Astronomers have found three planets orbiting far-off stars that are close to Earth-sized and in the "habitable zone": a distance from their suns that makes the planets' surfaces neither too hot nor too cold, but just right.
One of the three planets orbits a star with the prosaic name Kepler-69.

Scientists have unraveled the genome of the coelacanth, a rare and primitive fish once thought to be extinct, shedding light on how closely it's related to the first creatures to emerge from the sea.
The coelacanth, a fish that can reach up to 5 feet long and lives in deep ocean caves, had only been seen in fossils and was thought to have gone extinct some 70 million years ago. That was until 1938, when fishermen from the Comoros islands off the coast of Africa captured one in a net. A second coelacanth species was discovered off the Indonesian island of Sulewesi in 1997.
