An international team of astronomers has discovered three Earth-sized exoplanets, all orbiting the same star just 40 light-years from us, the 16-nation intergovernmental research organization ESO reported on Monday.

The scientists have deemed all three planets potentially habitable, an exciting turn in the hunt for “exoplanets,” a term for planets that orbit a star other than our sun.

And it could bring us closer to finding extraterrestrial life.
