The alien planet 55 Cancri e circles close to a star 40-light-years from Earth and may ooze with supercritical fluid. See stunning views of what it may look like.

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.

Twice as big as Earth, the super-Earth 55 Cancri e was thought to have lava flows on its surface. Now, a new analysis finds this planet likely has an atmosphere whose ingredients could be similar ...

NASA has been studying a planet called 55 Cancri e - sort of like Earth, but much closer to its star, with temperatures hot enough to melt and vaporize rocks and possibly oceans of lava, with ...

NASA scientists have potentially uncovered evidence of atmospheric gases surrounding 55 Cancri e, a hot rocky exoplanet orbiting a star similar to our Sun located about 41 light-years away in the ...

While 55 Cancri e has been previously identified to potentially possess an atmosphere comprised of volatiles (nitrogen, oxygen, and carbon dioxide) using the now-retired NASA Spitzer Space Telescope, ...

Called a “Super Earth” because it’s roughly twice the size of our planet, 55 Cancri e is mighty hot. It orbits its star so closely that it’s tidally locked, meaning that the same side of ...

The so-called super Earth — known as 55 Cancri e — is among the few rocky planets outside our solar system with a significant atmosphere.

Researchers may have detected atmospheric gases surrounding 55 Cancri e, a hot rocky exoplanet 41 light-years from Earth. This is the best evidence to date for the existence of any rocky planet ...

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.
