A new photograph of a distant galaxy looks like it was the inspiration for the 'one ring' in 'The Hobbit,' but it's actually a cosmic phenomenon in which the light from one galaxy is bent into a circle by the gravity of another galaxy.

NASA's Hubble Space Telescope has photographed a number of gas clouds that glow a ghostly green, thanks to radiation blasted out by superpowerful quasars. See the photos in this Hubble photo gallery.

The eight objects betray the past presence of quasars, the most luminous objects in the universe, whose powerful beams of radiation lend the clouds their ethereal glow, researchers said.

Giant winds from black holes can blast gas through galaxies at extraordinary speeds, pulling the plug on star formation, researchers say.

Look southward just after the sky gets dark at this time of year, and you will be sure to see Sirius shining brightly. This is the brightest star in the sky, and marks the eye of the constellation called Canis Major, Latin for "the Large Dog."

The star cluster is unique since it's located thousands of light-years away from the main disc of our galaxy.

The fastest-known star in the Milky Way is on a path out of the galaxy, and new research suggests it was a supernova that gave it the boot.
03 March 2015, 08:47 AM ET
Scientists have found an early galaxy that produces more stars in a single day than the Milky Way creates in a year.

As the calendar shifts into March, skywatchers' ship will really come in. The ship in question is the constellation Argo Navis, which can be seen at around 10 or 11 p.m. local time throughout March, low in the night sky near the southern horizon.

It has long been assumed that the size of a supermassive black hole in a galaxy's core is intimately related to the number of stars that galaxy contains -- but it might not be that simple.
27 February 2015, 07:00 AM ET
A newfound cosmic object may be a long-sought missing link that could help flesh out the black hole family tree. NGC-2276-3c, which lies about 100 million light-years from Earth, appears to be an intermediate-mass black hole.

The European Very Large Telescope's MUSE instrument took a deeper dive into the famous Hubble Deep Field and discovered more galaxies than the Hubble Space Telescope. MUSE data also reveals elements of galactic motion.

Astronomers have just released a brand-new, best-ever 3D view of the deep universe, and it's a doozy.
25 February 2015, 07:00 AM ET
Although these "golden stars" were spotted during a search for an extraterrestrial galactic Internet, the researchers say intelligent aliens have nothing to do with their flickering patterns, as far as they can tell.
20 February 2015, 05:35 PM ET
A strange set of 48 galaxies in the Coma Cluster has very few stars, revealing that these galaxies are especially rich in dark matter. The galaxies may have been robbed of much of their star-forming gas early in their formation, researchers say.

This spectacular space wallpaper shows ESO’s Paranal Observatory in Chile soon after sunset. The last rays of the day create a spectacular orange haze as they pass through the dusty lower levels of the atmosphere, setting a perfect scene.

Explosions on the surface of a dying star may help solve the mystery of the presence of lithium in the galaxy.
18 February 2015, 06:30 AM ET
A spiral galaxy known as NGC 7714 drifted too close to a smaller, neighboring galaxy called NGC 7715. The merger bent both galaxies out of shape.
04 February 2015, 06:00 AM ET
While imaging the Trifid Nebula, Europe’s VISTA infrared telescope peered through our galaxy’s dusty center to reveal two new Cepheid Variable stars. Such stars brighten and fade predictably, giving astronomers a distance measuring tool.
02 February 2015, 03:00 PM ET
One of the least likely places you might think astronomers would learn about ancient supernovae is at the bottom of the ocean but scientists have done just that -- also dredging up a mystery.
28 January 2015, 06:20 PM ET
The stars and constellations seen from Mars would be similar to those seen from Earth, but the Red Planet's two moons would be quite a sight for Martian explorers.
20 January 2015, 04:50 PM ET
Scientists saw repeating pulses from a quasar — a bright galactic core powered by at least one huge black hole — and say the light is likely being generated during the latter stages of a monster black hole collision.
16 January 2015, 12:46 AM ET
This stunning space wallpaper shows a swirling starscape above ESO’s La Silla Observatory. Also, if you look very closely, you can see not one, but three horizontal trails from three separate planes, moving from left to right in the sky.
07 January 2015, 07:10 AM ET
The Lynds Dark Nebula 483 (LDN 483), located 700 light-years away in the constellation Serpens, blocks hundreds of background stars from the view of the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile.
05 January 2015, 06:43 PM ET
In the largest image taken of the galaxy by the space telescope, stars and thousands of star clusters can be seen "embedded in a section of the galaxy’s pancake-shaped disc." The image encompasses over 40,000 light years.

Researchers from the Harvard-Smithsonian Center for Astrophysics (CfA) are developing a 'clock' to decipher stellar age from their spin.

The new image shows "ultra-luminous X-ray sources" (ULXs) studding the spiral galaxies NGC 2207 and IC 2163, which are grazing each other about 130 million light-years from Earth, in the constellation Canis Major.
11 December 2014, 12:47 PM ET
The signal, spotted in the Perseus galaxy cluster and the Andromeda galaxy, corresponds to no known particle or atom and thus may have been produced by dark matter.
