A galaxy is a system of stars, stellar remnants, interstellar gas, dust, and dark matter bound together by gravity. [1] [2] The word is derived from the Greek galaxias (γαλαξίας), literally 'milky', a reference to the Milky Way galaxy that contains the Solar System.
Size (left) and distance (right) of a few well-known galaxies put to scale. There are an estimated 100 billion galaxies in all of the observable universe. [1] On the order of 100,000 galaxies make up the Local Supercluster, and about 51 galaxies are in the Local Group (see list of nearest galaxies for a complete list).
Galaxie is a Francophone indie garage rock band formed in 2002 in Montreal, Quebec, Canada. Formerly known as Galaxie 500 , they should not be confused with the American alternative rock band Galaxie 500 .
This aspect can be noticeable in the region between the bulge and the disk.The bulge is a tightly packed groups of stars within a larger formation, and a disk is a component of disk galaxies consisting of gas and stars.
Messier 63 or M63, also known as NGC 5055 or the seldom-used Sunflower Galaxy, [6] is a spiral galaxy in the northern constellation of Canes Venatici with approximately 400 billion stars. [7] M63 was first discovered by the French astronomer Pierre Méchain , then later verified by his colleague Charles Messier on 14 June 1779. [ 6 ]
HD1 is one of the earliest and most distant known galaxies yet identified in the observable universe, having a spectroscopic redshift of z = 13.27, meaning that the light from the galaxy travelled for 13.5 billion years on its way to Earth, which due to the expansion of the universe, corresponds to a proper distance of approximately 33.4 billion light-years (10.2 billion parsecs).
Galaxy morphological classification is a system used by astronomers to divide galaxies into groups based on their visual appearance. There are several schemes in use by which galaxies can be classified according to their morphologies, the most famous being the Hubble sequence , devised by Edwin Hubble and later expanded by Gérard de ...
Original logo of Galaxie from 1997 to 2000. From 2000 to 2003, the orange circle was removed. The service's beginnings in Canada started in December 1995, when the Canadian Broadcasting Corporation was granted approval from the Canadian Radio-television and Telecommunications Commission (CRTC) to launch a national pay audio service named Galaxie consisting of 30 channels in both English and ...
