Galaxy NGC 17 in the Whale - Galaxy NGC 17 in Cetus - The galaxy NGC 17 is located about 250 million years away from Earth. Presented with a single nucleus, its shape indicates that it has finished absorbing another galaxy. Image obtained by the Hubble Space Telescope on 4 July 2002. This galaxy features a single nucleus, a containing a blue central disk with delicate fine structure in the outer parts and tidal tails indicative of two former disk galaxies. At present these galaxies appear to have completed their merger. The remnant shows clear signs that the merger was gas - rich and accompanied by a starburst. NGC 17 is gas - rich and can sustain its strong central starburst and present mild central activity for some time to come. NGC 17 is located about 250 million light - years away in the constellation of Cetus, the Whale. Image taken by the Hubble space telescope on july 4, 2002

Galaxy cluster Abell 1689 - Gravitational lenses in Abell 1689 galaxy cluster - Galaxy cluster Abell 1689 is about 2.2 billion years ago - light in the constellation of the Virgin. This image shows, by a gravitational mirage effect, the deformed image of many galaxies located behind the cluster. Near infrared and visible image obtained by the Hubble space telescope in June 2002. 13 hours of installation. This representative color image is a composite of visible - light and near - infrared exposures taken in June 2002. Hubble peered straight through the center of one of the most massive galaxy clusters known, called Abell 1689. This required that Hubble gaze at the remote cluster, located 2.2 billion light - years away, for over 13 hours. The gravity of the cluster's trillion stars - - plus dark matter - - acts as a 2 - million - light - year - wide “” lens”” in space. This “” gravitational lens””” bends and magnifies the light of galaxies located far behind it. Although much more analy

Spiral galaxy NGC 5584 - Spiral galaxy NGC 5584 - NGC 5584 is located 72 million light years from Earth in the constellation Virgin. This galaxy is home to many Cepheides, variable stars used to accurately measure distances in the universe and calculate the rate of expansion of the universe. Image obtained by the Hubble Space Telescope. The brilliant, blue glow of young stars traces the graceful spiral arms of galaxy NGC 5584 in this Hubble Space Telescope image. Thin, dark dust lanes appear to be flowing from the yellowish core, where older stars reside. The reddish dots sprinkled throughout the image are largely background galaxies. Among the galaxy's myriad stars are pulsating stars called Cepheid variables and one recent Type Ia supernova, a special class of exploding stars. Astronomers use Cepheid variables and Type Ia supernovae as reliable distance markers to measure the university's expansion rate. NGC 5584 was one of eight galaxies astronomers studied to measure the university

Spiral galaxy NGC 3370 in the Lion - Spiral galaxy NGC 3370 in Leo - The spiral galaxy NGC 3370 is located about 100 million years away - light from Earth. In November 1994, light emitting from a supernova type Ia, SN 1994ae, part of this galaxy, reached Earth. In this image taken by the Hubble space telescope in May 2003, this supernova is no longer detectable.

The collision, seen here about 100 million years later, caused intense star flames. Image obtained by the Hubble Space Telescope on 15 March 1999. NGC 6621/2 (VV 247, Arp 81) is a strongly interacting pair of galaxies, seen about 100 million years after their closest approach. It consists of NGC 6621 (to the left) and NGC 6622 (to the right). NGC 6621 is the larger of the two, and is a very disturbed spiral galaxy. The encounter has pulled a long tail out of NGC 6621 that has now wrapped behind its body. The collision has also triggered extensive star formation between the two galaxies. Scientists believe that Arp 81 has a richer collection of young massive star clusters than the notable Antennae

Spiral galaxies NGC 3314 A and B in Hydra - Galaxy pair NGC 3314 in Hydra - NGC 3314 is a pair of spiral galaxies distant about 140 million years - Earth light. These galaxies are not interacting but just perfectly aligned in front of each other from Earth. Nasa's Hubble Space Telescope shows a rare view of a pair of overlapping galaxies, called NGC 3314. The two galaxies look as if they are colliding, but they are actually separated by tens of millions of light - years, or about ten times the distance between our Milky Way and the neighboring Andromeda galaxy. The chance alignment of the two galaxies, as seen from Earth, gives a unique look at the silhouetted spiral arms in the closer face - on spiral, NGC 3314A. The motion of the two galaxies indicates that they are both relatively undisturbed and that they are moving in markedly different directions. The color composite was produced from exposures taken in blue and red light with Hubble's Advanced Camera for Surveys. The pair of gal

Spiral Galaxy NGC 2397 - Galaxy Spiral NGC 2397 - The galaxy NGC 2397 is a classic spiral galaxy located about 60 million years ago - light from Earth in the southern constellation of Flying Fish. The central part houses old yellow and red stars while new stars form in the outer arms. This image obtained by the space telescope on 14 October 2006 shows the brightest of these young blue stars. The 2006bc supernova, which exploded in March 2006, is also visible near the central region, while its lightning shrinking. Located nearly 60 million light - years away from Earth, the galaxy NGC 2397 is typical of most spirals, with mostly older, yellow and red stars in its central portion, while star formation continues in the outer, bluer spiral arms. The brightest of these young, blue stars can be seen individually in this high resolution view from the Hubble's Advanced Camera for Surveys (ACS). One typical feature of this Hubble image is the view of supernova SN 2006bc taken when its brightnes

Elliptical galaxy NGC 1316 in the Furnace - Giant elliptical galaxy NGC 1316 - By studying the clusters of stars and clouds of dust visible in this photo taken by the Hubble space telescope in March 2003, it is believed that the giant elliptical galaxy NGC 1316 is the result of a collision of two spiral galaxies that occurred some billions of years ago. This galaxy resides about 75 million light years ago in the cluster of galaxies of the Furnace. Also called Fornax A, it is one of the strongest radio sources in the sky. This image made from data obtained with the NASA Hubble Space Telescope reveals the dust lanes and star clusters of this giant galaxy that give evidence that it was formed from a past merger of two gas - rich galaxies. NGC 1316 is on the outskirts of a nearby cluster of galaxies in the southern constellation of Fornax, at a distance of about 75 million light - years.

Star field in the halo of the Andromede galaxy - Deep field image in the halo of Andromeda galaxy - Deep field in the halo of the Andromede galaxy obtained by the Hubble space telescope in 2003. 300,000 stars as well as thousands of background galaxies are visible. Astronomers using Nasa's Hubble Space Telescope (HST) have reliably measured the age of the spherical halo of stars surrounding the neighboring Andromeda galaxy (M31). To their surprise, they have discovered that approximately one - third of the stars in Andromeda's halo formed only 6 to 8 billion years ago. That's a far cry from the 11 - to - 13 billion - year age of the stars in the Milky Way's halo. Why the difference in halo ages? Apparently, M31 must have gone through a major “” corporate merger”” with another large galaxy, or a series of mergers with smaller galaxies, billions of years ago. Astronomers cannot yet tell whether this was one tumultuous event or a more continual acquisition of smaller galaxies. The newly d

Interacting galaxies NGC 454 - Interacting galaxies NGC 454 - NGC 454 is located about 164 million light years away from Earth in the southern constellation of Phenix. This pair of interacting galaxies consists of a large elliptical galaxy and an irregular galaxy. The fusion process between the two galaxies is still in its early stages and no sign of star formation caused by this interaction has been detected. Image obtained by the Hubble Space Telescope on 6 March 1997. NGC 454 is galaxy pair comprising a large red elliptical galaxy and an irregular gas - rich blue galaxy. The system is in the early stages of an interaction that has severely distorted both components. The three bright blue knots of very young stars to the left of the two main components are probably part of the irregular blue galaxy. Although the dust lanes that stretch all the way to the center of the elliptical galaxy suggest that gas has penetrated that far, no signs of star formation or nuclear activity are visibl
