At the time of its announcement, the Canis Major Dwarf Galaxy is classified as an irregular galaxy and is thought to be the closest neighboring galaxy to the Earth's location in the Milky Way, being located about 25,000 light-years (7.7 kiloparsecs) away from the Solar System [2] and 42,000 ly (13 kpc) from the Galactic Center.
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, [3] the MilkyWay@home project aims to generate accurate three-dimensional dynamic models of stellar streams in the ...
In 1932, American physicist and radio engineer Karl Jansky detected radio waves coming from an unknown source in the center of the Milky Way galaxy. Jansky was studying the origins of radio frequency interference for Bell Laboratories. He found "...a steady hiss type static of unknown origin", which eventually he concluded had an ...
In the Lambda-CDM model of the universe, galaxies grow by mergers.Such mergers are the cause of substructure observed in the stellar halo of galaxies; streams of stars from disrupted satellite galaxies are detectable through their coherence in space or velocity; a number of these streams are observable around the Milky Way.

The Scutum–Centaurus Arm, also known as Scutum-Crux arm, is a long, diffuse curving streamer of stars, gas and dust that spirals outward from the proximate end of the Milky Way's central bar. The Milky Way has been posited since the 1950s to have four spiral arms; numerous studies contest or nuance this number. [1]
Tianhe-2 or TH-2 (Chinese: 天河-2; pinyin: tiānhé-èr; lit. 'Heavenriver-2', i.e. 'Milky Way 2') is a 3.86-petaflop supercomputer located in the National Supercomputer Center in Guangzhou, China. [3]
The Galactic Center GeV Excess (GCE) is an unexpected surplus of gamma-ray radiation in the center of the Milky Way galaxy. This spherical source of radiation was first detected in 2009 [ 1 ] [ 2 ] by the Fermi Gamma-ray Space Telescope and is unexplained by direct observation. [ 3 ]
