What term describes the alignment of three celestial bodies? Comprised of over 2,000 galaxies and located about 54 million light-years away, the Virgo cluster is the nearest large galaxy cluster to Earth. Messier added them to his catalogue, describing them as nebulae without stars. The group itself is a part of the larger Virgo Supercluster, which may be a part of the … While some of the most prominent members can be seen in smaller instruments, a 6-inch telescope will reveal about 160 galaxies in this region on a clear night.Virgo Cluster. This is a compilation of actual images of the groups of galaxies that are in our Local Supercluster.
Our local supercluster, Laniakea, contains the Milky Way, our local group, the Virgo cluster, and... [+] many smaller groups and clusters on the outskirts. 1,100 km/sec, this galaxy must move with over 1,600 km/sec through the

At least 100 galaxy groups and clusters are located within its diameter of 33 megaparsecs (110 million light-years). Based on observations made with the NASA/ESA Hubble Space Telescope, and obtained from the Hubble Legacy Archive, which is a collaboration between the Space Telescope Science Institute (STScI/NASA), the Space Telescope European Coordinating Facility (ST-ECF/ESA) and the Canadian Astronomy Data Centre (CADC/NRC/CSA).The centre of the Virgo Cluster is located between the bright stars Vindemiatrix in Vindemiatrix, Epsilon Virginis, is located near the centre of the The Virgo Cluster galaxies can be seen in the region between Vindemiatrix and Virgo Cluster between Vindemiatrix and Denebola. In addition to the Hubble expansion (see above, and also the If we traveled at 17.3 km/s, it would take 191,000,000,000 years to arrive at the M81 group! Our local supercluster, Laniakea, contains the Milky Way, our local group, the Virgo cluster, and many smaller groups and clusters on the outskirts. Globular clusters, dense bunches of hundreds of thousands of stars, have some of the oldest surviving stars in the universe. As a result, the Local Group of galaxies will likely eventually fall into the Virgo Cluster.With a diameter of approximately 15 million light years, the Virgo Cluster is only slightly larger than the Local Group, but contains 50 times the number of members. 1500 km/sec, with respect to the cluster's center of mass. An excess of light in the top-right part of this halo, and the motion of planetary nebulae in the galaxy, are the last remaining signs of a medium-sized galaxy that recently collided with Messier 87.
The Virgo Cluster is the closest and best-studied great cluster of galaxies, lying at a distance of approximately 20 Mpc in the constellation of Virgo. With over a thousand known members, the cluster spans an area of the sky about 5 by 3 degrees in size. The dynamics of the Local Group are changing, and some astronomers speculated that one day the two large spirals in it (M31 and the Milky Way) may collide and merge to form a giant elliptical galaxy.
