunar regolith could be a scientific and industrial bonanza.

Our Dusty Universe
19.11.2000

What's black & white and red all over? Add our universe to this list. Adrift in a vast sea of darkness are not only familiar bright stars but dust that glows predominantly in far-infrared light.

Starlight Reflections
14.04.1998

Wisps of dust fill the space between the stars. This dust is usually invisible, subtly acting to dim the light of more distant stars. Sometimes this dust is thick and prominent as dark patches on otherwise bright emission nebulae. Other times this dust may show itself by reflecting the light of bright, nearby stars.

APOD: 2007 February 23- Dust and the Helix Nebula
23.02.2007

Dust makes this cosmic eye look red. The eerie Spitzer Space Telescope image shows infrared radiation from the well-studied Helix Nebula (NGC 7293) a mere 700 light-years away in the constellation Aquarius.

LDN 1622: Dark Nebula in Orion
11.05.2007

The silhouette of an intriguing dark nebula inhabits this cosmic scene, based on images from the Palomar Observatory Sky Survey. Lynds' Dark Nebula (LDN) 1622 appears against a faint background of glowing hydrogen gas only easily seen in long telescopic exposures of the region.

The Reflecting Dust Clouds of Orion
21.01.2003

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 Pleiades Deep and Dusty
25.02.2014

The well known Pleiades star cluster is slowly destroying part of a passing cloud of gas and dust. The Pleiades is the brightest open cluster of stars on Earth's sky and can be seen from almost any northerly location with the unaided eye.
