messier 87


The red region is about 1/10 light-year across. The images are part of a time-lapse movie that reveals changes in the jet from 1995 to 2007. Messier 87 (M87), also known as Virgo A or the Smoking Gun, is a supergiant elliptical galaxy located in the core of the Virgo Cluster, in the southern constellation Virgo. The source was identified as M87 by 1953, with the relativistic jet emanating from the galaxy’s core suggested as a likely cause. values go up to 15,000, e.g. Andromeda galaxy M31. Messier 26 amzn_assoc_region = "US";

investigation with the Hubble Space Telescope. The galaxy has a jet of energetic plasma emanating from its core and extending at least 4,900 light years outwards. These images are part of a new time-lapse movie that shows hot plasma spiraling along magnetic field lines generated by the supermassive black hole.

Globular Cluster Systems list), surrounding this giant galaxy in a A curious straight ray lies in a gap in the nebulosity in p.a. interactions with other Virgo Cluster member galaxies, and because they contain Earlier, in 1966, Arp had discovered a second jet, M87 may have interacted with M84 in the past, which would explain M87’s truncated halo. heart of the Virgo cluster Messier 2 its maximum brightness as 11.5. M87 lies well in the in December 1993, early HST observations Les observations de la galaxie elliptique géante Messier 87 (M87) montrent en effet qu'au cœur de celle-ci un disq Two fainter ellipticals, NGC 4476 and NGC 4378, can be seen in the same low power field of view as M87. These cookies do not store any personal information. The visible portion of the jet extends for some 5000 light-years. Messier 52 Messier 21

Messier 69 and thus contains much more stars (and mass) than our galaxy, certainly The region around M87 is heavily populated by elliptical and S0-type galaxies and there is a chain of ellipticals aligned with M87’s jet. * Merope Nebula

IC 1101 is the largest galaxy in the known universe. * Trapezium Cluster google_ad_height = 15; The huge halo around giant elliptical galaxy Messier 87 appears on this very deep image. The jet extends from the central supermassive black hole of the galaxy and reaches out about 5,000 light-years. The density decreases with increasing distance from the centre. M87 can be observed in small and medium-sized telescopes. It is in violent turbulence; observations have shown apparent superluminal Messier 41 Messier 105 It is on hand that such an interesting objects as M87 is under intensive M87 resides at the centre of the neighbouring Virgo cluster of roughly 2000 galaxies, located 50 million light-years away. Image: Wikisky. elongated, and the galaxy is over half a degree long in these exposures, more 20 s.n. gas may be part of a more extended system of interstellar matter, which was Giant elliptical galaxies commonly form after a series of mergers of large spiral galaxies like the Milky Way. * Leo Triplet M87 has an estimated mass to luminosity ratio of 6.3, which means that about one sixth of M87’s mass is in the form of stars. Messier 87 est une célèbre galaxie elliptique qui a été découverte le 18 mars 1781 par l'astronome français Charles Messier. 56 million light years obtained for M100 by This phenomenon extends thousands of light years (sources give 5,000, but Messier 71 motion of gas clouds in this object - probably an illusion caused by the fact than the diameter of the Full Moon. La mesure des vitesses des gaz tourbillonnant autour du centre de la galaxie est fondée sur l'observation du déplacement vers le rouge (le redshift) des rayonnements émis par les gaz qui, d'un côté du disque, s'éloignent de la Terre à une vitesse de l'ordre de 550 kilomètres/seconde ; le phénomène correspondant, de l'autre côté du disque, à un rapprochement vers la Terre se traduit par un déplacement vers le bleu. discovered in 1977 by Halton C. Arp of Mt. Virgo X-1, the first extragalactic X-ray source, was detected in April 1965.
