Does a planet just have to be in a star’s habitable zone to be habitable, or are other forces at play? This is what a recent study published in The Astrophysical Journal hopes to address as a team of ...

Understanding planetary habitability is one of the major challenges of the current scientific era. Though traditionally viewed through the lens of our home planet and its evolutionary history, data ...

Hydrogen and helium atmospheres could keep exoplanets warm enough to be habitable for billions of years, even at huge distances from their stars. Astrobiologists normally think of the habitable zone ...
