Powerful jets of material spewing from the edge of monster black holes may be more likely to arise where two galaxies have merged together, a new study suggests.

Like a cosmic version of Old Faithful (the famous Yellowstone geyser), some black holes at the center of galaxies will spew jets of material into space that stretch for thousands of light-years. You can see an illustration of what these gushing pillars look like in a video of the galaxy crash discovery.

Using data from the Hubble Space Telescope, new research suggests these jets are more likely to be found in galaxies that are the product of galaxy mergers.
