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.
Sagittarius A*, abbreviated as 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.
A starchart of the night sky towards the Galactic Center. The Galactic Center is the barycenter of the Milky Way and a corresponding point on the rotational axis of the galaxy. [1] [2] Its central massive object is a supermassive black hole of about 4 million solar masses, which is called Sagittarius A*, [3] [4] [5] a compact radio source which ...
The Sagittarius Dwarf Spheroidal Galaxy ( Sgr dSph ), also known as the Sagittarius Dwarf Elliptical Galaxy ( Sgr dE or Sag DEG ), is an elliptical loop-shaped satellite galaxy of the Milky Way. It contains four globular clusters in its main body, [8] with the brightest of them— NGC 6715 (M54)—being known well before the discovery of the ...
Galactic bulge. Artist's impression of the central bulge of the Milky Way [1] In astronomy, a galactic bulge (or simply bulge) is a tightly packed group of stars within a larger star formation. The term almost exclusively refers to the central group of stars found in most spiral galaxies (see galactic spheroid ).
Night on the Galactic Railroad (銀河鉄道の夜, Ginga Tetsudō no Yoru), sometimes translated as Milky Way Railroad, Night Train to the Stars or Fantasy Railroad in the Stars, [1] is a classic Japanese fantasy novel by Kenji Miyazawa written around 1927. The nine-chapter novel was posthumously published by Bunpodō (文圃堂) in 1934 as ...
List of globular clusters. Image taken by ESO 's VISTA of the Globular Cluster VVV CL001. On the right lies the globular star cluster UKS 1 and on the left lies a much less conspicuous new discovery, VVV CL001. [1] The two are not physically located close to each other; this is a line-of-sight coincidence. [2]
The Milky Way has several smaller galaxies gravitationally bound to it, as part of the Milky Way subgroup, which is part of the local galaxy cluster, the Local Group.. There are 61 small galaxies confirmed to be within 420 kiloparsecs (1.4 million light-years) of the Milky Way, but not all of them are necessarily in orbit, and some may themselves be in orbit of other satellite galaxies.
