Super-Earths can exist in wider orbits around their parent stars than was previously believed, suggesting these Earth-like ...

Dimethyl sulfide is cool—and a potential biosignature—but scientists are urging caution before we declare a plankton party ...

A distant flicker of light from a star can reveal more than you might expect. In fact, a brief, subtle brightening in the sky ...

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 ...

Since astronomers started discovering extrasolar planets, or "exoplanets," in the mid-1990s, worlds orbiting other stars have demonstrated that, compared to our somewhat mundane solar system ...

The findings in the study were made via microlensing, an observational effect that occurs when the presence of mass warps the ...

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.

Astronomers have spotted a small rocky planet that orbits perilously close to its host star disintegrating as its surface is ...
