Milky Way is a brand of chocolate-covered confectionery bar manufactured and marketed by Mars Inc..There are two varieties: the U.S. Milky Way bar, which is sold as the Mars bar worldwide, including Canada; and the global Milky Way bar, which is sold as the 3 Musketeers in the U.S. and Canada (neither bar is sold as Milky Way in Canada).
The Scutum–Centaurus Arm, also known as Scutum-Crux arm, is a long, diffuse curving streamer of stars, gas and dust that spirals outward from the proximate end of the Milky Way's central bar. The Milky Way has been posited since the 1950s to have four spiral arms; numerous studies contest or nuance this number. [1]
The Gould Belt is a local ring of stars in the Milky Way, tilted away from the galactic plane by about 16–20 degrees, first reported by John Herschel and Benjamin Gould in the 19th century. [1] It contains many O- and B-type stars, and many of the nearest star-forming regions of the local Orion Arm, to which the Sun belongs.
Astronomers using the Gaia space telescope have located two ancient streams of stars that helped the Milky Way galaxy grow and evolve more than 12 billion years ago.
Figure 1.The observed structure of the Milky Way's spiral arms [1]. 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]

Note: in addition to this statement, there must be a statement on this page explaining why the work is in the public domain in the U.S. (for the first case) or why it was PD on the URAA date in its source country (second case).
The discovery of the star in the Milky Way Galaxy suggests that the galaxy may be at least 3 billion years older than previously thought. [265] [266] [267] Several individual stars have been found in the Milky Way's halo with measured ages very close to the 13.80-billion-year age of the Universe.
The Milky Way Galaxy.. The Monoceros Ring (from Greek monoceros 'unicorn') is a long, complex ring of stars that wraps around the Milky Way three times. This is proposed to consist of a stellar stream torn from the Canis Major Dwarf Galaxy by tidal forces as part of the process of merging with the Milky Way over a period of billions of years, although this view has long been disputed.
