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.
Local Sheet. The Local Sheet in astronomy is a nearby extragalactic region of space where the Milky Way, the members of the Local Group and other galaxies share a similar peculiar velocity. [2] This region lies within a radius of about 7 Mpc (23 Mly ), [3] 0.46 Mpc (1.5 Mly) thick, [1] and galaxies beyond that distance show markedly different ...
List of stellar streams. This is a list of stellar streams. A stellar stream is an association of stars orbiting a galaxy. It was once a globular cluster or dwarf galaxy that has now been torn apart and stretched out along its orbit by tidal forces. [1] An exception in the list about Milky Way streams given below is the Magellanic Stream ...
Melkweg. Melkweg (Dutch for "Milky Way") is a music venue and cultural center on Lijnbaansgracht, near Leidseplein in Amsterdam, Netherlands. It is housed in a former dairy and includes four music halls as well as a cinema, a restaurant and an exhibition space. It is operated by a nonprofit organisation founded in 1970.

Sagittarius A*, abbreviated Sgr A* (/ ˈ s æ dʒ ˈ eɪ s t ɑːr / SADGE-AY-star), is the supermassive black hole at the Galactic Center of the Milky Way.Viewed from Earth, it is located near the border of the constellations Sagittarius and Scorpius, about 5.6° south of the ecliptic, visually close to the Butterfly Cluster (M6) and Lambda Scorpii.
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.. There are 61 small galaxies confirmed to be within 420 kiloparsecs (1.4 million light-years) of the Milky Way, but not all of them are necessarily in orbit, and some may themselves be in orbit of other satellite galaxies.
High-velocity clouds ( HVCs) are large collections of gas found throughout the galactic halo of the Milky Way. Their bulk motions in the local standard of rest have velocities which are measured in excess of 70–90 km s −1. These clouds of gas can be massive in size, some on the order of millions of times the mass of the Sun ( ), and cover ...
