Do irregular galaxies have black holes?
The galaxy known as NGC 6240 is known as an irregular galaxy due to its particular shape. Until now, astronomers have assumed that it was formed by the collision of two smaller galaxies and therefore contains two black holes in its core.

Correspondingly, what does the ngc stand for in galaxies? New General Catalogue of NGC catalog, in full A New General Catalogue of Nebulae and Clusters of Stars, being the Catalogue of the Late Sir John F. W. Herschel, Bart., revised, corrected, and enlarged, basic reference list of star clusters, nebulas, and galaxies.
Regarding this, is comet a galaxy?
The Comet Galaxy, a spiral galaxy located 3.2 billion light-years from Earth, in the galaxy cluster Abell 2667, was found with the Hubble Space Telescope. This galaxy has slightly more mass than our Milky Way. Comet Galaxy Distance 3.2 billion light-years Apparent magnitude (V) 18.7 Characteristics Type dIrr 10 more rows One may also ask is the sun a population 1 star? The Sun is considered Population I, a recent star with a relatively high 1.4 percent metallicity. Note that astrophysics nomenclature considers any element heavier than helium to be a "metal", including chemical non-metals such as oxygen.
What is M51 in the sky?
The graceful, winding arms of the majestic spiral galaxy M51 appear like a grand spiral staircase sweeping through space. They are actually long lanes of stars and gas laced with dust. Such striking arms are a hallmark of so-called grand-design spiral galaxies. In respect to this, what happened to m81 and m82? Their last go-round lasted about 100 million years and likely raised density waves rippling around M81, resulting in the richness of M81's spiral arms. M82 was left with violent star forming regions and colliding gas clouds so energetic the galaxy glows in X-rays.
How far apart are M81 and M82?
12 million light-years M81 (on the left), a "face-on" spiral galaxy, and M82 (on the right), seen "edge-on," are a pair of galaxies in the constellation Ursa Major, near the "Big Dipper." The apparent separation of the galaxies is 31 arc-minutes but at a distance of 12 million light-years, their actual distances from each other is 150,000
- Do spiral galaxies have black holes?
The sea ice keeps the surface cooler. As much as 90 percent of the incoming solar radiation is reflected by snow, which has a higher albedo than sea ice. It helps to insulate the sea ice, keeping it cold and delaying ice melt in the summer.
