How a twin Earth could detect Earth

A research team led by Dr. Sofia Sheikh of the SETI Institute, in collaboration with the Characterizing Atmospheric Technosignatures project and the Penn State Extraterrestrial Intelligence Center, set out to answer a simple ...

How well could Earth life survive on exoplanets?

Astronomers have found some pretty wild exoplanets. Some are balls of lava the temperature of hell, one is partially made of diamond, and another may rain molten iron. However, not all exoplanets are this extreme. Some are ...

Could ocean worlds support life?

There might be a type of exoplanet without dry land. They're called "Hycean" worlds, a portmanteau of "hydrogen" and "ocean." They're mostly or entirely covered in oceans and have thick hydrogen atmospheres.
