New Horizons' Next Target May Resemble Rosetta's Comet 67P Or Be A Binary Pair

One artist’s concept of Kuiper Belt object 2014 MU69, the next flyby target for NASA’s New Horizons mission. This binary concept is based on telescope observations made at Patagonia, Argentina on July 17, 2017 when MU69 passed in front of a star. New Horizons theorize that it could be a single body with a […]

Moons are exceedingly common in the Solar System – Jupiter alone has 67! But smaller planets do as well of course, except for Mercury and Venus, and even some […]

New Horizons Reaches Halfway Point Between Pluto and Next KBO Target

New Horizons is now halfway from Pluto to its next destination – the KBO known as 2014 MU69, which it will reach on Jan. 1, 2019 (artist’s conception). Image Credit: NASA/JHUAPL/SwRI

It may not seem like it, but it is approaching two years now since New Horizons made its historic flyby of Pluto and […]

So-called “waterworlds” have been found to be surprisingly common in the Solar System—small icy moons which have ice crusts but oceans of liquid water below the surface. These include Jupiter’s moons Europa […]

New Horizons Obtains New Images and Science Data of Post-Pluto Kuiper Belt Object
