We’re joining forces with our colleagues at Spaceflight Now to provide live coverage of the New Horizons spacecraft’s flyby of 2014 MU69 — also known as Ultima Thule — in the Kuiper Belt a billion miles beyond Pluto. Text updates will appear automatically below. Follow us on Twitter.
This image from NASA’s New Horizons spacecraft focuses on a section of the informally named Serenity Chasma, part of a vast equatorial belt of chasms on Pluto’s largest moon, Charon. Scientists believe that Charon’s subsurface water-ice layer may have been partially liquid in its early history, and has since refrozen, expanded and pushed the surface outward, producing the massive chasms we see today.
