Ultima Thule, probably the most distant house rock we’ve got ever visited, is continuous to confound astronomers. It has been variously described as a misshapen potato, a peanut, a bowling pin and a snowman. Now the newest footage taken by the New Horizons spacecraft on its flyby reveal one other twist.

The bigger bulbous finish of the rock, referred to as Ultima, just isn’t spherical as we had thought, however flat, like a cookie. The smaller bulb, referred to as Thule, can be considerably squashed, like a walnut.

“The brand new photos are creating scientific puzzles about how such an object might even be shaped,” mission scientist Alan Stern mentioned in an announcement. “We’ve by no means seen one thing like this orbiting the solar.”

NASA’s New Horizons hurtled previous Ultima Thule on New Yr’s Day this 12 months, taking footage and gathering knowledge because it flew inside 3500 kilometres of the 32-kilometre-long rock. The most recent footage have been taken after the spacecraft had handed it, revealing a unique angle.

Ultima Thule is regarded as a remnant of the early photo voltaic system, so finding out it might inform us about how the planets shaped. Its baffling form defies clarification for now, however is certain to encourage new theories as New Horizons sends again extra knowledge.
