Ultima Thule: The spatial snow-shaped rock is actually flat as a pancake | science



The remote cosmic snowman, visited by NASA last month, has a surprisingly flat, not a circle behind his back. The two-sided object, called Ultima Thule, is actually lighter than the back side than initially thought by scientists.

Photographs released late last week – taken shortly after the closest New Year's Day – give outline of not illuminated by the sun.

When viewed from the front, Ultima Thule still resembles a two-ball snowball. But on the part of a snowman he seems crushed, something like lemon and pie, glued together, to the end.

"Seeing more data significantly changed our vision," said Alan Stern of the Southwest Research Institute. declaration. "It would be closer to reality than to say that the shape of Ultima Thule is flatter, like a pancake. But more importantly, the new images create scientific puzzles about how such an object can even be formed. We have never seen anything like orbit around the sun. "

John Weaver's John Weaver of Helve Wee, home of the New Horizons Flight Management Center, said this discovery should spark new theories about how these primitive objects are formed at the start of solar energy

Ultima Thule – considered a contact couple – is the farthest world that has ever been studied. The new horizons have gone past him at high speed as they have become Pluto's first visitor in 2015. Mission leaders hope to move to an even farther celestial object in this so-called Kuiter belt, the frozen fringes of the Solar system if the spaceship remains healthy.

New Horizons is now 52 miles away from Ultima Thule. It will take another year and a half to broadcast all the flight data.
