A prominent feature of science fiction and movies, super massive black holes are the biggest possible black hole known today.
They are not uncommon and found in or near the central portion of all known large galaxies.
Super massive black holes are distinguished from their regular black hole counterparts because of the lower than average density. Super massive black holes are theorized to have a smaller density than water.
An article published by a professor of Physics at Cardiff university detailed just how astronomers were able to catch a super massive black hole in action.
Using microwave detection and the 66 antennae of the Atacama Large Millimeter Array, scientists were able to detect emissions from all over the universe. With this technology a super massive black hole was caught consuming large clouds of gas.
The gas clouds were barreling towards the black hole at an estimated speed of 530 thousand miles per hour.
