By untangling the forces that shape these distant worlds, we inch closer to answering some of humanity’s oldest questions: How common are planets like Earth? Is there other life among the stars?

Astronomers have discovered that sulfur may be a key to helping us narrow down our search for life on other planets. It's not that sulfur is a great indication that a planet is inhabited.
