A new image captured minutes before NASA’s New Horizons probe zipped by a rocky object in the Kuiper Belt on New Year’s Day shows the dual-lobed world — nicknamed Ultima Thule — is covered with intriguing fractures and a large crater-like depression that could provide clues about the early history of the solar system.

The first well-resolved image of the faraway chunk of rock fleetingly visited by NASA’s New Horizons spacecraft on New Year’s Day reveals the object — officially named 2014 MU69 but nicknamed Ultima Thule — is made of two lobes scientists say came together in an ancient slow-speed collision just as the solar system’s planets were forming.

A fresh image from NASA’s New Horizons spacecraft released Tuesday showed the mission’s distant flyby target a billion miles beyond Pluto — nicknamed Ultima Thule — has an elongated shape like that of a peanut shell or a bowling pin, and the prospect of higher-resolution pictures arriving on Earth later in the day had scientists salivating for more.

New Horizons phones home, confirms successful flyby

January 1, 2019 William Harwood

NASA’s New Horizons spacecraft raced past a frozen remnant of the solar system’s birth early New Year’s Day, phoned home to confirm a successful flyby and readied a treasure trove of pictures and other data for transmission back to eager scientists some 4.1 billion miles away.
