Chandra scientist have released images and data that suggest that they have discovered the most powerful eruption ever seen in the Universe. It appears to have been found in a galaxy close to the centre of our cluster. The x-ray cavities that have been discovered appear on opposite sides of the large galaxy under question and there presence indicates that a large eruption from the galaxies central supermassive black hole caused them. The suggestion is that a vast amount of gas fell onto the black hole and once releasing large jets which pushed through the galaxy and into the hot interglatic gas. As these jets moved the gas it caused these cavities to form. This is rather interesting and seems quite feasible.
