Some 230 million light-years from Earth, there’s a black hole going places. These extraordinarily dense objects are usually found sitting at the center of a galaxy violently gobbling up matter, so it was a surprise when astronomers spotted this one moving out of step with its resident galaxy.
About 15,000 light-years away from Earth, a cloudy patch of space within our galaxy produces ultra-bright flashes of gamma radiation like clockwork. That’s not all—researchers found the unusual “heartbeat” coming from this cosmic gas cloud is beating along in time with the pulses of a black hole, located a whopping 100 light-years away from it. Researchers remain puzzled as to what the unusual long-distance relationship is between the two.
