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 ...
Held Thursday through Sunday, July 27-30, more than 50,000 people attended the convention, said Jessica Holt, director of public relations and international tourism at the Greater Raleigh ...
IC 1101 is a class S0 supergiant lenticular galaxy at the center of the Abell 2029 galaxy cluster.It has an isophotal diameter at about 123.65 to 169.61 kiloparsecs (400,000 to 550,000 light-years).
Rich pioneered the modern study of the central bulge/bar stellar population of the Milky Way galaxy, obtaining the first spectroscopy and metal abundances [7] for stars in the Galactic bulge, showing an average metal content similar to that of the Sun and an abundance distribution following the "simple" closed box model of chemical evolution; this required the central bulge of the Milky Way to ...
It is not known how much further the wall extends due to the light absorption in the plane of the Milky Way galaxy where Earth is located. The gas and dust from the Milky Way (known as the Zone of Avoidance ) obscure the view of astronomers and have so far made it impossible to determine if the wall ends or continues on further than they can ...
The Milky Way galaxy is a member of an association named the Local Group, a relatively small group of galaxies that has a diameter of approximately one megaparsec. The Milky Way and the Andromeda Galaxy are the two brightest galaxies within the group; many of the other member galaxies are dwarf companions of these two. [176]
