Dwarf galaxy found orbiting our home galaxy, Milky Way: 7 galaxies you haven’t heard of

first_imgA dwarf galaxy has been found orbiting Milky Way and as per the astronomers, the neighbour galaxy could be the faintest dwarf satellite discovered so far. It has been located near constellation Virgo which is about 280,000 light years from the sun.What is a galaxy? The word galaxy is derived from the Greek term ‘galaxias’ which means ‘milky’, a reference to the Milky Way. It is a gravitationally bound system of stars, gas, dust and dark matter. It varies in size, from tiny particles with just a few thousand stars, to giants with one hundred trillion stars.What is Milky Way?It is the spiral galaxy that contains our solar system. The term is derived from a Latin word ‘lactea’ means ‘milky circle’. It looks like a faint luminous band stretching across the heavens, composed of approximately a trillion stars, most of which are too distant to be seen individually.Here is the list of some other known galaxies:AndromedaIt is a spiral galaxy also known as Messier 31 (M31) or NGC 24, approximately 780 kiloparsecs (2.5 million light-years) from Earth and it is nearest to the Milky Way. It’s size is of around 1.5*1012 solar masses and according to a study in 2009, both the Milky Way and M31 are equal in mass.Black Eye GalaxyPopularly known as Messier 64 (M64), this galaxy was discovered by Edward Pigott  and Johann Elert Bode in 1779 as well as by Charles Messier in 1780. M64 is also called as ‘Black Eye’ or ‘Evil Eye’ galaxy and is well known among amateur astronomers.advertisementMessier 81Popularly known as Bode’s Galaxy, it was first discovered by Johann Elert Bode in 1774. It is the largest galaxy in the M81 group located in the constellation Ursa Major.Cartwheel GalaxyPopularly known as a lenticular galaxy, it was discovered by Fritz Zwicky in 1941. It lies about 500 million light years away in the constellation Sculptor and has a size of about (2.9-4.8)*109 solar masses and rotates at a speed of around 217k m/s.Cigar GalaxyPopularly known as Messier 82, it was discovered by the scientist on January 21,2014. It lies about 12 million light years away in the constellation Ursa Major and is five times more brighter than the whole Milky Way.Comet GalaxyIt was discovered on March 2, 2007 with the help of the Hubble Space Telescope. It is a spiral galaxy situated 3.2 light-years away from Earth, in the galaxy cluster Abell 2667.Whirlpool GalaxyAlso known as Messier 51a, M51a, or NGC 5194, Whirlpool galaxy is located at a distance of 13 million light-years in the Canes Venatici constellation. One of the most spiral galaxies, Whirlpool galaxy is also one of the nebulae which sports a spiral structure. Since it is pretty interactive, professional astronomers use it to study and understand galaxy structure. Image Source: NASA Interested in General Knowledge and Current Affairs?
