The Milky Way is teeming with billions of planets, including many that are similar to our own. But how many of these alien worlds have water, and do any host extraterrestrial life?
No answers to those questions just yet. But astronomers using a new infrared technique say they’ve discovered water vapor in the atmosphere of a nearby gas giant planet called “tau Boötis b.”
The finding suggests that the technique may play an important role in identifying which exoplanets might be hospitable for life.

While astronomers didn’t bag that elusive first “alien Earth” in 2013, they made plenty of exciting exoplanet discoveries during the past year.
Here’s a list of the top exoplanet finds of 2013, from a tiny world about the size of Earth’s moon to a blue gas giant on which it rains molten glass:
The smallest exoplanet
In February, astronomers announced the discovery of Kepler-37b, the smallest alien world ever found around a sun-like star. The planet is about 2,400 miles (3,900 kilometers) wide, making it just slightly larger than Earth’s moon.
