NASA discovers 7 Earth-like planets orbiting a nearby star

For the first time ever, astronomers have discovered seven Earth-size planets orbiting a nearby star — and these new worlds could hold life.

This cluster of planets is less than 40 light-years away in the constellation Aquarius, according to NASA and the Belgian-led research team who announced the discovery on Wednesday.

The planets circle tightly around a dim dwarf star called Trappist-1, barely the size of Jupiter. Three are in the so-called habitable zone, where liquid water and, possibly life, might exist. The others are right on the doorstep.

Scientists said they need to study the atmospheres before determining whether these rocky, terrestrial planets could support some sort of life.

But it already shows just how many Earth-size planets could be out there — especially in a star’s sweet spot, ripe for extraterrestrial life.
