3I/ATLAS Has a HEARTBEAT — And Scientists Are Running Out of Time | Brian Cox for Sleep

3I/ATLAS was already strange — but now, astronomers have detected something no interstellar object should have: a rhythmic, repeating “heartbeat” signal pulsing every few hours.
Its timing is precise. Its energy output is rising. And its source remains completely unknown.

In this 1-hour Brian Cox sleep documentary, drift through the calm, cinematic breakdown of what scientists are observing: thermal pulses that should be impossible, synchronized energy spikes, and a pattern that appears to be accelerating as 3I/ATLAS moves deeper into the inner solar system.

Let Brian Cox’s serene narration guide you through the science, the speculation, and the growing concern as researchers race to understand this cosmic metronome before it reaches its next critical point.

Perfect for deep sleep, cosmic curiosity, and peaceful exploration of the unknown.
