Are "Habitable" Exoplanets Really Habitable?

New findings show that the stellar wind from red dwarfs may induce such catastrophic atmospheric loss from otherwise habitable exoplanets that life could not evolve. More . . .

Water Worlds Don't Stay Wet for Very Long

When hunting for potentially habitable exoplanets, one of the most important things astronomers look for is whether or not exoplanet candidates orbit within their star’s habitable zone. This is necessary for liquid water to exist on a planet’s surface, which in turn is a prerequisite for life as we know it. However, in the course of discovering new exoplanets, scientists have become aware of an extreme case known as “water worlds“.
