Observed structure of the Milky Way 's spiral arms. The Carina–Sagittarius Arm (also known as the Sagittarius Arm or Sagittarius–Carina Arm, labeled -I [clarification needed]) is generally thought to be a minor spiral arm of the Milky Way galaxy. [1] Each spiral arm is a long, diffuse curving streamer of stars that radiates from the ...
MilkyWay@home is a volunteer computing project in the astrophysics category, running on the Berkeley Open Infrastructure for Network Computing (BOINC) platform. Using spare computing power from over 38,000 computers run by over 27,000 active volunteers as of November 2011, the MilkyWay@home project aims to generate accurate three-dimensional dynamic models of stellar streams in the immediate ...
Orion Arm. The Orion Arm, also known as the Orion–Cygnus Arm, is a minor spiral arm within the Milky Way Galaxy spanning 3,500 light-years (1,100 parsecs) in width and extending roughly 10,000 light-years (3,100 parsecs) in length. [2] This galactic structure encompasses the Solar System, including Earth.
The heavenly river ( Milky Way) separates them. The Cowherd and the Weaver Girl are characters found in Chinese mythology and appear eponymously in a romantic Chinese folk tale. The story tells of the romance between Zhinü ( 織女; the weaver girl, symbolized by the star Vega) and Niulang ( 牛郎; the cowherd, symbolized by the star Altair ...
The Milky Way is a barred spiral galaxy with a D 25 isophotal diameter estimated at 26.8 ± 1.1 kiloparsecs (87,400 ± 3,600 light-years), but only about 1,000 light-years thick at the spiral arms (more at the bulge).

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 ...
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.
