Interacting Galaxies Arp 240 - Interacting galaxies Arp 240 - The galaxy Arp 240 is located about 300 million light years away from Earth in the constellation of the Virgin. Composed of spiral galaxies NGC 5257 and NGC 5258, this interacting system presents important star formations. The two galaxies contain a supermassive black hole in the centre. Image obtained by the Hubble Space Telescope on 20 December 2001. NGC 5257/8 (Arp 240) is an astonishing galaxy pair, composed of spiral galaxies of similar mass and size, NGC 5257 and NGC 5258. The galaxies are visibly interacting with each other via a bridge of dim stars connecting the two galaxies, almost like two dancers holding hands while performing a pirouette. Both galaxies harbor supermassive black holes in their centers and are actively forming new stars in their disks. Arp 240 is located in the constellation Virgo, approximately 300 million light - years away, and is the 240th galaxy in ARP's Atlas of Peculiar Galaxies. With the e

The Sculptor dwarf galaxy is one of our Milky Way's neighbouring dwarf galaxies. The Milky Way is, like all large galaxies, thought to have formed from smaller galaxies in the early days of the Universe. These small galaxies should also contain many very old stars, just as the Milky Way does, and a team of astronomers has now shown that this is indeed the case.

Galaxies NGC 5426 and NGC 5427 in the Virgin - Galaxies NGC 5426 and NGC 5427 in Virgo - Arp 271 desks the two spiral galaxies of similar sizes in interaction NGC 5426 and NGC 5427. Located 90 million years ago - light in the constellation of Virgo, Arp 271 is about 130,000 years - light in diameter. Although it is uncertain whether this interaction leads to a fusion of galaxies, the galaxies are already gravitationally affected by each other and a bridge of matter has formed between the two. Image obtained with a telescope of 80 cm. NGC 5426 and NGC 5427 are two spiral galaxies of similar sizes engaged in a dramatic dance. It is not certain that this interaction will end in a collision and ultimately a merging of the two galaxies, although the galaxies have already been affected. Together known as Arp 271, this dance will last for tens of millions of years, creating new stars as a result of the mutual gravitational attraction between the galaxies, a pull seen in the bridge of stars al

Center of the Andromede Galaxy (M31) - Center of the Andromeda galaxy - The Andromede galaxy is located about 2 million years ago - light from Earth. Two satellite galaxies accompany it: M32 (NGC 221) on the left and M110 (NGC 205) (off-field). Like the lactee path, the Andromede galaxy belongs to the local group, making up about thirty galaxies. Andromeda is the nearest major galaxy to our own Milky Way Galaxy. Our Galaxy is thought to look much like Andromeda. Together these two galaxies dominate the Local Group of galaxies. The diffuse light from Andromeda is caused by the hundreds of billions of stars that compose it. The several distinct stars that surround Andromeda's image are actually stars in our Galaxy that are well in front of the background object. M31 is so distant it takes about two million years for light to reach us from there. Much about M31 remains unknown, including how the center acquired two nuclei

Galaxy System Arp 274 - Galaxy triplet Arp 274 - Arp 274 (NGC 5679) is a system of three galaxies located about 400 million years ago - light in the constellation of Virgo. Image obtained by the Hubble Space Telescope. Arp 274, also known as NGC 5679, is a system of three galaxies that appear to be partially overlapping in the image, although they may be at somewhat different distances. The spiral shapes of two of these galaxies appear mostly intact. The third galaxy (to the far left) is more compact, but shows evidence of star formation. Two of the three galaxies are forming new stars at a high rate. This is evident in the bright blue knots of star formation that are strung along the arms of the galaxy on the right and along the small galaxy on the left. The largest component is located in the middle of the three. It appears as a spiral galaxy, which may be barred.

Colliding spiral galaxies NGC 2207 and IC 2163 - Colliding galaxies NGC 2207 and IC 2163 - The galaxies NGC 2207 (left) and IC 2163 (right) form a pair of colliding galaxies approximately 114 million light years away. Currently IC 2163 is moving away from NGC 2207, but it is likely that within several billion years these two galaxies will eventually merge into a single massive galaxy. Image obtained by the Hubble Space Telescope in 1998. The larger and more massive galaxy is cataloged as NGC 2207 (on the left in the Hubble Heritage image), and the smaller one on the right is IC 2163. Strong tidal forces from NGC 2207 have distorted the shape of IC 2163, flinging out stars and gas into long streamers stretching out a hundred thousand light - years towards the right - hand edge of the image. The calculations indicate that IC 2163 is swinging past NGC 2207 in a counterclockwise direction, having made its closest approach 40 million years ago. However, IC 2163 does not have sufficient ener

Collision galaxy NGC 520 - Galaxy NGC 520 in Pisces - The galaxy NGC 520, is about 100 million light years away from Earth in the constellation Pisces. This system consists of two colliding galaxies. The merger started 300 million years ago. The two galaxies are only in the middle of this process, their disk having merged but not yet their kernel. NGC 520 is among the brightest pairs of galaxies, and is visible with a small telescope. Image obtained by the Hubble Space Telescope on October 22, 2004. NGC 520 is the product of a collision between two disk galaxies that started 300 million years ago. It examplifies the middle stages of the merging process: the disks of the parent galaxies have merged together, but the nuclei have not yet coalesced. It features an odd - looking tail of stars and a prominent dust lane that runs diagonally across the center of the image and obscures the galaxy. NGC 520 is one of the brightest galaxy pairs on the sky, and can be observed with a small telescop

Spiral Galaxy NGC 253 in Sculptor - Spiral galaxy NGC 253 in Sculptor - NGC 253 is the brightest galaxy of the Sculptor's group, the closest galaxy group to the Local Group. It is about 10 million light years away. Image made with Siding Spring's 3.9m telescope in 1975. A mere 10 million light years away, NGC 253 is one of the nearest spiral galaxies, a member of a small group straggling across the southern constellation of Sculptor. It appears elongated because we see it almost edge - on. This galaxy is also one of the dustiest galaxies known and much of its internal detail is hidden by obscuring matter which can be seen as dark patches against the background stars. Despite the obscuration, two spiral arms and many bluish clusters of stars can be seen around the edge of the galaxy. NGC 253 is so close to us that some of the brightest stars are apparent as individuals within the spiral arms
