One of the only reasons we're all able to live our lives on this planet is that Earth was blessed with a robust atmosphere. That's something that not all planets have, and scientists are still a little hazy on exactly what conditions during a planet's formation and the following billions of years result in an atmosphere like ours. Now, a new discovery made by the Hubble Space Telescope suggests that planets that lose their atmosphere may not be doomed and that it may be possible to actually regrow an atmosphere if conditions are just right.
In a new blog post on NASA's website, the space agency explains that images captured by Hubble of the planet GJ 1132 b hint at a very complicated history. The planet, which is a mere 41 light-years from Earth, orbits a red dwarf star and is believed to have begun its life as a "sub-Neptune" gassy world. The radiation from its star stripped it bare, leaving behind a rocky core not much different from a primordial Earth.
