Not much actually. Scientists are still looking into it. What they do know though is that it has eaten up everything around it. Because of that, the supermassive black hole exists in a pitch black, empty area in the center of 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.
That is not yet known for sure. Most large galaxies have a supermassive black hole in their center. It is known how a massive star can convert to a black hole, but it is not currently known how such a black hole would acquire such a huge mass since its creation.
Generally older stars. Most, if not all galaxies have a supermassive black hole at their centre.
Yes. The nearest known black hole is about 3,000 light years away in the system V616 Monocerotis. There is a probably supermassive black hole at the center of the Galaxy, about 26,000 light years away.
Yes. You see, a supermassive blackhole constantly eats away at the galaxy it inhabits. but for clusters the gravitational field is so immense, it already is pulling whole galaxies into its singularity. An example could be that our galaxy, as well as others are being pulled to a phenomenon known as The Great Attraction which could very well be a supermassive black hole.
millions of black holes are in all of the galaxies, and in the center of all large galaxies is an enormous black hole that makes all the stars go around it. the power was a million times greater 350 years ago. this cycle will repeat over again. Scientists have come to believe that there is very probably a supermassive black hole in the center of the Milky Way, and that there may be supermassive black holes at the centers of many galaxies.
The most luminous and distant objects known to science are called quasars and generally accepted to be the nuclei of active galaxies, or in other words supermassive black holes with their relativistic polar jets aimed towards earth.
Please note that the closest known black hole is at a distance of 3000 light-years. Such a black hole cannot directly "have a positive influence". The supermassive black hole in the center of most galaxies is believed to have an important role in the galaxy formation - so it may have had an important influence in the remote past.
Assuming that you are referring to the Milky Way, it is an example of a galaxy - and it happens to be the galaxy that we live in. Galaxies come in many shapes and sizes, but the Milky way is believed to a be a barred-spiral galaxy and has a supermassive black hole at it's core. It is also the only galaxy that is known to harbour life!!!
Timing is everything as astronomers are making discovers all the time. As of an article posted in March of 2012 - Galaxy J1120+0641, containing the most distant supermassive black hole known to science, is so far away that light from it takes over 13 billion years to reach our planet. This means the light astronomers see from this galaxy is just 740 million years after the Big Bang.
The supermassive black hole in the center of our Milky Way is at a distance of about 28,000 light-years. The nearest known stellar black hole is at a distance of about 3000 light-years.
The supermassive black hole that hosts the galaxy NGC 1277, in the constellation Perseus, is currently the largest black hole in our visible universe with a mass equivalent to 17 billion suns. In 2012, astronomers have discovered this small galaxy about 250 million light-years from Earth.
