Hydrogen in M51, NGC 5194. Perhaps the first spiral nebula, M51 is a large galaxy, over 60,000 ly across, with a readily apparent spiral structure. M51 is a part of a well-known interacting galaxy pair, its spiral arms and and dust lanes clearly sweeping in front of companion galaxy NGC 5195 (top).
The ring-like swirls of dust filling the Andromeda galaxy stand out colorfully in this new image from the Herschel Space Observatory, a European Space Agency mission with important NASA participation. The glow seen here comes from the longer-wavelength, or far, end of the infrared spectrum, giving astronomers the chance to identify the very coldest dust in our galactic neighbor.

Hubble Observes Glowing, Fiery Shells of Gas It may look like something from "The Lord of the Rings," but this fiery swirl is actually a planetary nebula known as ESO 456-67. Set against a backdrop of bright stars, the rust-colored object lies in the constellation of Sagittarius (The Archer), in the southern sky.

Animated Flight Through the Universe. The Third Sloan Digital Sky Survey (SDSS-III) has issued Data Release 9 (DR9), the first public release of data from the Baryon Oscillation Spectroscopic Survey (BOSS). In this release BOSS, the largest of SDSS-III's four surveys, provides spectra for 535,995 newly observed galaxies, 102,100 quasars, and 116,474 stars, plus new information about objects in previous Sloan surveys (SDSS-I and II).

This Hubble Space Telescope (HST) image reveals a pair of one-half light-year long interstellar twisters - eerie funnels and twisted-rope structures - in the heart of the Lagoon Nebula (Messier 8) which lies 5,000 light-years away in the direction of the constellation Sagittarius.

Carina Nebula (ground-based image) Click to Enlarge This image shows a giant star-forming region in the southern sky known as the Carina Nebula and combines the light from three different filters, which traces emission from oxygen (blue), hydrogen (green), and sulfur (red).
This Hubble image of the Antennae galaxies is the sharpest yet of this merging pair of galaxies. As the two galaxies smash together, billions of stars are born, mostly in groups and clusters of stars. The brightest and most compact of these are called super star clusters
Art imitates nature A new picture from the NASA/Space Telescope bears remarkable similarities to the van Gogh work, complete with never-before-seen spirals of dust swirling across trillions of kilometres of interstellar space. This image, obtained with the Advanced Camera NASA, latest view of an expanding halo of light around a distant star. The illumination of interstellar dust comes from the red supergiant star at the middle of the image. Manija, sashi, Sonja.
