(Phys.org)—A carbon star is a giant red star nearing the end of its life, with an atmosphere containing more carbon than oxygen. LX Cygni could be an interesting example of an object that is currently in the process of ...
Earth-like planets orbiting other stars in the Milky Way are three times more likely to have the same type of minerals as Earth than astronomers had previously thought. In fact, conditions for making the building blocks of ...
