NASA's Kepler project last month discovered the first planet from another star that could possibly hold liquid water on its surface. So far, the Kepler Program has found more than 1,000 planets.
Using European Space Agency's Herschel Space Observatory, astronomers have discovered a disc of water vapor orbiting around a planet outside our solar system. The scientists say that there's more than enough cold water vapor to fill the oceans on Earth and suggested this could be how they formed. They also theorize that comets that are formed within the disc could be responsible for transporting water to other parts of the solar system.
Scientists using the 10-meter Keck telescopes in Kamuela, HI have captured evidence of a planet forming around a star. Scientists say that LkCa 15 b is the youngest planet ever found.
