Exoplanet PSR J2322-2650b and Pulsar (Artist’s Concept)

llustration labeled “artist’s concept” at right bottom corner. At left bottom corner, a partially illuminated, lemon-shaped exoplanet appears against a black background. This planet is most brightly illuminated at its elongated tip on its right side. On the left side, which is wider, the planet trails off into the darkness of the background. The planet is colored in varying, mottled shades of red, light pink, and fuchsia. Most of the pink occurs closest to the tip, while most of the fuchsia is at the top and bottom edges. At right top corner, a white beam emanates diagonally, oriented from 10 o’clock to 4 o’clock, from either side of a small, glowing, white star.

This artist’s concept shows what the exoplanet called PSR J2322-2650b (left) may look like as it orbits a rapidly spinning neutron star called a pulsar (right). Two radio beams are emitted from the pulsar’s magnetic poles, whipping around like a beam from a lighthouse. Gravitational forces from the much heavier pulsar are pulling the Jupiter-mass world into the shape of a lemon. This planet, studied with NASA’s James Webb Space Telescope, appears to have an exotic atmosphere unlike any ever seen before. How the planet came to be is a mystery.

Exoplanet PSR J2322-2650b (Artist's Concept)

This artist’s concept shows what the exoplanet PSR J2322-2650b may look like. Gravitational forces from the much heavier pulsar it orbits are pulling the Jupiter-mass world into this bizarre lemon shape.

Against a black background, a white beam emanates diagonally, oriented from 11 ou2019clock to 5 ou2019clock, from either side of a small, glowing, white star. To the right of this star, a partially illuminated, lemon-shaped exoplanet appears. This planet is most brightly illuminated at its elongated tip on its left side. The planetu2019s right side, which is wider, appears to trail off into the darkness of the background. The planet is colored in varying, mottled shades of red, light pink, and fuchsia. Most of the pink occurs closest to the tip, while most of the fuchsia is at the top and bottom edges.

Exoplanet PSR J2322-2650b Orbiting a Pulsar

This animation shows an exotic exoplanet orbiting a distant pulsar, or rapidly rotating neutron star with radio pulses. The planet, which orbits about 1 million miles away from the pulsar, is stretched into a lemon shape by the pulsar’s strong gravitational tides. NASA&rsqu...
