Pulsars Rewrite the Rules

For decades, astronomers thought they knew that pulsars broadcast their signatight beams of radio waves fired from near the surface, close to the magnetic poles. A new study of nearly 200 of the fastest spinning pulsars in the universe has just turned that idea on its head. It turns out these extraordinary objects are broadcasting from two completely separate locations at once, and one of them lies right at the outer edge of their magnetic grip on space itself.
