A telescope in Canada picked up 13 fast radio bursts (FRBs) coming from a . That’s an intense long-distance message. Such an event has happened before, but only once, and that time the FRBs were picked up by a different telescope. What does it all mean? It’s fun to think the bursts could originate from an alien spaceship or populated planet, but scientists tend to think along other lines. For example, the source could be a neutron star with a very strong magnetic field, or two neutron stars merging together. Whatever the reason, it’s pretty amazing that Earth telescopes can pick up something that’s travelled 1.5 billion light years.
