The elliptical galaxy NGC 1132 reveals the final result of what may have been a group of galaxies that merged together in the recent past. Another possibility is that the galaxy formed in isolation as a "lone wolf" in a universe ablaze with galaxy groups and clusters.

Astronomers have spotted small galaxies near the beginning of time that resemble ancestors of our own galactic home. The tiny galaxies are about one-tenth to one-twentieth the size of the Milky Way and have 40 times fewer stars.

Two galaxies perform an intricate dance in this new Hubble Space Telescope image. The galaxies, containing a vast number of stars, swing past each other in a graceful performance choreographed by gravity.

An artificial, laser-fed star now shines regularly over the sky of Paranal, home of ESO's Very Large Telescope, one of the world's most advanced large ground-based telescopes.

Located about 75 million light years away towards the constellation Virgo ('the Virgin'), NGC 5584 is a galaxy slightly smaller than the Milky Way. It belongs, however, to the same category: both are barred spirals.

New data obtained on the apparent celestial couple, NGC 5011 B and C, taken with the 3.6-m ESO telescope, reveal that the two galaxies are not at the same distance, as was believed for the past 23 years.

A pair of interacting galaxies might be experiencing the galactic equivalent of a mid-life crisis. For some reason, the pair, called Arp 82 (see photo), didn't make their stars early on as is typical of most galaxies. Instead, they got a second wind later in life – about 2 billion years ago – and started pumping out waves of new stars as if they were young again.

Astronomers using NASA's Hubble Space Telescope have found that young stellar nurseries, called open star clusters, have very short lives. Hubble gleaned these new observations during a "Where's Waldo" search for blue stars tossed out of their open cluster "nest."

Stephan's Quintet in the constellation Pegasus is a visual grouping of five galaxies which four form the first compact galaxy group ever discovered. The group was discovered by Édouard Stephan in 1877 at Marseilles Observatory and is the most studied of all the compact galaxy groups. NGC 7320, which has extensive H II regions, is the brightest member of the visual grouping and is where active star formation is occurring. Hickson Compact Group 92, which contains four of the five...

Robert's Quartet is four different galaxies in the process of colliding and merging. The galaxies reside in the Phoenix constellation approximately 160 million light-years away. Its members are NGC 87, NGC 88, NGC 89 and NGC 92, discovered by John Herschel in the 1830s. The quartet is one of the best examples of compact groups of galaxies. Since such groups contain four to eight galaxies in a very small area, they provide great laboratories for the study of galactic interactions and their...

Spiral Galaxy -- Among the galaxies, there are apparently three main categories, according to their appearance: the disk galaxies (`cosmic frisbies' according to P. Murdin, D. Allen, and D. Malin), consisting of a huge disk of stars and interstellar matter, which may form interesting patterns, the elliptical galaxies (`cosmic footballs') which are uniformly looking, ellipsoidal agglomerations of stars, and the irregular galaxies (`cosmic misfits') which cannot be integrated in this scheme....

Seyfert's Sextet -- Seyfert's Sextet is a group of galaxies in which gravitational forces are exerted between its members. The galaxies are so tightly packed together that gravitational forces are beginning to rip stars from them and distort their shapes. Those same gravitational forces eventually could bring the galaxies together to form one large galaxy. The name of this grouping, Seyfert's Sextet, implies that six galaxies are participating in the action. But only four galaxies are...

Circinus Galaxy -- Resembling a swirling witch's cauldron of glowing vapors, the black hole-powered core of a nearby active galaxy appears in this colorful NASA Hubble Space Telescope image. The galaxy lies 13 million light-years away in the southern constellation Circinus. This galaxy is designated a type 2 Seyfert, a class of mostly spiral galaxies that have compact centers and are believed to contain massive black holes. Seyfert galaxies are themselves part of a larger class of objects...
