US EditionLemon-Shaped World Is the Most Stretched-Out Planet Ever Seen
PSR J2322-2650b orbits a pulsar every 7.8 hours, exhibiting a lemon shape and a carbon-rich atmosphere unlike any other, challenging existing planetary formation theories.
- Using NASA's James Webb Space Telescope, astronomers found PSR J2322-2650b, a Jupiter-mass world orbiting its pulsar every 7.8 hours just one million miles away, with a helium and carbon atmosphere distorted into a lemon shape.
- The system centers on a millisecond pulsar that emits intense gamma-rays but little infrared, letting NASA's James Webb Space Telescope capture a pristine planetary spectrum, and the companion is tidally locked to the pulsar.
- Spectral analysis revealed molecular carbon chains C3 and C2 absorbing at specific wavelengths, with C3 dropping at 3.014 microns, and the dayside reaches 3,700 degrees Fahrenheit.
- Researchers say the discovery published in The Astrophysical Journal Letters challenges planet-formation theories and prompts follow-up observations and modeling.
- NASA's Webb Mission Team said, `Soot clouds likely float through the air, and deep within the planet, these carbon clouds can condense and form diamonds.

James Webb Discovers Planet Shaped Like Lemon
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 when we say say “stretch,” we mean it literally. The roughly Jupiter-mass object, designated PSR J2322-2650b, orbits just one million miles away from its star, or one percent of the Earth’s distance from the Sun, with a single “year” lasting just 7.8 Earth hours. And at suc…
“What the Heck Is This?” – Astronomers Discover Entirely New Type of Exoplanet With Bizarre Atmosphere
Astronomers have discovered a carbon-rich exoplanet with a bizarre atmosphere and shape, orbiting a neutron star under extreme conditions that challenge current models of planetary formation. Scientists working with NASA’s James Webb Space Telescope have identified a previously unknown kind of exoplanet, one whose unusual atmosphere challenges our understanding of how this type of planet [...]
Scientists Discover ‘Black Widow’ Exoplanet That Defies Explanation
Welcome back to the Abstract! Here are the studies this week that defied expectations, broke barriers, made trash into shelter, and lived to swear another day.First, there’s a giant, lemony, diamond-studded, black widow in space. I’ll explain. Then: electrons get ready for a close-up, the ultimately tiny home, and why expletives are the hottest new workout hack. As always, for more of my work, check out my book First Contact: The Story of Our Ob…
NASA amazed after discover of strange lemon-shaped planet
A new discovery made using the James Webb Space Telescope (JWST) may be the weirdest exoplanet yet. The planet, designated PSR J2322-2650b, has an atmosphere unlike any other yet discovered, and the team behind the discovery can't explain how such a planet came to be.
