GAIA Spacecraft Could Find 70,000 Alien Planets

Share

The European Space Agency’s Gaia spacecraft could potentially find 70,000 alien planets if it keeps operating for 10 years. Launched in December 2013, it will identify a minimum of 21,000 exoplanets, even more if things go well.
Gaia will also provide specific details about the planets it discovers, such as size, structure, orbit, composition of atmosphere and more. We’ve gone a long way since the first discovery of an exoplanet in 1995.
Looks like a lot of answers are right around the corner!
