The Milky Way, or "milk circle", was just one of 11 "circles" the Greeks identified in the sky, others being the zodiac, the meridian, the horizon, the equator, the tropics of Cancer and Capricorn, the Arctic Circle and the Antarctic Circle, and two colure circles passing through both poles.
The Milky Way Project is a Zooniverse project whose main goal is to identify stellar-wind bubbles in the Milky Way Galaxy. Users classify sets of infrared images from the Spitzer Space Telescope and the Wide-field Infrared Survey Explorer (WISE). [1] Scientists believe bubbles in these images are the result of young, massive stars whose light ...
The nature of the Milky Way's bar, which extends across the Galactic Center, is also actively debated, with estimates for its half-length and orientation spanning between 1–5 kpc (short or a long bar) and 10–50°. [23] [25] [27] Certain authors advocate that the Milky Way features two distinct bars, one nestled within the other. [28]
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 ...
Story at a glance (NewsNation) — This summer, you can gaze at the Milky Way without the need for a telescope, but you may have to drive a bit to get a good view. The center of our galaxy is ...
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 ...
Harlow Shapley. Harlow Shapley (November 2, 1885 – October 20, 1972) was an American scientist, head of the Harvard College Observatory (1921–1952), and political activist during the latter New Deal and Fair Deal. [1][2] Shapley used Cepheid variable stars to estimate the size of the Milky Way Galaxy and the Sun's position within it. [3]
The image clearly presents the Milky Way as a barred spiral galaxy with fairly symmetric four major arms and some extra arm segments and spurs. [3] [4] The Perseus Arm is one of the four major arms. The arm is the length of more than 60,000 lr and the width of about 1,000 lr and the spiral extension in the pitch angle near 9 degree. [3]
