Milky Way Galaxy: This is now categorized a globular cluster of the Milky Way. However, it is considered the core of a dwarf galaxy that the Milky Way cannibalized. Mayall II: Andromeda Galaxy: This is now categorized a globular cluster of Andromeda. However, it is considered the core of a dwarf galaxy that Andromeda cannibalized. Gaia Sausage
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] It consists of two collections of galaxies in a " dumbbell " shape; the ...
A galaxy is a system of stars, stellar remnants, interstellar gas, dust, and dark matter bound together by gravity. [1] [2] The word is derived from the Greek galaxias ( γαλαξίας ), literally 'milky', a reference to the Milky Way galaxy that contains the Solar System.
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 started out small and grew in size as it merged with other galaxies, gaining stars as well as hydrogen to form more stars. Each galaxy has hydrogen gas that aids in the birth of stars.
The Tarantula Nebula has an apparent magnitude of 8. Considering its distance of about 49 kpc [2] (160,000 light-years ), this is an extremely luminous non-stellar object. Its luminosity is so great that if it were as close to Earth as the Orion Nebula, the Tarantula Nebula would cast visible shadows. [13]
Planetary nebula IC 289 is a cloud of ionised gas being pushed out into space by the remnants of the star's core. A rich section of the Milky Way runs through Cassiopeia, stretching from Perseus towards Cygnus, and it contains a number of open clusters, young luminous galactic disc stars, and nebulae.
Milky Way is a brand of chocolate-covered confectionery bar manufactured and marketed by Mars, Incorporated. There are two varieties: the US 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 US and Canada (neither bar is sold as Milky Way in Canada).
Sagittarius A*, abbreviated Sgr A* (/ ˈ s æ dʒ ˈ eɪ s t ɑːr / SADGE-AY-star), is the supermassive black hole 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, visually close to the Butterfly Cluster (M6) and Lambda Scorpii.
Ophiuchus contains several star clusters, such as IC 4665, NGC 6633, M9, M10, M12, M14, M19, M62, and M107, as well as the nebula IC 4603-4604. M9 is a globular cluster which may have an extra-galactic origin. M10 is a fairly close globular cluster, only 20,000 light-years from Earth. It has a magnitude of 6.6 and is a Shapley class VII cluster.
