Using the James Webb Space Telescope , astronomers have discovered that a scorching hot lava planet, believed to be composed of diamond, grew a second atmosphere — and that was after its star destroyed its first atmosphere., is located around 41 light-years from the solar system and has a width almost twice that of Earth and a mass around nine times greater than our planet.
As the planet was investigated further, scientists also learned about its 0.7 Earth-day orbit and carbon composition. Then, in 2016, theFirst, the super-Earth could be a lava world atop which a thin, vaporized silicate atmosphere exists. It'd be made of the planet's volatiles and chemical compounds like carbon, nitrogen, hydrogen and sulfur that can be easily lost due to irradiation from its star.
He explained that gas dissolves in 55 Cancri's global lava ocean, constantly"bubbling out" to form the secondary atmosphere.
