Earth is the Only Planet Known to Have Life

Scientists have found historical evidence of organic molecules and water on Mars, as well as the basis for life on Saturn's moon Titan. Deep space nebulae can be seen to contain amino acids. Additionally, researchers have made assumptions regarding the potential for life to live below the ice surfaces of Titan and Europa, moons of Saturn. However, only Earth has really been found to have life.

However, scientists are developing experiments that will help find out if there is life in other worlds. The Nexus for Exoplanet System Science (NExSS), for instance, was newly established by NASA and will spend the ensuing years searching through the data returned by the Kepler satellite telescope (and other missions that have not yet been launched) for indications of life on extrasolar planets.

Massive radio dishes are now searching for the telltale signs of intelligent life stretching out across intergalactic space by examining distant stars. And more recent space observatories, including the James Webb Telescope from NASA, the Transiting Exoplanet Survey Satellite (TESS), and the Darwin project from the European Space Agency, may just have the power to detect the presence of life on distant planets.
