This 4:37 video explains who astronomers have discovered the most Earth-like planet outside our Solar System to date. It is an exoplanet with a radius only 50% larger than the Earth and capable of having liquid water. Using the ESO 3.6-m telescope,a ...team of Swiss, French and Portuguese scientists discovered a super-Earth about 5 times the mass of the Earth that orbits a red dwarf,already known to harbor a Neptune-mass planet. The astronomers have also strong evidence for the presence of a third planet with a mass about 8 Earth masses. A good video to show students what astronomers do and to expand their interest in space exploration.

Scientists are on the verge of answering one of the greatest questions in history: Are we alone? Combining the latest telescope images with dazzling CGI, "Finding Life Beyond Earth" immerses audiences in the sights and sounds of alien worlds, while t...op astrobiologists explain how these places are changing how we think about the potential for life in our solar system. We used to think our neighboring planets and moons were fairly boring — mostly cold, dead rocks where life could never take hold. Today, however, the solar system looks wilder than we ever imagined.

"The search for Earth-like planets is reaching a fever-pitch. Does the evidence so far help shed light on the ancient question: Is the galaxy filled with life, or is Earth just a beautiful, lonely aberration? If things dont work out on this planet or... if our itch to explore becomes unbearable at some point in the future, astronomers have recently found out what kind of galactic real estate might be available to us. We'll have to develop advanced transport to land there, 20 light years away. The question right now: is it worth the trip?' This video has English captions. (21:29)
