APOD: 2025 October 14 Б An Unusual Globule in IC 1396
14.10.2025

Is there a monster in IC 1396? Known to some as the Elephant's Trunk Nebula, parts of gas and dust clouds of this star formation region may appear to take on foreboding forms, some nearly human. The only real monster here, however, is a bright young star too far from Earth to hurt us.

NGC 6823: Cloud Sculpting Star Cluster
8.10.2014

Star cluster NGC 6823 is slowly turning gas clouds into stars. The center of the open cluster, visible on the upper right, formed only about two million years ago and is dominated in brightness by a host of bright young blue stars.

M11: The Wild Duck Cluster
22.01.2003

Many stars like our Sun were formed in open clusters. The above pictured open cluster, M11, contains thousands of stars and is just over five thousand light years distant. The stars in this cluster all formed together about 250 million years ago. The bright young stars in M11 appear blue.

Virgo Cluster Galaxy NGC 4731
29.04.2010

Barred spiral galaxy NGC 4731 lies some 65 million light-years away. The lovely island universe resides in the large Virgo cluster of galaxies. Colors in this well-composed, cosmic portrait, highlight plentiful, young, bluish star clusters along the galaxy's sweeping spiral arms.

The Fox Fur Nebula
14.03.2005

The nebula surrounding bright star S Mon is filled with dark dust and glowing gas. The strange shapes originate from fine interstellar dust reacting in complex ways with the energetic light and hot gas being expelled by the young stars.

A Filament in Monoceros
18.03.2022

Bluish reflection nebulae seem to fill this dusty expanse. The sharp telescopic frame spans over 1 degree on the sky toward the faint but fanciful constellation Monoceros, the Unicorn. Seen within the Monoceros...

Open Cluster M25
31.08.2009

Many stars like our Sun were formed in open clusters. The above pictured open cluster, M25, contains thousands of stars and is about two thousand light years distant. The stars in this cluster all formed together about 90 million years ago. The bright young stars in M25 appear blue.

The Fox Fur Nebula
1.07.2002

The nebula surrounding bright star S Mon is filled with dark dust and glowing gas. The strange shapes that surrounding this star originate from fine interstellar dust reacting in complex ways with the energetic light and hot gas being expelled by the young stars.

Globular Cluster M3
6.12.1996

This huge ball of stars predates our Sun. Long before mankind evolved, before dinosaurs roamed, and even before our Earth existed, ancient globs of stars condensed and orbited a young Milky Way Galaxy.

NGC 206 and the Star Clouds of Andromeda
25.09.2014

The large stellar association cataloged as NGC 206 is nestled within the dusty arms of the neighboring Andromeda galaxy. Also known as M31, the spiral galaxy is a mere 2.5 million light-years away.
