New-found super-Earth likely has volcanoes, atmosphere: NASA
Fresh analysis of an exoplanet twice the size of Earth, thought to have lava flows, has revealed the super-Earth might also have an atmosphere. The tidally-locked exoplanet, discovered by NASA telescopes in 2013, has permanent day and night sides having temperatures of 2,300ÂºC and 1,300ÂºC respectively. The temperature difference would be more extreme if there were no atmosphere, said NASA.
