According to the data of the study, they found out the central supermassive black hole of NGC 4889 is 5,200 times more massive than the central black hole of the Milky Way, or equivalent to 2.1×1010 (21 billion) solar masses (best fit of data; possible range is from 6 billion to 37 billion solar masses). They have a flattened, unequal distribution that bulges within its edge. The brightest galaxy within the northern Coma Cluster, it is located at a median distance of 94 million parsecs (308 million light years) from Earth. NGC 4889 was not included by the astronomer Charles Messier in his famous Messier catalogue despite being an intrinsically bright object quite close to some Messier objects. The accretion disc sustained the supermassive black hole’s appetite until the nearby supply of galactic material was exhausted.

During its active period, astronomers would have classified NGC 4889 as a quasar and the disc around the supermassive black hole would have emitted up to a thousand times the energy output of the Milky Way. The gamma ray bursts from the galaxy extend out to several million light years of the cluster. Milky Way tips the scales at 1.5 trillion solar masses, Freezing effects of Jupiter’s shadow on Io’s volcanic gases revealed, Astronomers confirm faintest early-universe galaxy ever detected. Astronomers believe that the gigantic black hole has stopped feeding, and is currently resting after feasting on NGC 4889’s cosmic cuisine. A team of scientists has documented atmospheric changes on Io, Jupiter’s volcanically active satellite, as the giant planet casts its shadow over the moon during daily eclipses. ESO 444-46 is a giant elliptical galaxy located about 640 million light-years away in the constellation Centaurus. The Great Diamond, or Diamond of Virgo, is a prominent spring asterism formed by the bright stars Cor Caroli in Canes Venatici constellation, Arcturus in Boötes, Spica in Virgo, and Denebola in Leo. A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter. Do NOT follow this link or you will be banned from the site. This is about 15 times the diameter of Neptune’s orbit from the Sun. The Hubble Space Telescope allowed scientists to capture photos of the galaxy, located in the Coma Cluster about 300 million light-years away. Galaxies range in size from dwarfs with just a few hundred million stars to giants with one hundred trillion stars, each orbiting its galaxy's center of mass. Recently photographed by the Hubble, NGC 4889 is home to a black hole 21 billion times the mass of the sun. The galaxy is surrounded by an immense stellar halo that extends up to one million light-years in diameter. NGC 4478 was discovered by astronomer William Herschel on April 12, 1784. Mai 2020 um 09:59 Uhr bearbeitet. NGC 4478 is an elliptical galaxy located about 50 million light-years away in the constellation Virgo. The egg-like shape of this galaxy is maintained by random orbital motions of its member stars, in contrast to the more orderly rotational motions found in a spiral galaxy such as the Milky Way. The list also includes NGC 4889, which is given the designation Caldwell 35. NGC 4889* is a supermassive black hole with approximately the largest extent made by the Earth, with 37 billion solar masses, making it one of the most massive, and its size can reach the equivalent of 12 orbits of Pluto. A jet of highly energetic plasma extends out to 1,700 light-years from its center. NGC 4889 is located along the high declination region of Coma Berenices, south of the constellation Canes Venatici. NGC 4323 and NGC 4328 are satellite galaxies of M100; the former is connected with it by a bridge of luminous matter. The second-brightest galaxy within the northern Coma Cluster, it is located at a distance of 109 megaparsecs from Earth. The Herschel 400 catalogue is a subset of William Herschel's original Catalogue of Nebulae and Clusters of Stars, selected by Brenda F. Guzman (Branchett), Lydel Guzman, Paul Jones, James Morrison, Peggy Taylor and Sara Saey of the Ancient City Astronomy Club in St. Augustine, Florida, United States c. 1980. As for its large size, NGC 4889 may also be extremely massive. However, as NGC 4889 is a spheroid, and not a flat spiral, it has a three-dimensional profile, so it may be as high as 15 trillion solar masses. Timeline of galaxies, clusters of galaxies, and large-scale structure of the universe. It was discovered by astronomer William Herschel on April 8, 1784. . In December 1995, Patrick Caldwell Moore compiled the Caldwell catalogue, a list of 109 persistent, bright objects that were somehow missed by Messier in his catalogue. Messier 100 is a grand design intermediate spiral galaxy located within the southern part of constellation Coma Berenices. William Herschel discovered this galaxy on October 22, 1835. The galaxy has 18 700 ± 2260 globular clusters. Twenty-one billion times the mass of the Sun, this black hole has an event horizon — the surface at which even light cannot escape its gravitational grasp — with a diameter of approximately 130 billion kilometres. At the core of the galaxy is a supermassive black hole that heats the intracluster medium through the action of friction from infalling gases and dust. Although it is impossible to directly observe a black hole — as light cannot escape its gravitational pull — its mass can be indirectly determined. The galaxy was one of the first spiral galaxies to be discovered, and was listed as one of fourteen spiral nebulae by Lord William Parsons of Rosse in 1850. When it was active, NGC 4889's supermassive black hole was fuelled by the process of hot accretion. This image shows the elliptical galaxy NGC 4889 in front of hundreds of background galaxies, and deeply embedded within the Coma galaxy cluster.

This makes it one of the most massive black holes on record. An elliptical galaxy is a type of galaxy with an approximately ellipsoidal shape and a smooth, nearly featureless image. In addition it has an immense diffuse light halo extending to 17.8 arcminutes, roughly half the angular diameter of the Sun, translating to 1.3 million light years in diameter. Well-hidden from human eyes, there is a gigantic supermassive black hole at the centre of the galaxy. NGC 4478 is a member of the Virgo Cluster. They are one of the three main classes of galaxy described by Edwin Hubble in his Hubble sequence and 1936 work The Realm of the Nebulae, along with spiral and lenticular galaxies. Io’s thin atmosphere collapses as the sulfur dioxide gas emitted from volcanoes freezes when shaded by Jupiter. The atmosphere reforms when Io moves out of eclipse and the ice sublimates. However, under very dark, moonless skies, it can be seen by small telescopes as a faint smudge, but larger telescopes are needed in order to see the galaxy's halo. It has a bright nucleus, an unusually large central bulge, and a prominent dust lane in its inclined disk. As with other similar elliptical galaxies, only a fraction of the mass of NGC 4889 is in the form of stars. NGC 4889 is probably the largest and the most massive galaxy out to the radius of 100 Mpc (326 million light years) of the Milky Way. This heated material also expelled gigantic and very energetic jets. But the time when NGC 4889’s black hole was swallowing stars and devouring dust is past.
