Ever wandered what the biggest Black Hole is called? or how far away it is? The Universe is vast and Beautiful, but in most cases unknown and terrifying. Its ever expanding blackness filled with tiny bright lights surrounding our little water covered Planet makes you realise how small we really are. It's full of protons, neutrons and electrons that bind together making stars and planets, you and the very device that you are watching this video on. Astronomers call this Baryonic Matter. Along with this very familiar matter is Dark matter and dark energy which you cannot see. But among all of this, is something terrifying, something that we cannot touch or see, and something that we have a hard time even comprehending. A Black Hole, a swirling Vortex where gravity traps anything, including light and won't let it escape. The gravity is so strong because when a large star collapses in on itself its matter becomes compressed and squeezed into a tiny space. They are invisible because light cannot get out, but space telescopes with special tools can help find them by observing how stars act differently when close to a black hole. They can be large or small; Scientists think that there are black holes as small as atoms, but have the mass of a mountain. The biggest black holes are called SMBH or super massive black holes. These are the largest types and can be hundreds of thousands of solar masses. Super massive black holes can be more commonly found at the centre of galaxies. The Milky Way's galactic centre contains an intense compact radio source that emits synchrotron radiation, this is 26,000 light years away from our solar system in a region called Sagittarius A, which coincides with a super massive black hole. Scientists in Germany have confirmed that the black hole is on the order of 4 million solar masses. Donald Lynden-Bell and Martin Rees hypothesized in 1971 that the centre of the Milky Way galaxy would contain a super massive black hole. This was, therefore the first that was ever discovered. But the biggest and most powerful ever discovered black hole to date is located at RX J1532, a galaxy cluster 3.9 billion light years away. This distant galaxy is harbouring what can only be described as an ultra massive black hole. NASA has released images of the bright cluster using x ray data and optical data from Hubble; they believe that the ultra massive black hole weighs as much as 10 billion times more than our sun. But there is also something strange happening around the black hole, a glowing gas. This bright gas should cool down and drop in pressure, meaning that it sinks to the middle of the galaxy and should form trillions of stars. But the reason the stars cant form is that there are two huge cavities either side of the large elliptical galaxy at the cluster's centre the size of the milk way. These cavities are aligned with the jets coming from the black hole emitting huge amounts of power to drill through the gas and creating immense shock waves. The power needed to generate them is among the largest known in galaxy clusters. The expanding cavities and the release of energy by sound waves reverberating through the hot gas provide a source of heat that prevents most of the gas from cooling and forming new stars. Also confusing astronomers is if the black hole is producing jets, what is fuelling it? Well the x ray emissions show that there isn't matter being dragged in which could mean that the black hole is actually 0ver 10 billion solar masses. Such a black hole should be able to produce powerful jets without consuming large amounts of mass, resulting in very little radiation from material falling inwards. Or the black hole is actually smaller but spinning extremely fast which can produce more powerful jets than a slowly spinning black hole when consuming the same amount of matter. So whatever is fueling this black hole and causing the strange happenings within the galaxy, this is truly the biggest most powerful and most terrifying of all the black holes discovered to date.
