The Milky Way [c] is the galaxy that includes the Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye.
As of 21 May 2015, WISE-J224607.57-052635.0-20150521 is the most luminous galaxy discovered and releases 10,000 times more energy than the Milky Way galaxy, although smaller. Nearly 100 percent of the light escaping from this dusty galaxy is Infrared radiation.

It consists of two collections of galaxies in a "dumbbell" shape; the Milky Way and its satellites form one lobe, and the Andromeda Galaxy and its satellites constitute the other. The two collections are separated by about 800 kiloparsecs (3 × 10 ^ 6 ly; 2 × 10 19 km) and are moving toward one another with a velocity of 123 km/s . [ 3 ]
The Milky Way has several smaller galaxies gravitationally bound to it, as part of the Milky Way subgroup, which is part of the local galaxy cluster, the Local Group. [ 1 ] There are 61 small galaxies confirmed to be within 420 kiloparsecs (1.4 million light-years ) of the Milky Way, [ 2 ] but not all of them are necessarily in orbit, and some ...
The Milky Way started out small and grew in size as it merged with other galaxies, gaining stars as well as hydrogen to form more stars. Each galaxy has hydrogen gas that aids in the birth of stars.
The Milky Way galaxy is a member of an association named the Local Group, a relatively small group of galaxies that has a diameter of approximately one megaparsec. The Milky Way and the Andromeda Galaxy are the two brightest galaxies within the group; many of the other member galaxies are dwarf companions of these two. [176]
Astronomers have identified two ancient streams of stars - named after the Hindu deities Shakti and Shiva - that appear to be among the Milky Way's earliest building blocks, offering new insight ...
