what a discovery !!
NASA announces
Astronomers have discovered not one, not two, but seven Earth-sized planets orbiting a star called TRAPPIST-1.
What’s more, three of them are in the habitable zone— the happy place where liquid water can exist on the surface of rocky planets, as it’s not too hot or cold. (Although liquid water could potentially exist on any of the seven, NASA said, it likes the odds on those three best.) The space agency calls the discovery of the fascinating solar system record-breaking.
