Scientists Intrigued by Radio Signals Coming From Comet

It’s not just interstellar comet 3I/ATLAS that’s been catching the attention of scientists.

Comet 12P/Pons-Brooks, which was first discovered in 1812 and visits the Earth roughly every 71 years, has been found to be emanating intriguing radio signals.

As detailed in a new paper published in the journal Astronomy & Astrophysics, a team of astronomers led by the Shanghai Astronomical Observatory of the Chinese Academy of Sciences used data collected by the Tianma Radio Telescope during its latest approach to the Sun last year.

The comet is a Halley-type comet, meaning it’s an icy object that has an orbital period of anywhere between 20 and 200 years. Before 2024, its last closest pass was in 1954. Each time it’s come by for a visit, scientists have observed it giving off multiple outburst
