For decades, astronomers have been puzzled by strange “zebra stripe” patterns in radio waves from the Crab Pulsar — bright bands separated by complete darkness. Now, new research suggests the answer ...

BTS skipped the measurement entirely. On March 21, 2026, they played a free concert at Gwanghwamun—their first performance as a complete group in six years—and in doing so, commandeered the entire ...
