Summary:
- Astronomers have detected a radio signal from the interstellar comet 3I/ATLAS, also known as Borisov. This comet is the second known interstellar object to visit our solar system, after 'Oumuamua.
- The radio signal suggests that the comet may have an active nucleus, meaning it is still releasing gas and dust as it travels through space. This could provide valuable information about the composition and structure of interstellar objects.
- Studying interstellar comets like Borisov can help scientists better understand the formation and evolution of our solar system, as well as the wider universe beyond our planet.
