Microlensing Reveals Sub-Saturn Giant Planets are Common, Not Rare

Astronomers have found a new exoplanet that could alter the standing theory of planet formation. With a mass that's between that of Neptune and Saturn, and its location beyond the "snow line" of its host star, an alien world of this scale was supposed to be rare.

Hit-and-Run Heist of Water by Terrestrial Planets in the Early Solar System

A study simulating the final stages of terrestrial planet formation shows that 'hit-and-run' encounters play a significant role in the acquisition of water by large protoplanets, like those that grew into Mars and Earth.

NASA Urged To Mount Large Direct Imaging Mission For Exoplanets

To answer significant questions about planetary systems, such as whether our solar system is a rare phenomenon or if life exists on planets other than Earth, NASA should lead a large direct imaging mission - an advanced space telescope.

A New Stage In The Evolution of Young Solar Systems

Astronomers from the Department of Physics at the University of Tokyo discovered a dense disk of material around a young star, which may be a precursor to a planetary system.

Astronomers Find A Famous Exoplanet's Doppelganger

When it comes to extrasolar planets, appearances can be deceiving. Astronomers have imaged a new planet, and it appears nearly identical to one of the best studied gas-giant planets.
