File:Dust Models Paint Alien's View of Solar System.ogv

Summary

Dust in the Kuiper Belt, the cold-storage zone that includes Pluto, creates a faint infrared disk potentially visible to alien astronomers looking for planets around the sun. Neptune's gravitational imprint on the dust is detectable in new simulations of how this dust moves through the solar system. Though a similar thing that belongs to this would be the oort cloud. The simulations show how the distant view of the solar system might have changed over its history.
