On May 31, the US National Aeronautics and Space Administration (NASA) said that it is expected to reveal the true face of "super earth" 55 Cancri e with the James Webb Space Telescope in the "next few weeks"

previously, NASA used the Spitzer Space Telescope to discover this "super earth" whose surface was covered with lava. It is located in the cancer constellation, because it is also a rocky planet like the earth, but its surface is covered with lava. Astronomers call it "super hot super earth"

55 Cancri e is twice the size and eight times the mass of the earth. It is about 50 light-years away from the earth and less than 2.4 million kilometers away from the sun like star. This is only 1/25 of the distance between the sun and mercury. It should be clear that the average temperature of mercury is 178 degrees Celsius

compared with 365 days for the earth to orbit the sun, 55 Cancri e takes only 18 hours to orbit the star

nasa said about 55 Cancri e: "because the surface temperature of the planet is much higher than the melting point of typical rock forming minerals, scientists generally believe that the daytime surface of the planet is covered with a lava ocean."

"imagine if the earth is closer and closer to the sun." NASA added, "it is so close to its parent star that it lasts only a few hours a year, so that gravity will permanently fix one hemisphere of the planet in the hot stellar light, while the other hemisphere is in endless darkness." "So close to the parent star that the ocean boiled, the rocks began to melt, and it was all lava rain."

nasa describes "super earth" as a kind of "planets that are different from any planet in the solar system". "It is larger than the earth, but lighter than ice giants such as Neptune and Uranus. It can be composed of gas, rock or a combination of the two. This type of planet is usually twice the size of the earth, and even 10 times the mass of the earth." The initial observations of the Spitzer Space Telescope show that the hottest spot on 55 Cancri e is not necessarily on the side facing the star NASA scientists put forward a theory that this is because the planet has a "dynamic atmosphere that can move heat around"

another theory holds that the rotation of the planet will also produce day and night, so its "surface will heat, melt, or even evaporate during the day, forming a very thin atmosphere that can be detected by the Weber space telescope," NASA said

"at night, the steam will cool and condense into lava drops, and then fall back to the surface, and become solid again as night falls." (Chenchen)
