Scientists found a new place to look for aliens.
Belgian astronomers just discovered three planets, that are about the size of Earth, orbiting a star 40-light years away.
The planets are close enough to look for signs of life.
NASA is already using its Spitzer space telescope to do that.
They’ll use the Hubble telescope next week.
Astronomers speculate that one of the planets is located far enough to have water and, possibly life.
“Systems around these tiny stars are the only places where we can detect life on an Earth-sized exoplanet with our current technology,” study author Michael Gillon said in a statement. “So if we want to find life elsewhere in the universe, this is where we should start to look.”
