"Discovery of Mysterious Celestial Bodies Challenges Solar System's Understanding"

Scientists have discovered evidence of large objects beyond the outermost perimeter of the Kuiper Belt, suggesting that the belt is deeper than previously thought. The objects, detected by NASA's New Horizons spacecraft, could be located beyond 60 astronomical units (AU) from the solar system's center, indicating the possibility of a second belt. However, the findings are preliminary and further research is needed to confirm their existence. Telescopes have yet to detect objects beyond the Kuiper Belt's limits, but dimming in stars observed by the Hubble Space Telescope suggests the presence of undiscovered Kuiper Belt objects.
