The Laniakea Supercluster (/ ˌ l ɑː n i. ə ˈ k eɪ. ə /; Hawaiian for "open skies" or "immense heaven") is the galaxy supercluster that is home to the Milky Way and approximately 100,000 other nearby galaxies.
The Milky Way 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.
Although parsecs are used for the shorter distances within the Milky Way, multiples of parsecs are required for the larger scales in the universe, including kiloparsecs (kpc) for the more distant objects within and around the Milky Way, megaparsecs (Mpc) for mid-distance galaxies, and gigaparsecs (Gpc) for many quasars and the most distant ...
The largest supermassive black hole in the Milky Way's vicinity appears to be that of Messier 87 (i.e., M87*), at a mass of (6.5 ± 0.7) × 10 9 (c. 6.5 billion) M ☉ at a distance of 48.92 million light-years.
Located in the Large Magellanic Cloud . Possibly the largest known star. [9] [10] [14] [11] Theoretical limit of star size (Milky Way) ~ 1,500 [15] or ~1,800 [16] Lower value comes from the rough average radii of the three largest stars studied in the paper.
The Laniakea Supercluster is the supercluster that contains the Virgo Cluster, Local Group, and by extension on the latter, our galaxy; the Milky Way. Virgo Supercluster: z= 0.000; Length = 33 Mpc (110 million light-years) It contains the Local Group with our galaxy, the Milky Way.
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. [217]
Contains the Milky Way, and is the first galaxy filament to be discovered. (The first LQG was found earlier in 1982.) A new report in 2014 confirms the Milky Way as a member of the Laniakea Supercluster. CfA2 Great Wall (1989) 750,000,000: Also known as the Coma Wall. Saraswati Supercluster: 652,000,000
A NASA conception of the collision using computer-generated imagery. The Andromeda–Milky Way collision is a galactic collision predicted to occur in about 4.5 billion years between the two largest galaxies in the Local Group —the Milky Way (which contains the Solar System and Earth) and the Andromeda Galaxy.
Typical globular cluster in the Milky Way (overall range: 3 × 10 3 to 4 × 10 6 M ☉) 2 × 10 35 kg Low end of mass range for giant molecular clouds (1 × 10 5 to 1 × 10 7 M ☉) 7.3 × 10 35 kg Jeans mass of a giant molecular cloud at 100 K and density 30 atoms per cubic centimeter; possible example: Orion molecular cloud complex
