A newly discovered exoplanet, PSR J2322-2650b, orbiting a millisecond pulsar, exhibits bizarre features such as a lemon shape, a carbon-rich atmosphere with potential diamond rain, and an unusual atmospheric rotation, challenging current understanding of planetary formation and evolution.
An unusual exoplanet called PSR J2322-2650b, located 2,000 light years away and shaped like a lemon due to the intense gravity of its pulsar host, exhibits unique characteristics including a helium-and-carbon atmosphere where rain could turn into diamonds, making it potentially a new type of celestial object.
Astronomers using the James Webb Space Telescope have discovered a unique, lemon-shaped exoplanet called PSR J2322-2650b, orbiting a pulsar at a very close distance. The planet has an unusual composition dominated by helium and carbon, with surface temperatures up to 3,700°F, and may represent a new class of cosmic object due to its peculiar shape and atmosphere. Its origins are uncertain, raising the possibility of a new type of celestial body.
