There was one about 10:30 last night, right after the news.
None has been discovered today, but it's still early.
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.
They are in almost every galaxy in our universe and there are an estimated 100 billion galaxies.
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.
Super-massive black holes are found at the center of most galaxies, including our Milky Way. These black holes have masses millions to billions times that of our Sun, and their gravity plays a vital role in the dynamics of galaxies. Scientists believe they form and grow through accretion of matter and mergers with other black holes.
There are three main types of black holes: stellar black holes, which form from the collapsed cores of massive stars; supermassive black holes, found at the centers of galaxies and containing millions to billions of times the mass of the sun; and intermediate black holes, with masses between stellar and supermassive black holes.
That's the current best guess; the formation of extremely powerful black holes in the centers of many galaxies. It's possible that when the central black hole in the Milky Way was forming, our own galaxy might have shined like a quasar. This may be why we never see any aliens in space; any civilization that existed then might have been exterminated by the radiation released when the central black hole formed. Earth's biosphere formed after that, and we might be one of the first spacefaring species since.
Black holes can technically be any where. Some scientists believe that there is a black hole in the center of our galaxy along with many other galaxies. Because black holes are so difficult to detect, they can be very dangerous.
Probably only one - at the centre.
All galaxies have supermassive black holes in their centers.
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.
Yes, black holes are known and regarded by many scientists, astronomers, and physicists.
Yes, probably many of them. We believe that there is a supermassive black hole at the center of the Milky Way galaxy; that there are probably similar suoermassive black holes at the centers of many large galaxies.
stellar, supermassive, miniature
Our galaxy contains a supermassive black hole at the center and probably several million stellar mass black holes scattered throughout.
Super-massive black holes are found at the center of most galaxies, including our Milky Way. These black holes have masses millions to billions times that of our Sun, and their gravity plays a vital role in the dynamics of galaxies. Scientists believe they form and grow through accretion of matter and mergers with other black holes.
Probably yes, although we cannot be certain. The gas and dust clouds prevent us from seeing the center. Scientists believe that there may be a supermassive black hole at the center of the Milky Way, as there appear to be supermassive black holes at the centers of many large galaxies.
Unknown - As they can't easily be detected, and most of them are expected to have been formed upon the onset of the Big Bang. Astronomers estimate that in our region of the Universe, there are some 100 billion supermassive black holes. But this does not account for the lesser size black holes, of which there is estimate to be a much larger number.
It is not known how many black holes exist. One of the main reasons is that, if matter is not actually falling into the black hole, it is impossible to detect.
Probably the supermassive black holes that are believed to be at the centers of many (perhaps most) large galaxies. These may be related to quasars.
