Close-up observations of the near-Earth asteroid Bennu have revealed many surprises, NASA announced today […]

New Horizons' Data of Pluto/Charon Show Rarity of Small Kuiper Belt Objects

Saturn’s rings are one of the most beautiful and breathtaking sights in the Solar System – but it hasn’t always been that way. New evidence in data sent back by the now-defunct Cassini spacecraft shows that they […]

New Horizons' Historic Flyby of Ultima Thule Reveals 'Entirely New Kind of World'

The first detailed image of Ultima Thule, showing two rounded lobes with a bright “neck” connecting them. It was taken at 5:01 Universal Time on Jan. 1, 2019, just 30 minutes before closest approach from a range of 18,000 miles (28,000 kilometers), with an original scale of 730 feet (140 meters) per pixel. Image […]
