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).
Packaging used by Galaxy until 2020 The old packaging used by Galaxy During the 1980s, similar to other chocolate brands, Galaxy advertised itself on TV. Galaxy is a chocolate bar, made and marketed by Mars Inc., and first manufactured in the United Kingdom in 1960. [1]
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.
Size (left) and distance (right) of a few well-known galaxies put to scale. There are an estimated 100 billion galaxies in all of the observable universe. [1] On the order of 100,000 galaxies make up the Local Supercluster, and about 51 galaxies are in the Local Group (see list of nearest galaxies for a complete list).
In 2019, astronomers discovered the young star cluster Price-Whelan 1 using Gaia data. The star cluster has a low metallicity and belongs to the leading arm of the Magellanic Clouds. The existence of this star cluster suggests that the leading arm of the Magellanic Clouds is 90,000 light-years away from the Milky Way—closer than previously ...
HD 140283 (also known as the Methuselah star) is a metal-poor subgiant star about 200 light years away from the Earth in the constellation Libra, near the boundary with Ophiuchus in the Milky Way Galaxy. Its apparent magnitude is 7.205, so it can be seen with binoculars. It is one of the oldest stars known.
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]
Listed below are galaxies with diameters greater than 700,000 light-years. This list uses the mean cosmological parameters of the Lambda-CDM model based on results from the 2015 Planck collaboration, where H 0 = 67.74 km/s/Mpc, Ω Λ = 0.6911, and Ω m = 0.3089. [3]
