But a signal that repeated every 16 days was recently discovered, although the signal was more random than periodic. But in December 2019, CHIME detected the periodic, heartbeat-like signal.

All of these systems add non-periodic signals to the power system. Protection communications usually use frequencies in the hundreds-of-hertz range transmitted from one location to another and ...

These signals have the capacity to captivate attention across vast interstellar distances, distinguishing themselves from non-periodic signals and requiring significantly lower energy compared to ...

"Self-oscillating materials convert a non-periodic signal into the material's periodic motion," Balazs explained. "Using our computer models, ...

Astronomers have detected a mysterious radio signal that is pulsing rhythmically "like a heartbeat" in deep space. The signal, named FRB 20191221A, is a fast radio burst (FRB) — an intensely ...

It also has the clearest periodic pattern ever seen in an FRB, according to MIT. Advertisement: While this signal can be pinpointed to a specific distant galaxy, its exact source is not known.
