A telescope searching for interplanetary systems has detected a large gap in the dust disk around a young star, which could indicate the presence of multiple planets. The star is similar in size to our own Sun. Studying early-stage extrasolar planets and their host stars helps scientists to understand the formation of solar systems—including our own.
