Sagittarius A ( Sgr A) is a complex radio source at the center of the Milky Way, which contains a supermassive black hole. It is located between Scorpius and Sagittarius, and is hidden from view at optical wavelengths by large clouds of cosmic dust in the spiral arms of the Milky Way.
The Milky Way is the "steam" coming from the spout. The galactic center Sagittarius A* is located off the top of the spout. As seen from the northern hemisphere, the constellation's brighter stars form an easily recognizable asterism known as "the Teapot ".
Alpha Centauri ( α Centauri, α Cen, or Alpha Cen) is a triple star system in the southern constellation of Centaurus. It consists of three stars: Rigil Kentaurus ( α Centauri A ), Toliman ( α Centauri B ), and Proxima Centauri ( α Centauri C ). [14] Proxima Centauri is the closest star to the Sun at 4.2465 light-years (1.3020 pc ).
Two very large nearby galaxies, Maffei 1 and Maffei 2, were discovered in the Zone of Avoidance by Paolo Maffei by their infrared emission in 1968. Even so, approximately 10% of the sky remains difficult to survey as extragalactic objects can be confused with stars in the Milky Way. Projects to survey the Zone of Avoidance at radio wavelengths ...
UY Scuti ( BD-12°5055) is a red supergiant star, located 5,900 light-years away in the constellation Scutum. It is also a pulsating variable star, with a maximum brightness of magnitude 8.29 and a minimum of magnitude 10.56, which is too dim for naked-eye visibility. It is considered to be one of the largest known stars, with a radius ...
Leo I is a dwarf spheroidal galaxy in the constellation Leo. At about 820,000 light-years distant, it is a member of the Local Group of galaxies and is thought to be one of the most distant satellites of the Milky Way galaxy. It was discovered in 1950 by Albert George Wilson on photographic plates of the National Geographic Society – Palomar ...
NGC 6397 (also known as Caldwell 86) is a globular cluster in the constellation Ara that was discovered by French astronomer Nicolas-Louis de Lacaille in 1752. [9] It is located about 7,800 light-years from Earth, [3] making it one of the two nearest globular clusters to Earth (the other one being Messier 4 ).
The Sombrero Galaxy (also known as Messier Object 104, M104 [4] or NGC 4594) is a peculiar galaxy of unclear classification [6] in the constellation borders of Virgo and Corvus, being about 9.55 megaparsecs (31.1 million light-years) [2] from the Milky Way galaxy. It is a member of the Virgo II Groups, a series of galaxies and galaxy clusters ...
