SUMMARY: New images taken by the Chandra X-Ray Observatory show galaxies in an energetic phase in their development. Supermassive black holes at their centres are transferring a significant amount of energy into the gas surrounding the galaxies. Astronomers believe that this is just a stage in longer cycle where gas cools to form galaxies, which then merge and create a supermassive black hole. Jets of hot gas blast away from the black hole sweeping away all matter, giving the gas a chance to cool back down and then the cycle starts all over again.
