Farther still at 75 million light-years is NGC 2280, a spiral galaxy with a magnitude of 11.0. The remaining five stars known to host planets in Canis Major are all very dim and far away, and the planets are all large gas giants. NGC 2359 is an emission nebula, given the name Thor's Helmet. There are 1 billion stars in the canis galaxy. a galaxy that has no elliptical or spiral shape, and hence it does not come under the Hubble Sequence of regular galaxy classes. A closeup of the central region of NGC 2359 reveals the giant Wolf Rayet star HD 56925, very bright in the left centre of the image below. By the time the hot days of July and August arrive, Sirius is rising with the Sun, and the "dog days of summer" are upon us. 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. With a magnitude of 14.7, the dwarf galaxy is only visible in large telescopes. 11. Eta Canis Majoris is Aludra, Arabic for the virgin. With a magnitude of -1.46, it is more than twice as bright as the next brightest star, magnitude -0.72 Canopus. The large spiral galaxy, NGC 2207, is in the process of assimilating the smaller spiral galaxy, IC 2163. Copyright © 2020 Bright Hub PM. In ancient times it was thought the energy of Sirius combined with the Sun at this time, and the star was blamed, in the words of Robert Burnham Jr., for "bringing forth fever in men and madness in dogs.". 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 Surface Temperature of Venus--Why is it so Hot? It has recently been settled by the Solarian Kingdom. The Canis Major Galaxy is the nearest dwarf galaxy to the Milky Way.

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. It is an irregular galaxy, i.e. Some Egyptian temples were aligned with window openings facing east, directly where the Dog Star rose, and when the light from the star shone through the opening, it meant the Nile was about to commence its annual flood, spreading its waters and rich soil over the adjoining floodplain, an occurrence critical to the survival of the Egyptian people. The galaxy contains a relatively high percentage of red giant stars, and is thought to contain an estimated one billion stars in all.. With a magnitude of 14.7, the dwarf galaxy is only visible in large telescopes. Scientists world wide were quick to analyze his data and his theories, and most, including legendary astronomer Carl Sagan, found them wanting. Looking outside our galaxy, the first object of interest is ESO 489-056, a dwarf galaxy 16 million light years away containing about one billion stars. Astronomers are of the opinion that the Canis Major dwarf galaxy may have been brought together with different globular clusters, including NGC 2298 and NGC 1851. There is a black hole at the center of the galaxy that is estimated to be … ; Canis Minor would later be included in the 88 modern constellations, where it holds the 71 st place in regards to size, stretching for around 183 square degrees. All Rights Reserved. Canis Major Dwarf Galaxy Facts. In the image of Pisces A, at left, the bright object at the top of the image is a distant background galaxy. a galaxy that has no elliptical or spiral shape, and hence it does not come under the Hubble Sequence of regular galaxy classes. As the name suggests, a dwarf galaxy is a small galaxy made up of a billion stars. The next closest galaxy is the Sagittarius Dwarf Elliptical Galaxy, which was discovered in 1994. You can see the little dwarf as a small white dot in the lower left of the Hubble image below. 1. At magnitude 4.5 it is visible to the naked eye, and a good target for backyard telescopes. It is a grand design spiral galaxy located about 31 million light years from the Milky Way. Canis Major represents Laelaps, the mythical dog who’s prey couldn’t escape him. 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 galaxy is over 190 million years old. Almost twice as far at 106 light years is HD 45364, a G8V yellow main sequence star similar to our Sun. Pisces Dwarf (unclear if it is a satellite of the Andromeda Galaxy or the Triangulum Galaxy) Other Galaxies in the Local Group There some "oddball" galaxies in the Local Group that may not be gravitationally "bound" to either the Andromeda or the Milky Way galaxies. Some suggest that colours were sometimes interpreted differently in ancient times. It is a B1III blue giant, 450 light years away. The galaxy, which is also known as Messier 51a, is interacting with NGC 5195 (Messier 51b), a dwarf galaxy, also in Canes Venatici. Although it is unnamed and well beyond naked visibility, it is one of the largest stars ever discovered. Virgil wrote, "the Dog Star, that burning constellation, when he brings drought and diseases on sickly mortals, rises and saddens the sky with inauspicious light".
