Astronomers Discover a Young Solar System Around a Nearby Star

| Science

An international team led by Thayne Currie of the Subaru Telescope and using the Gemini South telescope, has discovered a young planetary system that shares remarkable similarities to our own early solar system. Their images reveal a ring-line disk of debris surrounding a Sun-line star, in a birth environment similar to the Sun’s. The disk appears to be sculpted by at least one unseen solar system-like planet, is roughly the same size as our solar system’s Kuiper Belt, and may contain dust and icy particles. This work provides a valuable key to understanding the early formation of the Sun and planets.
