    , now in stereo! The science team created the first stereo image pair of Ultima Thule. This image can be viewed with stereo (3D) glasses to reveal the unique Kuiper Belt object's three-dimensional shape.

    Zoom with a view: Made from two images taken 38 minutes apart, here is ! The "Thule" lobe is closest to the spacecraft. As Ultima Thule is seen to rotate, hints of the topography can be perceived.

    More science incoming! Yesterday we learned that is made of 2 separate objects that are now bound together. What will we learn today? Join experts at 2pm ET for the latest science sent to Earth from ~1 billion miles past Pluto

    On New Year’s Day, flew past – the most distant object ever explored. While the flyby was quick, it'll take ~20 months to downlink the full data set from the spacecraft, which is more than ~4 billion miles from the Sun:

    It's been a big week for small objects in the solar system. A billion miles past Pluto, explored a small Kuiper Belt object for the first time, while closer to Earth, entered orbit around an asteroid. See details at

    Sorry for the confusion! is not the first contact binary explored by a spacecraft – ’s Rosetta mission explored a comet of this shape. Ultima is however, the first contact binary in the Kuiper Belt ever explored up-close. Learn more:
