ScienceDaily. These velocities -- which depend on the mass of the object they orbit -- revealed the immense mass of the supermassive black hole. ngc 4884 • ugc 8110 • mcg 5-31-77 • pgc 44715 • zwg 160.241 • drcg 27-148 Az NGC 4889 (más néven Caldwell 35 ) egy elliptikus galaxis a Coma Berenices (Bereniké haja) csillagképben . Questions? The asterism shares the stars Arcturus and Spica with the Spring Triangle, an asterism formed by these two stars with Regulus, the … [Read more…]. So how big is it, exactly? Well, according to our best estimates, the supermassive black hole is roughly 21 billion times the size of the Sun, and its event horizon (an area so dense and powerful that light can’t escape its gravity) measures 130 billion kilometers in diameter.

Now, napping quietly as it waits for its next celestial snack, the supermassive black hole is dormant. But the elliptical galaxy, pictured in this new image from the NASA/ESA Hubble Space Telescope, harbours a dark secret.
During its active period, astronomers would have classified NGC 4889 as a quasarand the disc around the supermassive black hole would have emitted up to a thousand times the energy output of the Milky Way. TL;DR — About 2.8 light-days. “The accretion disk sustained the supermassive black hole’s appetite until the nearby supply of galactic material was exhausted. Now, napping quietly as it waits for its next celestial snack, the supermassive black hole is dormant”, says the Hubble Space Telescope website. The placid appearance of NGC 4889 can fool the unsuspecting observer. 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. But the elliptical galaxy, seen in a new image from the NASA/ESA Hubble Space Telescope, harbors a … ESA/Hubble Information Centre.

It was discovered in 1785 by the British astronomer Frederick William Herschel. When it was active, NGC 4889's supermassive black hole was fuelled by the process of hot accretion. Although it is impossible to directly observe a black hole -- as light cannot escape its gravitational pull -- its mass can be indirectly determined. For this particular black hole in the NGC 4889 galaxy, scientists used instruments on the Keck II Observatory and the Gemini North Telescope to measure the velocity of stars moving around the center point of the galaxy.

"The sleeping giant NGC 4889 harbors a dark secret." But the black hole is now in dormant mode because there isn’t any more sustenance stored in the orbiting accretion disk.
That’s about 15 times the diameter of Neptune’s orbit around the Sun, according to scientists at the Hubble Space Telescope. 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. ScienceDaily shares links with sites in the.
But the time when NGC 4889's black hole was swallowing stars and devouring dust is past.
Space stuff like gases, dust, and galactic debris fell towards the black hole and created an accretion disk. NGC 4889 Great Diamond.

Located about 300 million light-years away in the Coma Cluster, the giant elliptical galaxy NGC 4889, the brightest and largest galaxy in this image, is home to a record-breaking supermassive black hole. Orbiting the black hole, this spinning disc of material was accelerated by the black hole's immense gravitational pull and heated to millions of degrees. Have any problems using the site?
