New Horizons Probe Successfully Flew by Ultima Thule, the Farthest Space Object Ever

Humanity sent a spacecraft to the farthest object ever explored, Ultima Thule, in the Kuiper Belt. The New Horizon Probe reached a record-setting space mission 4 billion miles away, a billion miles beyond Pluto.

This is the first exploration of a Kuiper Belt object up close. The flyby occurred at 12:33 a.m. ET on Tuesday, but the signal didn’t reach us until about 10:30 a.m. ET. The Kuiper Belt is the edge of our solar system

New Horizons sent back images of Ultima Thule — taken from half a million miles out.This is the best look scientists have ever had Ultima Thule. Before, they saw it as only a single pixel.

Ultima Thule, previously known as 2014 MU69, appears to have a bowling pin shape that’s spinning like a propeller. It’s could also be two objects orbiting each other. Higher resolution images should come streaming in all this week.

The New Horizons mission was launched by NASA in 2006 and took a nearly 10 year journey to conduct a flyby of Pluto in 2015, its mission was then extended in 2016 to visit the Kuiper Belt.
