James Webb Telescope Discovers Lemon-Shaped Exoplanet

James Webb Telescope Discovers Lemon-Shaped Exoplanet

Scientists using the James Webb Space Telescope have found a very unusual planet called PSR J2322-2650b.

This planet is about the size of Jupiter but is stretched into a lemon shape because it is very close to a special kind of star called a pulsar.

The planet orbits this star very quickly, completing a full orbit in just 7.8 hours.

The planet's atmosphere is also very different from what scientists expected.

It has a lot of helium and carbon but very little oxygen or nitrogen.

This means there is no water, methane, or carbon dioxide in its atmosphere.

Instead, there might be soot clouds and even diamonds deep inside the planet.

This discovery is important because it shows that planets can be much more diverse than we thought, and it challenges our current understanding of how planets form.
