There are about 100,000 stars in this Hubble picture of M72, one of about 200 globular clusters in our Milky Way galaxy. It spans about 50 light years and lies about 50,000 light years away in the constellation Aquarius.

Two stars orbit one another in the core of the large emission nebula NGC 6357 in Scorpius, about 8,000 light-years away from Earth.

One of the last entries in Charles Messier's famous catalog, big, beautiful spiral galaxy M101 is definitely not one of the least. About 170,000 light-years across, this galaxy is enormous, almost twice the size of our own Milky Way Galaxy.

NASA's Fermi Gamma-Ray Space Telescope has unveiled a previously unseen structure centered in the Milky Way. The feature spans 50,000 light-years (roughly half of the Milky Way’s diameter) and may be the remnant of an eruption from a supersized black hole at the center of our galaxy. The structure spans more than half of the visible sky, from the constellation Virgo to the constellation Grus, and it may be millions of years old.


The 6 Most Mind-Blowing Things Ever Discovered in Space

That electrical current was discovered near galaxy 3C303. It's not doing anything that cool ... it's just firing a massive jet of electrified matter 150,000 light-years into outer space. RTh 6 Most Mind-Blowing Things Ever Discovered in Space |

The "Flaming Star" Nebula Lies A Distance Of About 1,500 Light Years, Spans About 5 Light Years & Is Visible With A Small Telescope Toward The Constellation Of The Charioteer (Auriga)

The immense Coalsack Nebula is a molecular cloud in the constellation Crux, about 600 light-years away from Earth. Below it in this image is the Dark Doodad Nebula in the constellation Musca. It is about 700 light-years from Earth. Behind it, about 20,000 light-years from Earth, is the globular star cluster NGC 4372.

The Guardian On 'The Grand Design'

Australian astronomers find the oldest Star: 13.6 billion years old, making it the most ancient star seen. It lies in our own galaxy, the Milky Way, at a distance of around 6,000 light years from Earth. story dated: 10 Feb 2014

3/02/2011: NGC 1499, The California Nebula. Drifting through the Orion Arm of the spiral Milky Way Galaxy, this cosmic cloud echoes the outline of California on the west coast of the United States. Our own Sun also lies within the Milky Way's Orion Arm, only about 1,500 light-years from the California Nebula. The classic emission nebula is around 100 light-years long.

Combined visible and infra-red light images of star forming region Sharpless 2-106. This nebula is located about 2,000 light-years away in the direction of the constellation Cygnus. It is 2 light-years long and 1/2 a light-year across. The central star of this nebula is more than 15 times the mass of our Sun. It formed less 100,000 years ago, making this one of the youngest star-forming regions known.

Arp 227 consists of two galaxies in the constellation Pisces: the large (250,000 light-years across) lenticular galaxy NGC 474 (also known as UGC 864) located about 93 million light-years away, and the spiral galaxy NGC 470 at about 95 million light-years away. They lie at a separation of about 160,000 light-years. - Credit: NASA

LOOK: Vast Star Cluster Shines In High-Res Hubble Telescope Image

Hubble picture of Messier 9 shows hundreds of thousands of stars twice as old as our sun 25,000 light-years away. Wow.

This stellar swarm is M80 (NGC 6093), one of the densest of the 147 known globular star clusters in the Milky Way galaxy. Located about 28,000 light-years from Earth, M80 contains hundreds of thousands of stars, all held together by their mutual gravitational attraction. Globular clusters are particularly useful for studying stellar evolution, since all of the stars in the cluster have the same age (about 15 billion years), but cover a range of stellar masses. Every star visible in this…

A Halo for NGC 6164 Image Credit & Copyright: Don Goldman Explanation: Beautiful emission nebula NGC 6164 was created by a rare, hot, luminous O-type star, some 40 times as massive as the Sun. Seen at the center of the cosmic cloud, the star is a mere 3 to 4 million years old. In another three to four million years the massive star will end its life in a supernova explosion. Spanning around 4 light-years, the nebula itself has a bipolar symmetry.

The Arches Cluster is the densest known star cluster in the Milky Way, and is located about 100 light years distant, in the constellation Sagittarius.

May 2010 M72: A Globular Cluster of Stars Credit: NASA, ESA, Hubble, HPOW Globular clusters once ruled the Milky Way. Back in the old days, back when our Galaxy first formed, perhaps thousands of globular clusters roamed our Galaxy. Today, there are less than 200 left. Pictured above by the Hubble Space Telescope are about 100,000 of M72's stars. M72, which spans about 50 LYrs & lies abt 50,000 LYrs away, can be seen w a small telescope 2ward the constellation of the Water Bearer (Aquarius).

This fantastic skyscape lies near the edge of NGC 2174 - a star forming region about 6,400 light-years away in the nebula-rich constellation of Orion. It follows mountainous clouds of gas and dust carved by winds and radiation from the region's newborn stars, now found scattered in open star clusters embedded around the center of NGC 2174, off the top of the frame.
