NASA’s New Horizons Mission Releases Snowman-like Picture of Ultima Thule

Ultima Thule, an icy world 4 billion miles from the sun, looks like a big snowman.

At a news conference on Wednesday, scientists working with NASA’s New Horizons mission released several images that the spacecraft took as it flew by on Jan. 1.

The scientists now say with confidence that Ultima Thule long ago was two bodies that got stuck together, what they call a “contact binary.”

“Two completely separate objects that are now joined together,” said S. Alan Stern, the principal investigator for the mission.

...Planetary scientists have never before seen a close-up of an object like Ultima Thule. It is likely an icy fragment that coalesced more than 4.5 billion years ago and which has remained in a deep freeze of the solar system’s Kuiper belt ever since, some 4 billion miles from the sun.

“This is a night none of us are going to forget,” said Queen guitarist Brian May — who also holds an advanced degree in astrophysics — and who recorded a solo track to honor the spacecraft and its spirit of exploration.

Super cool...as both an expression and as a physical reality.

The "contact binary" concept is fascinating, two planetesimals that bumped into each other as the solar system was condensing out of ol' Sol's protoplanetary disk.
