An international team, including researchers from Penn State, has unveiled the discovery of a potentially habitable "super-Earth" less than 20 light-years from our solar system, marking a significant ...

In a secluded corner of the Lynx constellation, just 18 light-years from our planet, astronomers have found a stunning jewel—a planet around a tiny red dwarf star that may have the right conditions to ...

For the first time in years, astronomers are seriously talking about adding a new member to the solar system’s planetary family. I’m not talking about reviving Pluto’s status, but about a potential ...
