Researchers have developed the Smaller Than Earth Habitability Model (STEHM) to assess which planets can maintain ...

In Star Trek, you might hear a character describe a planet as "M-Class." Here's what that designation means, and how it ...

The planets around white dwarf stars might provide long-term homes for alien life, but they suffer from a fatal overheating problem. Who's going to rescue them? According to new research, it's none ...

Researchers studied the orbits of 150 planets in the Milky Way and found that many of them were at the right temperature to have life. For generations, scientists have known that the Milky Way ...

Do aliens sleep? You may take sleep for granted, but research suggests many planets that could evolve life don’t have a day and night cycle. It’s hard to imagine, but there are organisms living in ...

We're getting closer and closer to finding a real Earth-like exoplanet. But finding one is only half the battle. To truly know if we're looking at an Earth analog somewhere else in the galaxy, we have ...

The habitable zone : basic concepts / S.R. Kane -- Exoplanets : criteria for their habitability and possible biospheres / J.L. Grenfell et al. -- The habitable zone and the generalized greenhouse ...

The old adage that it's easier to prove a negative could play a crucial role in characterizing nearby exoplanets that could harbor life. The idea is that looking for earth-like planets is tough enough ...

How much water do habitable exoplanets need for life as we know it to exist? This is what a recent study published in The Planetary Science Journal hopes to address as a team of scientists ...

While a planet can orbit around a Sun-like star and sit comfortably within its habitable zone, it could also potentially not meet any of the fundamental requirements for sustaining life. Specifically, ...
