Unexpected conclusion, at least if we had never thinking at a such thing: some other discovered planets outside our solar system may have conditions more suitable for life than Earth. Even their sun may be better than our. In other words, Earth is not necessarily the best planet in the universe. A study led by Washington State University scientist Dirk Schulze-Makuch details characteristics of potential “superhabitable” planets, that include those that are older, a little larger, slightly warmer and possibly wetter than Earth.

The 24 top contenders for superhabitable planets are all more than 100 light years away. “With the next space telescopes coming up, we will get more information, so it is important to select some targets,” said Schulze-Makuch. For the study, Schulze-Makuch, a geobiologist with expertise in planetary habitability teamed up with astronomers Rene Heller of the Max Planck Institute for Solar System Research and Edward Guinan of Villanova University. “It’s sometimes difficult to convey this principle of superhabitable planets because we think we have the best planet,” said Schulze-Makuch. There’s no confirmation that life exists on these planets.
