January 2, 2019

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.

New Horizons scientists elated as Ultima Thule’s shape comes into view

January 1, 2019

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.

On eve of New Horizons flyby, Ultima Thule still holding onto its mysteries

December 30, 2018

A day before NASA’s New Horizons spacecraft closes in on a frozen outpost nicknamed Ultima Thule 4.1 billion miles from Earth, basic facts about the city-sized object continued to elude scientists Sunday as the ground team braced for a deluge of data and imagery that should unmask the unexplored world at the frontier of the solar system.
