Breakthrough Listen Detects Rhythmic Signal by Sagittarius A*

Researchers at Columbia University, working with Breakthrough Listen, may have identified a millisecond pulsar near Sagittarius A*. The rhythmic signals could act as ultra-precise cosmic clocks in one of the most extreme gravitational environments known.If confirmed, the discovery would enable new tests of Einstein’s general relativity under intense spacetime curvature—offering rare insight into gravity at the galactic center.Thank you for listening to Bedtime Astronomy — your guide to the cosmos.
