Yes. Some galaxies, particularly irregular galaxies, appear to lack supermassive black holes.
No, only small ones, the supermassive ones are at the centre of galaxies.
Supermassive black holes found at the centers of galaxies are related to the stellar velocity dispersion in the bulge of the galaxy. To a lesser degree, there is also a correlation with the mass of the galaxy.
No, there are many black holes in space. They reside throughout the universe and come in different sizes, ranging from stellar-mass black holes to supermassive black holes found at the centers of galaxies.
A black hole has a much larger mass than a planet. The mass of a black hole, however, is contained in a point that is smaller than some fundamental particles. The event horizon of a typical stellar mass black hole is much smaller than any planet, but the event horizons of supermassive black holes are much larger.
As of now, astronomers have identified supermassive black holes in the centers of most galaxies, including our own Milky Way. Estimates suggest there are around one billion supermassive black holes in the observable universe. These black holes are millions to billions of times more massive than our Sun.
Yes, many galaxies have supermassive black holes at their centers.
Yes
Not all galaxies have black holes in their centers, but many large galaxies, including our own Milky Way, are believed to have supermassive black holes at their centers.
Not all galaxies have black holes. While many galaxies, including our own Milky Way, have supermassive black holes at their centers, there are also galaxies that do not have black holes. The presence of a black hole in a galaxy depends on various factors such as the size and age of the galaxy.
Not every galaxy has a black hole at its center. While many galaxies do have supermassive black holes at their centers, there are also galaxies that do not have black holes.
Most black holes form when massive stars exhaust their fuel and their cores collapse. There are also supermassive black holes at the centers of most galaxies. Scientists are not sure how supermassive black holes form.
Black Holes are scattered throughout the cosmos. It is theorised that there are supermassive black holes at the centre of galaxies such as ours (The Milky Way).
Not sure what you mean. M60 is a galaxy. Just about all galaxies have supermassive black holes in their center - and lots of smaller black holes. The supermassive black hole in M60 is estimated to have 4.5 billion solar masses - one of the largest known black holes.
Most or all galaxies appear to have supermassive black holes at their centers and probably have stellar mass black holes scattered throughout.
Supermassive black holes can be found at the center of most galaxies, including our own Milky Way galaxy.
All galaxies have supermassive black holes in their centers.
Quasars are related to supermassive black holes in the center of galaxies.
