Universe is Full of Exoplanets

30 years ago, astronomers confirmed the first planets, outside our Solar System. These 2 extrasolar planets, were orbiting a star 2,300 light-years away. Since then, NASA has documented over 5,000 more exoplanets, with unique characteristics, just waiting to be explored. Dozens of those, could even be habitable. Better telescopes will continue to reveal more.
