This solar system of seven Earth-sized planets may be the best place to look for alien life Video Description

Around 40 light-years away, seven Earth-sized planets have been spotted orbiting closely around a small, ultra-cool star. It’s one of the largest solar systems that’s ever been discovered outside of our own, and it’s a particularly enticing find in the ongoing search for extraterrestrial life. Six of the planets in the system may have the right temperatures for liquid water to exist on their surfaces, and astronomers are confident they’ll be able to get a more in-depth look at these seven worlds with future space telescopes.
