NASA finds its first 'super-Earth' exoplanet with an atmosphere, Astronomers at NASA, alive with the ESA and the University College London, appear Tuesday that they accept apparent a "super-Earth" exoplanet with an atmosphere for the aboriginal time. The Hubble telescope's Wide Field Camera 3 (WFC3) aboriginal spotted the planet, dubbed 55 Cancri e, which is alone about 40 ablaze years away. Super-earths are artlessly bouldered planets that are bigger than the Earth -- in this case, eight times bigger. They're broadly believed to be the a lot of accepted blazon of bouldered planet in the galaxy.
"This is a actual agitative aftereffect because it's the aboriginal time that we accept been able to acquisition the ashen fingerprints that appearance the gases present in the atmosphere of a super-Earth," UCL PhD apprentice Angelos Tsiaras said in a statement. "The observations of 55 Cancri e's atmosphere advance that the planet has managed to adhere on to a cogent bulk of hydrogen and helium from the billow from which it originally formed."
Unfortunately, 55 Cancri e apparently doesn't abutment life. Its atmosphere appears to be comprised about absolutely of hydrogen and helium with no traces of water. Plus, the planet is so abutting to its brilliant that a year there lasts 18 Earth-hours and the apparent of the planet can get as hot as 2,000 degrees C.
