NGC 1700: Elliptical Galaxy and Rotating Disk
16.01.2003

In spiral galaxies, majestic winding arms of young stars and interstellar gas and dust rotate in a disk around a bulging galactic nucleus. Elliptical galaxies seem to be simpler, randomly swarming with old stars and lacking gas and dust.

APOD: 2025 January 29 Б Dust Shells around WR 140 from Webb
29.01.2025

What are those strange rings? Rich in dust, the rings are likely 3D shells -- but how they were created remains a topic of research. Where they were created is well known: in a binary...

APOD: 2020 August 26 Б Cygnus Skyscape
26.08.2020

In brush strokes of interstellar dust and glowing hydrogen gas, this beautiful skyscape is painted across the plane of our Milky Way Galaxy near the northern end of the Great Rift and the constellation Cygnus the Swan.

The Busy Center of the Lagoon Nebula
3.08.2005

Stars are battling gas and dust in the Lagoon Nebula but the photographers are winning. Also known as M8, this photogenic nebula is visible even without binoculars towards the constellation of Sagittarius. The energetic processes of star formation create not only the colors but the chaos.

Celestial Fireworks: Into Star Cluster Westerlund 2
4.07.2017

What if you could go right into a cluster where stars are forming? A one-minute, time-lapse, video visualization of just this has been made with 3D computer modeling of the region surrounding the star cluster Westerlund 2, based on images from the Hubble Space Telescope in visible and infrared light.

APOD: 2025 April 28 Б Gum 37 and the Southern Tadpoles
28.04.2025

This cosmic skyscape features glowing gas and dark dust clouds alongside the young stars of NGC 3572. A beautiful emission nebula and star cluster, it sails far southern skies within the nautical constellation Carina.

Galaxy, Stars, and Dust
12.10.2015

Is this galaxy trapped in a web of dust? No -- it is far in the background. However, spiky stars and spooky shapes are abound in this deep cosmic skyscape. Its well-composed field of view covers about a Full Moon on the sky toward the constellation Pegasus.

The Trifid Nebula in Stars and Dust
13.08.2007

Unspeakable beauty and unimaginable bedlam can be found together in the Trifid Nebula. Also known as M20, this photogenic nebula is visible with good binoculars towards the constellation of Sagittarius. The energetic processes of star formation create not only the colors but the chaos. The red-glowing gas results from high-energy starlight striking interstellar hydrogen gas.
