The Whirlpool Galaxy, also known as Messier 51a (M51a) or NGC 5194, is an interacting grand-design spiral galaxy with a Seyfert 2 active galactic nucleus. [ 6 ] [ 7 ] [ 8 ] It lies in the constellation Canes Venatici , and was the first galaxy to be classified as a spiral galaxy. [ 9 ]
NGC 5195 (also known as Messier 51b or M51b) is a dwarf galaxy that is interacting with the Whirlpool Galaxy (also known as M51a or NGC 5194). Both galaxies are located approximately 25 million light-years away in the constellation Canes Venatici. Together, the two galaxies are one of the most famous interacting galaxy pairs.
The most famous of these objects is the Whirlpool Galaxy (M51; Arp 85), which is composed of a spiral galaxy NGC 5194 that is interacting with a smaller elliptical galaxy NGC 5195. The interaction has distorted the shape of both galaxies; the spiral arm pattern has been enhanced in the larger spiral galaxy, and a bridge of stars and gas has ...
The Whirlpool Galaxy lies about 27 million light-years away and contains hundreds of billions of stars. The stars are spread out into a pinwheel shape clustered around a black hole at its core.
The cloud resides near the galaxy’s center, about 26,000 light-years from Earth, according to NASA. - Adam Ginsburg The trouble was, “there’s so many stars at the galactic center that it ...
UGC 4881 (also known as The Grasshopper) is a pair of interacting galaxies, UGC 4881A and UGC 4881B. [1] They are located in the constellation Lynx, some 500 million light-years away.
He also discovered NGC 5195, the companion galaxy that makes M51 (the Whirlpool Galaxy) so distinctive. Méchain never set out to observe deep-sky objects. Like Messier, he was solely interested in cataloguing objects that might be mistaken for comets ; having done so, he was the second-most successful discoverer of comets of his time, after ...
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 is almost exactly at the galactic rotational ...
