PIX4611595: Spiral galaxy of the Sombrero M104 infrared view - Sombrero galaxy seen in infrared - Infrared image of the spiral galaxy M104 (Sombrero galaxy), located about 28 million years ago - light, obtained with the Spitzer space telescope in 2004 and January 2005. Infrared radiation shows the dust of the disc visible throughout the circumference. A high emission also comes from the center of the galaxy where a supermassive black hole is thought to reside there. This spiral galaxy is located some 28 million light - years away. The infrared image obtained by Spitzer space telescope in 2004 and 2005 pierces through the obscuring dust, along with the bulge of stars. It shows that the disk is warped, which is often the result of a gravitational encounter with another galaxy; clumpy areas spotted in the far edges of the ring indicate young star - forming regions. Spitzer detected infrared emission not only from the ring, but from the center of the galaxy too, where there is a huge black hole, believed to be a billion times more massive than our Sun / Bridgeman Images
PIX4611598: Spiral galaxy of Sombrero M104 in the Virgin - The Sombrero galaxy (M104) in Virgo - The spiral galaxy M104 (NGC 4594, Sombrero galaxy) is located about 28 million years ago - light. Image obtained with the ANTU telescope of the VLT on January 30, 2000. The light from this remarkable spiral system is dominated by the billions of old, faint stars that form the vast 'bulge' around its tiny hidden nucleus. Most spirals, including the Milky Way, have clouds of old, faint stars around their nuclei, but in M104 the galaxy's light is dominated by them. This effect is enhanced because disk of the galaxy is seen nearly edge - on and dust in its outer parts is in silhouette as it crosses the picture. The galaxy is about 28 million light years distant. This image was obtained with FORS1 instrument on ANTU telescope at Paranal observatory on January 30 2000 / Bridgeman Images

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
PIX4612005: Spiral Galaxy NGC 4911 - Galaxy Spiral NGC 4911 - The NGC 4911 galaxy photographed here by the Hubble Space Telescope (HST) is located in the Coma galaxy cluster (Abell 1656) about 320 million light years ago. 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.

PIX4612157: Centaurus A Elliptical Galaxy (NGC 5128) in the Centaur - Galaxy Centaurus A - The NGC 5128 galaxy is about 13 million years away - light from Earth. This image obtained by the Hubble Space Telescope in 1998 shows the star flames that occur in the dark band of the galaxy. In blue, these are the clusters of newly shaped young stars. At the top left, a photo of the galaxy obtained from the ground. This giant galaxy is a powerful radio source known as Centaurus A. It is an active galaxy whose energy comes from a supermassive black hole. NGC 5128 is the nearest large elliptical galaxies to our sun. It is also the nearest of the giant radio galaxies, possessing an active galactic nucleus (AGN) and optically one of the most luminous galaxies in the sky. Among many other things NGC 5128 is also the prototypical postmerger elliptical galaxy. Structural peculiarities including the prominent rotating disk of stars and gas and the complex shell structure of its halo point to a large scale merger within the last billion years. Tidal streams of young stars have also been identified in the halo of NGC 5128 thought to have occurred by cannibalization of a nearby gas rich dwarf galaxy some 300 million years ago, long after the large scale merger. Elliptical galaxies are typically devoid of gas, dust and young stars. The unexpected presence of gas rich disk elements within the structure of NGC 5128 supports the current belief that accretions and mergers of low mass galaxies may be an important agent in the evolution of galaxy formation. As a radio galaxy, NGC 5128 belongs to the subgroup of galaxies called Active Galaxies, which include Quasars, Seyfert galaxies, Blazars and Radio Galaxies. Active galaxies are distinguished by their prodigious energy output which cannot be explained by their stellar populations and must have another source. Active galaxies have in common an “Active Galactic Nucleus (AGN)”” which is beli / Bridgeman Images
