This is an artist's rendition of the one-million-year-old star system called UX Tau A, located approximately 450 light-years away.
Observations from NASA's Spitzer Space Telescope showed a gap in the dusty planet-forming disk swirling around the system's central sun-like star. In our solar system, this gap would roughly extend between Mercury and Pluto. Astronomers suspect that the gap was carved out by one or more forming planets.
