| Scientists, including one of Indian-origin, have obtained the most detailed map of a super-Earth planet for the first time, that consists of two halves - one that is almost completely molten and the other mostly solid.
Using data from NASA's Spitzer Space Telescope, researchers found that temperatures on the hot side can reach 2,500 degrees Celsius, while temperatures on the cool side are around 1,100 degrees Celsius.
The latest findings tell us the planet has hot nights and significantly hotter days. This indicates the planet inefficiently transports heat around the planet," said study lead author Brice Olivier Demory of the University of Cambridge in the UK.
"We propose this could be explained by an atmosphere that would exist only on the day side of the planet, or by lava flows at the planet surface," said Mr Demory.
The toasty super-Earth 55 Cancri e is relatively close to Earth at 40 light-years away. It orbits very close to its star, whipping around it every 18 hours
