We tend to think of habitability in terms of individual planets and their potential to host life. But barring outliers like ...

Astronomers have discovered that "super-Earth" planets may exist on wider orbits than previously thought — and this implies these rocky, or "terrestrial," worlds are far more common than was suspected ...

but still less than the masses of gas giant planets. The discovery came after a small extrasolar planet, or "exoplanet," in a wide orbit around its star was discovered, courtesy of a gravitational ...

These observations allowed the team to divide exoplanets into two groups, one that consists of super-Earths and Neptune-like planets and the other comprising gas giants like Jupiter or Saturn.

The new device could reveal exoplanets beyond our solar system that today's telescopes cannot resolve, providing insights into the possibility of life beyond Earth. "Earth-like planets in the ...
