In a seminar, she heard about 55 Cancri e as a potentially carbon-rich planet, so high in temperature and pressure that its interior could contain a large amount of diamond.

Astronomers also thought 55 Cancri e contained a substantial amount of super-heated water, based on the assumption that its chemical makeup was similar to Earth’s, Madhusudhan said.

A thick atmosphere has been detected around a planet that's twice as big as Earth in a nearby solar system, researchers reported Wednesday. The so-called super Earth — known as 55 Cancri e ...

With the help of NASA's new James Webb Space Telescope, scientists are learning more about exoplanet "55 Cancri e" -- and it's a scorcher.

What is 55 Cancri e? It’s an exoplanet or extrasolar planet—a planet outside the solar system—spotted by ASTERIA around a Sun-like double star called 55 Cancri in the constellation of Cancer.

Planet Full Of Diamonds Known as 55 Cancri-E, the planet has been classified as a super-earth. A large part of which may be made up of carbon structures like diamonds and graphite.

The 55 Cancri e — abbreviated 55 Cnc e — is roughly 3,600 degrees Fahrenheit and is nicknamed the "hell planet" because of its proximity to its sun, according to researchers.

As 55 Cancri e passed behind its host star, its dayside — the half of the planet that constantly faces the searing heat of its star — briefly pointed toward Earth.

Now, astronomers at MIT have revealed that exoplanet 55 Cancri e — once thought to be a dry, rocky world — may be literally oozing with supercritical fluids.
