All Things Space, UFOs, etc.Mysterious ‘heartbeat’ pulsating from interstellar object 3I/ATLAS as it nears Earth Posted on January 19, 2026 by Administrator The mysterious interstellar object 3I/ATLAS has developed a strange ‘heartbeat’ that’s making it glow more brightly as it nears Earth in just two weeks. New telescope observations revealed streams of gas and dust, called jets, blasting out in rhythmic bursts every 16.16 hours precisely, much like a steady heartbeat. Moreover, this pulsing makes the object’s overall glow brighten and dim by 20 to 40 percent in a clean, repeating cycle, which some have claimed suggest 3I/ATLAS is not a naturally-occurring comet.
