NASA’s James Webb Space Telescope has revealed a highly unusual exoplanet, PSR J2322-2650b, orbiting a pulsar in a black widow system.

Unlike typical exoplanets, it is distorted into an oblong “lemon” shape by the pulsar’s intense gravity.

Its atmosphere is dominated by helium and carbon, with molecular carbon present instead of more common compounds like water or methane.

Scientists are puzzled by its formation, as its extreme carbon enrichment doesn’t fit any known planetary formation models, Engadget has reported.

The discovery adds another intriguing mystery to our understanding of the universe.
