Some things we see in space appear to outpace light. Donāt panic: nothing would be breaking the cast-iron law of physics that rules out anything moving faster than light. It is only an optical illusion. That said, there are real phenomena out there in the cosmos that create similar illusions.
Astronomers have long spotted these superluminal illusions, once dismissed as curiosities. But we are now realising some can reveal hidden, surprising details about the universe that no other observation can such as the inner workings of some of the most mysterious phenomena in our cosmos. And with the opening of the Vera C. Rubin Observatory, we might be on the cusp of seeing these fleeting illusions much more often and continue learning to harness these bizarre optical illusions to understand the mysteries of neutron stars, gamma ray bursts and more.
