- For decades, astronomers have been puzzled by strange "zebra stripe" patterns in radio waves from the Crab Pulsar, a mystery that has persisted for over 20 years, as reported by Sci.News.
- New research suggests these unique patterns are caused by a cosmic "tug-of-war" between the pulsar's gravity and its surrounding plasma.
- The pulsar's plasma spreads light apart, while gravity bends it back together, creating interference patterns that form the distinct stripes, according to the University of Kansas.
- This discovery marks the first observed instance where both gravity and plasma collaboratively shape a signal from space.
- Professor Mikhail Medvedev, a theoretical astrophysicist at the University of Kansas, led the research that refined earlier models to fully explain the phenomenon.
- The stripes are "absolutely distinct with complete darkness between them," a unique characteristic not seen in other pulsars, as quoted by Professor Medvedev in reports from Sci.News.
Crab Pulsar's Zebra Stripes Explained
For over two decades, mysterious "zebra stripe" patterns in radio waves from the Crab Pulsar have baffled astronomers, but new research now reveals they are caused by a cosmic "tug-of-war" between the pulsar's gravity and its surrounding plasma. This groundbreaking discovery, led by the University of Kansas, marks the first time gravity and plasma have been observed collaboratively shaping a signal from space, explaining the unique interference patterns.
