During the press conference held by the US National Aeronautics and Space Administration today, they announced the newly discovered Earth-sized planets orbiting a single star in the Trappist-1 system.

According to NASA, three of the seven Earth-sized planets are found within the star's habitable zone, so that means liquid water and life could exist on those planets' surfaces.

Unfortunately, humans won't be able to travel there anytime soon. In a cosmological sense, the star system is located nearby, but it's still about 40 light years away from Earth.

The planets were discovered with an infared telescope launched in 2003, the Spitzer Space Telescope. NASA said that they'll have more accurate measurements of the mass of the seven planets next year.

So what do you think about this amazing discovery? Do you think NASA will soon discover alien life in these planets?
