The Carl Sagan Institute is a special building where really smart people work together to study outer space and everything in it. The people who work there are called scientists and astronomers. They use big telescopes and fancy machines to look far into space and learn more about planets, stars, and galaxies. They want to know if it's possible for other creatures to live on other planets besides Earth. Carl Sagan was a really smart and famous scientist who thought a lot about space and the possibility of life on other planets. This institute is named after him to honor his work and inspire others to keep studying the wonders of the universe.
