Space News of the Day: Three Exoplanets May Be Life-Sustainable
After four years circling space looking for new planets, the Kepler spacecraft has identified three planets that look like they could possibly sustain life. The first two, known as Kepler-62e and Kepler-62f (shown above, top and middle), are approximately 1,200 light-years away and have estimated temperatures of -3 degrees C (26.6 F) and -65 degrees C (-85 F) respectively. The third planet, Kepler-69c (shown above, bottom) boasts a summer day-like temperature of 27 degrees C (80.6 F). Some scientists think these planets could actually be covered in oceans, but they are unsure if they would be composed of water or some other liquid.
