NASA's new telescopes could spot alien life within 20 years
Convinced that there's got to be life on other planets? You're not alone in the universe -- in fact, many NASA scientists agree with you.

Recent projects, like the Kepler Telescope, Dark Energy Survey and the Very Large Telescope have detected the presence of planets and even their atmospheres. But astronomers are even more excited about future projects like the Transiting Exoplanet Surveying Satellite (TESS) and James Webb Space Telescope, set to launch in 2017 and 2018, respectively.
