Interstellar
Itsy Bitsy Solar System:
This artist's conception compares a hypothetical solar system centered around a tiny "sun" (top) to a known solar system centered around a star, called 55 Cancri, which is about the same size as our Sun. Astronomers using a combination of ground-based and orbiting telescopes, including NASA's Spitzer Space Telescope and the Hubble Space Telescope, discovered the beginnings of such a miniature solar system 500 light-years away in the Chamaeleon constellation.
