Astronomers using the James Webb Space Telescope have discovered an astonishing exoplanet that’s stretching our understanding of what’s possible for these distant worlds. And at such proximity, the extreme gravity of the star — an exotic type known as a pulsar — pulls the entire planet into an oblong shape, like a lemon or a football. “It’s the stretchiest planet that we’ve confirmed the stretchiness of,“ lead author Michael Zhang, an exoplanet scientist at the University of Chicago, told the New York Times. Few pulsars are known to have a planet, let alone one that’s shaped like a lemon, has graphite for clouds, and lacks the elements detected on other worlds. But this has only been observed between a pulsar and another star, not a planet.
