The Black Hole - A mystery to be solved in the future!
The IPhO 2016 Logo illustrates an active galactic nucleus. They are the most energetic objects known in our universe, yet they remain a mystery. These powerful sources of energy consist of a super massive and extremely dense object which can exceed a billion times the mass of our Sun. The enormous gravitational attraction means even light cannot escape from the innermost part - the super massive black hole.
When gas is spinning inwards into a black hole, an enormous amount of gravitational energy is released. The gas accelerates to very high velocities, heats up and releases an enormous amount of energy in the form of light. This process can outshine an entire galaxy of several billion stars.
