A gas giant is a giant planet composed mainly of hydrogen and helium. [2] Jupiter and Saturn are the gas giants of the Solar System. The term "gas giant" was originally synonymous with "giant planet". However, in the 1990s, it became known that Uranus and Neptune are really a distinct class of giant planets, being composed mainly of heavier ...
Globular clusters are found in nearly all galaxies. In spiral galaxies like the Milky Way, they are mostly found in the outer spheroidal part of the galaxy – the galactic halo. They are the largest and most massive type of star cluster, tending to be older, denser, and composed of lower abundances of heavy elements than open clusters, which are generally found in the disks of spiral galaxies ...
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.
A new, incredibly detailed 3D map of the Milky Way has revealed that its central disk is wavy, much like an enormous potato chip.This new picture of the galactic disk — the central region of the ...
Sagittarius A*, abbreviated Sgr A* ( / ˈsædʒ ˈeɪ stɑːr / SADGE-AY-star [3] ), is the supermassive black hole [4] [5] [6] 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, [7] visually close to the Butterfly Cluster (M6) and Lambda Scorpii .
Satellite galaxies that orbit from 1,000 ly (310 pc) of the edge of the disc of the Milky Way Galaxy to the edge of the dark matter halo of the Milky Way at 980,000 ly (300 kpc) from the center of the galaxy, [a] are generally depleted in hydrogen gas compared to those that orbit more distantly. This is because of their interactions with the dense hot gas halo of the Milky Way that strip cold ...
Eventually, in roughly 6 billion years, the Milky Way and Andromeda will complete their merger into a giant elliptical galaxy. During the merger, if there is enough gas, the increased gravity will force the gas to the centre of the forming elliptical galaxy.
The Galactic Center is the barycenter of the Milky Way and a corresponding point on the rotational axis of the galaxy. [1] [2] Its central massive object is a supermassive black hole of about 4 million solar masses, which is called Sagittarius A*, [3] [4] [5] a compact radio source which is almost exactly at the galactic rotational center. [clarification needed] The Galactic Center is ...
The Laniakea Supercluster ( / ˌlɑːni.əˈkeɪ.ə /; Hawaiian for "open skies" or "immense heaven") [2] is the galaxy supercluster that is home to the Milky Way and approximately 100,000 other nearby galaxies.
Sagittarius B2 ( Sgr B2) is a giant molecular cloud of gas and dust that is located about 120 parsecs (390 ly) from the center of the Milky Way. This complex is the largest molecular cloud in the vicinity of the core and one of the largest in the galaxy, spanning a region about 45 parsecs (150 ly) across. [2]
