The first confirmation that planets exist beyond our solar system came in 1992, when a team of astronomers monitored changes in radio waves to prove that multiple planets were orbiting a small star about 1000 light-years away. Then, in 2005, astronomers created the first actual image of a planet beyond our solar system the date is arguable because the observation was made in 2004, but not confirmed until a year later. Since then, hundreds more planets have been discovered, and a few others have even been photographed.
