Laniakea Supercluster is the galaxy supercluster that includes the Milky Way and about 100,000 other nearby galaxies. It was defined in 2014 by a new method based on galaxy velocities and has four subparts: Virgo, Hydra–Centaurus, Great Attractor, and Antlia Wall.
The Milky Way is the galaxy that includes the Solar System, with a diameter of 26.8 ± 1.1 kiloparsecs (87,400 ± 3,600 light-years ). It is a barred spiral galaxy with a supermassive black hole at its center and many satellite galaxies.
Astronomers have made the most detailed infrared map of our galaxy ever made. The huge map has already helped changed our view of the galaxy in unexpected ways, according to its creators. In all ...
A clickable map of the nearby circa one-sixth outer sector of the galaxy, thus clearly showing the Local Arm (Orion Arm) and neighboring arms - as well as the Great Orion Nebula (as a very luminous feature of the less bright Orion molecular cloud complex) and broad-clouds North America Nebula (and Pelican Nebula) which is an intrinsic part of the Radcliffe wave.
The Galactic Center is the barycenter of the Milky Way and a corresponding point on the rotational axis of the galaxy. It contains a supermassive black hole of about 4 million solar masses, called Sagittarius A*, which is a compact radio source near the galactic rotational center.
Previously, astronomers have spotted the supermassive black hole at the center of the Milky Way giving a swift kick to a star, which will leave the galaxy for good in about 100 million years. A ...
The Great Attractor is a massive concentration of galaxies that pulls on the Milky Way and other nearby galaxies. It is located in the direction of the constellations Triangulum Australe and Norma, and is part of the Laniakea Supercluster.
A major astronomical project that imaged and spectroscopically studied over 35% of the sky and 4 million objects. The survey data, released in several phases, provide insights into the structure, evolution and history of the universe.
