A study reveals the possibility of water in the hot, rocky outer planets’ atmosphere


The magma absorbs hydrogen from the early atmosphere, interacts together to form water, and then escapes to form an atmosphere of water vapor.

The researchers explained that the atmosphere is what makes life on Earth possible, as it regulates our climate and protects us from harmful cosmic rays, so finding one on an exoplanet could add to the scope of the world capable of hosting life as we know it.

As telescopes document more exoplanets, scientists are trying to discover what they might look like, and scientists expect that many planets may start out like those large planets that are composed of hydrogen atmospheres, but lose their atmosphere when the planet approaches its star and loses hydrogen.
