NASA's New Horizons Reaches a Rare Space Milestone

NASA's New Horizons spacecraft has achieved a significant milestone, becoming one of the few spacecraft to travel over 50 astronomical units (AU) from the Sun. An astronomical unit is the average distance between the Earth and the Sun, approximately 93 million miles. Launched in 2006, New Horizons is best known for its historic flyby of Pluto in 2015, providing the first close-up images and data about the dwarf planet. The spacecraft continues to explore the outer reaches of the solar system, sending back valuable data and insights that help scientists better understand the formation and evolution of our cosmic neighborhood.
