Since it’s always nice to make new friends, NASA is on the lookout for exoplanets. These are planets outside our solar system. They orbit a faraway star or float freely between stars.
We’re especially curious about planets similar to Earth. In our vast universe, with countless galaxies, stars, and planets, are there other planets like our own? Do they have living things we could never imagine? Are there other intelligent living things that are looking for us as we are looking for them?
We don’t know! But we’d sure like to find out.
