Meet #UltimaThule! What you’re seeing is the 1st contact binary ever explored by a spacecraft. This object, which we can now see is a contact binary, used to be 2 separate objects that are now bound together.

THIS is #UltimaThule.

The image taken by @NASANewHorizons – shown in its original version (left) & sharpened version (on right) – is the most detailed image of the farthest object ever explored by a spacecraft. https://t.co/gItPsMvbPC @NASA pic.twitter.com/i7rDBURNrw

It's official! I'm in orbit around #asteroid Bennu — now the smallest body ever orbited by a spacecraft. My snug path around the asteroid also sets a new record for the closest orbit of a planetary body by any spacecraft. #HappyNewYear, indeed! More ➡️ https://t.co/fwL3FEVU9m pic.twitter.com/ceavR7ju6i

Absolutely beautiful video created using still images taken by the Cassini spacecraft during its flyby of Jupiter and while at Saturn. Shown is Io and Europa over Jupiter's Great Red Spot and then Titan as it passes over Saturn and it's edge-on rings. NASA/JPL/Kevin M. Gill pic.twitter.com/BWaVP5h6Ob

We got images!!

This is what 2014 MU69 #UltimaThule looks like: Anybody wanna peanut?

… but it still might be two separate objects in orbit. We’ll know better tomorrow. pic.twitter.com/EVYbmcXNoO
