The search for life beyond Earth is really just getting started, but science has an encouraging early answer: there are plenty of planets in the galaxy, many with similarities to our own. But what we don’t know fills volumes.

Observations from the ground and from space have confirmed thousands of planets beyond our solar system. Our galaxy likely holds trillions. But so far, we have no evidence of life beyond Earth. Is life in the cosmos easily begun, and commonplace? Or is it incredibly rare?

Answer 2

Step-by-step explanation:

Standing under a starry sky and gazing up at its wonder, it's easy to believe that we're alone in the cosmos. The distances are vast, and, after all, we know of only one planet in the universe that hosts life — ours. But it's possible we may not be alone even in our own solar system.
