PIX4611992: Elliptical galaxy NGC 4881 and distant galaxies - Elliptical galaxy NGC 4881 and distant galaxies - The elliptical galaxy NGC 4881 (upper left) is about 300 million years away - light from Earth. NGC 4881 is located in the Coma galaxy cluster that contains at least 1,000 galaxies and is five times farther from us than the Virgin's cluster. Almost all the objects visible in this photo are located far behind the Coma cluster, except for the spiral galaxy to the right of Ngc 4881. Image obtained by the Hubble Space Telescope in 1994. This photo mosaic, which shows a field of distant galaxies, is a computer enhanced reproduction of a picture taken 4 March 1994 with the repaired Hubble Space Telescope. The brightest object in this picture is NGC 4881. It is a 13th - magnitude elliptical galaxy in the outskirts of the Coma Cluster, a great cluster of galaxies more than 5 times farther away than the Virgo Cluster. Except for a 16th - magnitude Coma spiral at the right and a few foreground stars of the Milky Way, almost everything else in this field lies far beyond the Coma Cluster. There is a fascinating assortment of background galaxies, including an apparent galaxian merger in progress / Bridgeman Images

Image obtained from different cliches obtained from 2006 to 2009, 28 hours of installation in total. A long - exposure Hubble Space Telescope image shows a majestic face - on spiral galaxy located deep within the Coma Cluster of galaxies, which lies 320 million light - years away in the northern constellation Coma Berenices. The galaxy, known as NGC 4911, contains rich lanes of dust and gas near its center. These are silhouetted against glowing newborn star clusters and iridescent pink clouds of hydrogen, the existence of which indicates ongoing star formation. Hubble has also captured the outer spiral arms of NGC 4911, along with thousands of other galaxies of varying sizes. This natural - color Hubble image, which combines data obtained in 2006, 2007, and 2009 from the Wide Field Planetary Camera 2 and the Advanced Camera for Surveys, required 28 hours of exposure time / Bridgeman Images

PIX4612079: Spiral Galaxy NGC 4921 - Unusual Spiral NGC 4921 in the Coma Galaxy Cluster - Galaxy NGC 4921 photographed by the Hubble Space Telescope (HST). Located in the cluster of Coma galaxies (Abell 1656) is about 320 million light years old, this spiral galaxy presents an unusual structure with poorly marked arms; some young blue stars are visible but the activity of star formation here is much less strong than in other spiral galaxies. In the background, many more distant galaxies appear. This very deep image taken with the NASA/ESA Hubble Space Telescope shows the spiral galaxy NGC 4921 along with a spectacular backdrop of more distant galaxies. It was created from a total of 80 separate pictures through yellow and near - infrared filters. The Coma Galaxy Cluster, in the northern constellation of Coma Berenices, the hair of Queen Berenice, is one of the closest very rich collections of galaxies in the nearby Universe. The cluster, also known as Abell 1656, is about 320 million light - years from Earth and contains more than 1000 members. The brightest galaxies, including NGC 4921 shown here, were discovered back in the late 18th century by William Herschel. The galaxies in rich clusters undergo many interactions and mergers that tend to gradually turn gas - rich spirals into elliptical systems without much active star formation. As a result there are far more ellipticals and fewer spirals in the Coma Cluster than are found in quieter corners of the Universe. NGC 4921 is one of the rare spirals in Coma, and a rather unusual one - - it is an example of an “” anaemic spiral”” where the normal vigorous star formation that creates a spiral galaxy's familiar bright arms is much less intense. As a result there is just a delicate swirl of dust in a ring around the galaxy, accompanied by some bright young blue stars that are clearly separated out by Hubble's sharp vision.
