US EditionLemon-Shaped World Is the Most Stretched-Out Planet Ever Seen
PSR J2322-2650b orbits a pulsar in under eight hours with a helium- and carbon-rich atmosphere devoid of hydrogen, oxygen, and nitrogen, challenging planet formation theories.
- Astronomers discovered an exoplanet with an ellipsoid, lemon-like shape and an atmosphere containing unusually high amounts of molecular carbon instead of expected molecules like water and methane.
- The planet, named PSR J2322-2650b, orbits a dense stellar remnant called a pulsar that is crushing down to a width of around 12 miles and spinning as fast as 700 times per second.
- This extreme carbon enrichment poses a challenge to the current understanding of such 'black widow' systems, where a pulsar destroys its companion star, leaving behind a small, dense remnant.

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.
NASA's James Webb space telescope has discovered a rare type of exoplanet, that is, a planet outside our solar system, whose atmospheric composition "defines our understanding of how it was formed," as revealed by the United States space organism in a statement. Officially called PSR J2322-2650b, this object with the mass of Jupiter seems to have an exotic atmosphere, dominated by helium and carbon, never seen before, says NASA. It is likely tha…
The gas giant has already generated a great deal of interest in the scientific community.
