The primordial solar nebula was much larger than previously thought, and this may have implications for studying the planet formation process in our Solar System.
The researchers discovered a cluster of 11 objects orbiting in a ring at a heliocentric distance between 70 to 90 AU, separated from the belt by a large, empty gap.
If this is confirmed, it would be a major discovery, suggesting that there could be an entire structure of objects lying beyond the uncharted darkness of the Kuiper Belt.
These latest observational efforts were intended to assist New Horizons, and in so doing, have picked up something even further than the belt.
