Scientists have discovered what looks like the best place where life (as we know it) may exist outside our own solar system.
Seven Earth-sized planets, all of which could contain water, have been found orbiting a small star 39 light-years away.
"We have made a crucial step toward finding if there is life out there," said Amaury Triaud, co-author of a study published Wednesday in the science journal Nature.
"I don't think any time before we had the right planets to discover and find out if there was.
"Here, if life managed to thrive … then we will know. Before, it was indication; now, we have the right target."
The discovery is the first of its kind. Never before have so many Earth-like planets been found orbiting a single star.
TRAPPIST-1 is 39 light-years away from Earth, or about 229 trillion miles (369 trillion kilometers). It would take 39 years to get to its current location traveling at the speed of light.
