An article published in The Astrophysical Journal Letters reports the results of a study of a gas giant exoplanet cataloged as PSR J2322-2650b, which has a completely abnormal atmosphere composed above all of helium and carbon. A team of researchers used observations conducted with the James Webb Space Telescope to study the atmosphere of this exoplanet, which has a mass similar to Jupiter’s and has a distance from its star that is only one-hundredth of the Earth’s distance from the Sun. The star is a pulsar, adding another unusual element to the system. PSR J2322-2650b can’t be explained by current models of planetary formation.
