Alien Oceans

The bright glint of alien oceans may be visible from afar, allowing astronomers to flag potentially habitable exoplanets. As Earth travels around the sun, it moves through phases much like the moon when seen from afar. The planet's oceans reflect a great deal of light, especially during the crescent phase. The same principle should apply to exoplanets, researchers say. Seeing excessive brightness at the crescent phases could be a telltale signal of ocean planets.
