The name Sirius comes from the Greek Σείριος (Seirios), which means “scorching,” “glowing” or “searing.” In ancient times, the star rose just before sunrise during the hottest summer period, the so-called Dog Days. Nevertheless, our results suggest that the 2MASS M giant overdensity previously claimed to represent the core of a dwarf galaxy in Canis Major (l ~ 240 deg) is an artifact of a dust extinction window opening to the overall density rise to the more significant Argo structure centered at larger longitude (l ~ 290 +- 10 deg, b ~ -4 +- 2 deg). Identify the disk, bulge, halo, and spiral arms, and indicate the galaxy's approximate dimensions . The cluster is approximately 2,300 light years distant. No other star has ever been as bright since, nor is one expected to be in the next five million years. It is approximately 500 light years distant. The Canis Major Dwarf Galaxy is estimated to contain 1 billion stars, many of which are red giants. Its name comes from the Arabic aðāra, which means “virgins.” It is a binary star that lies about 430 light years from Earth. This galaxy is situated at around 42,000 light-years away from the Galactic Center. The constellation is depicted as a dog standing on its hind legs, pursuing a hare, represented by the constellation Lepus. The star’s name comes from the Arabic word for “the herald,” presumably referring to Mirzam’s position in the sky. Canis Major represents the bigger dog following Orion, the hunter in Greek mythology. Greeks and Romans believed the star was somehow responsible for the summer heat. For many years astronomers thought the Large Magellan Cloud (LMC) was closest, but its title was supplanted in 1994 by the Sagittarius dwarf galaxy. All rights reserved. Explanation: What is the closest galaxy to the Milky Way? Its name is derived from the Arabic al-wazn“, meaning “the weight.” The star’s estimated age is 10 million years, which means that it will become a red supergiant within the next 100,000 years, and eventually a supernova. en Our home galaxy, the Milky Way, is thought to be currently absorbing smaller galaxies in this fashion, such as the Canis Major Dwarf Galaxy, and possibly the Magellanic Clouds.

The gift proved to be an unfortunate one, as Europa herself was killed accidentally by her husband Cephalus, who was out hunting with the javelin. A dwarf galaxy is a small galaxy composed of about 1000 up to several billion stars, as compared to the Milky Way's 200–400 billion stars. Sirius A belongs to the spectral class A1V, and the dwarf to DA2. It has an apparent magnitude of 1.83. Tau Canis Majoris Cluster (NGC 2362), photo: NASA, JPL-Caltech, Harvard-Smithsonian CfA. Like Laelaps, the fox was extremely fast and was destined never to be caught. 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.. Canis Major is a constellation in the southern celestial hemisphere.In the second century, it was included in Ptolemy's 48 constellations, and is counted among the 88 modern constellations.Its name is Latin for "greater dog" in contrast to Canis Minor, the "lesser dog"; both figures are commonly represented as following the constellation of Orion the hunter through the sky. WikiMatrix. Other globular clusters that orbit the center of our Milky Way as a satellite – i.e. Its brightness varies between magnitude 4.32 and 4.37 with a period of 1.28 days. These clusters are thought to be remnants of the dwarf’s globular cluster system before the galaxy started getting pulled apart and swallowed into the Milky Way. July 12, 2014 by admin The Large Magellanic Cloud (LMC) is a dwarf irregular galaxy located on the border between the constellations Dorado and Mensa. Colliding spiral galaxies NGC 2207 and IC 2163, photo: ESO. It is a difficult object to observe because it lies behind the plane of the Milky Way, obscured by stars, dust and gas. Messier 41 (NGC 2287), Atlas Image mosaic courtesy of 2MASS/UMass/IPAC-Caltech/NASA/NSF. There are hundreds of billions of stars in our galaxy, the Milky Way. So, in conclusion, the best answer we have to the question ‘how many planets are there?’ is: 8 planets in the solar system (maybe 9) 400 billion planets in … Canis Major Map, by IAU and Sky&Telescope magazine. The galaxy is believed to be a satellite of the Milky Way and a member of the Local Group of galaxies, which includes about 30 galaxies that are loosely bound together by their gravitation. The star’s heliacal rising, just before the annual flooding and the summer solstice, played a crucial role in the Egyptian calendar during the Middle Kingdom era. The brightest star in Canis Major, Sirius (Alpha Canis Majoris), is also the brightest star in the night sky.

The cluster contains about 100 stars, with the brightest one being a K3-type giant located near the centre of the cluster. It is part of the Phantom Zone Subsector. The galaxies were discovered by the English astronomer John Herschel in 1835. In Chinese astronomy, the constellation of Canis Major is located in the Vermilion Bird. The galaxies are in the process of tidal stripping, with the larger galaxy pulling stars and other material from the smaller one. They have set up research stations along with production facilities and ship yards. All other trademarks and copyrights are the property of their respective owners. This paper summarizes the recent discovery of another potential Milky Way accretion event, the Canis Major dwarf galaxy.
