Cosmic snowman revealed, now in 3-D

LAUREL, Md. — The science team behind NASA’s New Horizons spacecraft today released the first 3-D image of an icy object more than 4 billion miles from Earth, and the variations in the picture hint at ridges, craters and knobby features that will be more fully charted as the resolution improves.

Two pictures, separated by just a moment in time, were fused together to produce a somewhat fuzzy but depth-enabled glimpse at the object — which has the official designation of 2014 MU69 but has been nicknamed Ultima Thule by the New Horizon team.

“Features appear to be rotating into view as the object twists underneath us,” Paul Schenk, a New Horizons co-investigator from the Lunar and Planetary Institute, said during today’s briefing here at Johns Hopkins University’s Applied Physics Laboratory. “These have a knobby appearance, and could be the inside of a large impact crater that’s on the far side.”

The stereo view also appears to highlight ridge structures on the 19-mile-long object, which has been compared in appearance to a snowman or the BB-8 droid from “Star Wars.” Some of the ridges could represent elevation variations amounting to several hundred feet, he said.

Schenk said a side-by-side version of the 3-D images was created by Brian May, an astrophysicist specializing in scientific stereoscopy who also happens to be the lead guitarist for the classic rock group Queen.
