Small stellar corpse shoots beam of matter and antimatter trillions of miles into deep space

PSR J2030+4415 isn’t just any pulsar. 

That much is certain, thanks to the absolute colossus of a beam that astronomers have discovered erupting from the pulsar’s heart. (A pulsar is a type of neutron star — the ultradense remnants of an exploded star — that emit two beams of light as they spin, like a lighthouse.) And in this case, that beam is packed with matter and antimatter and spans 40 trillion miles (64 trillion kilometers) from end to end, long enough to eclipse the entire solar system.
