(The disputed Canis Major Dwarf Galaxy, discovered in 2003, might be the actual nearest neighbor.) Though this galaxy is quite big (about 10,000 light years across), it will likely be disrupted by the tidal forces from the Milky Way Galaxy. Discovered in November 2003 by Martin, Ibata, Bellazzini, Irwin, Lewis, The authors find that this concentration is the nucleus of a dwarf galaxy which is in a progressive state of disruption, as it orbits our It is located about 25,000 light-years away. They were made from UK Schmidt plates by David Malin. It is not located in the Solar System. They were certainly known of since the earliest times by the ancient southern astronomers, but these people produced little documentation. the Canis Major Overdensity. Some Milky Way globular clusters are loosely grouped around the nucleus of the This disputed dwarf irregular galaxy is situated at around 25,000 light-years away from us. Bellazzini, Michael J. Irwin, Geraint F. Lewis and Walter Dehnen, Michele Bellazzini, Rodrigo A. Ibata, L. Monaco, Canis Minor is a small constellation in the northern sky. For some … The Large and Small Magellanic clouds were thought to be the closest galaxies to ours, until 1994, when the Sagittarius Dwarf Elliptical Galaxy (SagDEG) was discovered. Officially discovered in 1994, by Rodrigo Ibata, Mike Irwin, and Gerry Gilmore, Sgr dSph was immediately recognized as being the nearest known neighbor to the Milky Way at the time. Canis Major Dwarf Galaxy. (of spectral type M) in the 2MASS All Sky catalog. The supposed small galaxy contains a relatively high percentage of red giant stars, and is thought to contain an estimated one billion stars in all. The new answer to this old question is the Canis Major dwarf galaxy. The Canis Major Dwarf Galaxy (CMa Dwarf) or Canis Major Overdensity (CMa Overdensity) is a disputed dwarf irregular galaxy in the Local Group, located in the same part of the sky as the constellation Canis Major.. If you measure the distance to one object in the LMC, for example, you know the distances to all the millions of objects in the LMC fairly accurately. intergalactic neighbor, and a new dwarf member of the It too, is well-hidden by the dust in the plane of the Milky Way - which is why it wasn't discovered until recently. A dwarf galaxy remnant in Canis Major: the fossil of an in-plane accretion onto the Milky Way. This galaxy is thus our nearest known They have set up research stations along with production facilities and ship yards. It is 25,000 light years away from Earth. In 2003, the Canis Major Dwarf Galaxy was discovered - this is now the closest known galaxy to ours! years. analysis of data on asymmetries in the population of Galactic red giant stars The galaxy contains a relatively high percentage of red giant stars, and is thought to contain an estimated one billion stars in all.. Astronomers primarily use Cepheid and/or RR Lyrae Variables to measure distances to the LMC, the SMC, and the Dwarf Galaxies. l=240deg, b=-8deg in Galactic coordinates, or about RA=07:20, Dec=-30, with an It was only discovered during … Open clusters AM-2 and Tombaugh 2 are strong candidates for being physically Canis Major Dwarf Galaxy, member of the Local Group of galaxies (the group that includes the Milky Way Galaxy) named after the constellation Canis Major, in which it appears to lie.It was discovered in 2003 by a team of astronomers from France, Italy, Australia, and the United Kingdom who were involved in the Two-Micron All Sky Survey (2MASS), a project initiated in the late … This stellar formation is about 42,000 light years from the galactic center , and a mere 25,000 light years from our Solar System. and 42,000 light-years from the center of our It was Magellan, on his trip around the world in 1519, who brought them to our knowledge. (For comparison, our galaxy is 100,000 light years across.) Of course, there are not all exactly the same, but the thickness of LMC, as seen from the Earth, is much smaller than the typical uncertainties in the distances to individual objects in the Milky Way. Maffei 2 has a spiral structure and is … The SagDEG is on the other side of the Milky Way from the Sun, about 70,000 light years away. The Canis Major Dwarf is an irregular dwarf galaxy that is a satellite of our own Milky Way Galaxy.It lies in the constellation Canis Major at a distance of only 25,000 light-years from the Sun and 42,000 light-years from the center of the Milky Way. The Canis Major dwarf is a mere 42,000 light-years from the Milky Way's core and only 25,000 light-years from Earth. ESO 489-056 - Dwarf Galaxy - Hubble Space Telescope - August, 2013 The SMC, also an irregular galaxy, may be a distorted barred disk, deformed by the tidal forces of Milky Way and LMC. Milky Way Galaxy. The SMC is further out, at 210,000 light years. elliptical-shaped over-density close to the Galactic plane, around the position The Canis Major Dwarf Galaxy is a galaxy in the Local Group, located in the same part of the sky as the constellation Canis Major.. For example, astronomers have studied the supernova remnants to compare with theoretical models, or to derive a relationship between their size, energy, and brightness. M79, They only managed to reach the galaxy with the use of experimental wormhole drives which allow fleets of ships to move from the Milky Way to the Canis Major galaxy. The Large Magellanic Cloud, 1,690,000,000,000,000,000 km (179,000 light years) away, was once considered the nearest galaxy outside of the Milky Way.
