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 20,000 light-years (6,100 parsecs) in length. [2] This galactic structure encompasses the Solar System, including Earth.
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.
The Milky Way is a barred spiral galaxy with two major arms and a number of minor arms or spurs. [1] The Perseus Spiral Arm, with a radius of approximately 10.7 kiloparsecs, is located between the minor Cygnus and Carina–Sagittarius Arms. [1] It is named after the Perseus constellation in the direction of which it is seen from Earth.
center – the study of the central region of the Milky Way; disk – the study of the Milky Way disk (the plane upon which most galactic objects are aligned) evolution – the evolution of the Milky Way; formation – the formation of the Milky Way; fundamental parameters – the fundamental parameters of the Milky Way (mass, size etc.)
The Local Group is the galaxy group that includes the Milky Way, where Earth is located. It has a total diameter of roughly 3 megaparsecs (10 million light-years ; 9 × 10 19 kilometres ), [ 1 ] and a total mass of the order of 2 × 10 12 solar masses (4 × 10 42 kg). [ 2 ]
Astronomers used the James Webb Space Telescope to spot a Milky Way-like galaxy that formed soon after the big bang created the universe.
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 Galactic ...
Astronomers on Wednesday announced that they have detected a strong and organized magnetic field twisted in a spiral pattern around the Milky Way's supermassive black hole, revealing previously ...
