NASA's Ultima Thule video reveals that "it does not look like any of the objects surveyed"



NASA's new horizonal probe has transmitted to Earth the most accurate images of Ultima Thule, considered to be the most remote and primitive space object ever to be studied, the US space agency reported.

These photos revealed the presence of odd patterns on the surface of the site – officially known as "2014 MU69", which scientists still can not explain.

It is located in the belt of Kaiper, approximately a distance from 6,640 million kilometers from EarthThat is why the radio signals – which travel through the space at the speed of light – arrive on our planet six hours and nine minutes late.

Historical recording with precision

In order to capture it, the mission's experts had to know at anytime the exact location of both the site and the probe, which on January 1 was only 3500 kilometers away from the target and at a speed of 51,500 kilometers per hour.

In this way, these images with a resolution of about 33 meters per pixel are obtained thanks to the highest precision of navigation throughout the history of space exploration, mission experts said.

This approach was "risky" given that "there was a good chance we could get only a part or even none of Ultima Thule" in the narrow field of view of the New Horizons camera, explained Alan Stern, the project's chief investigator. ,

Models that have never been studied

"Some of the details we now see on the surface of Ultima Thule do not look like any of the objects studied," Stern said, referring to stains. bright tone and round which are assessed on its surface.

Also, the new images reveal in more detail dark dents are present near the border between the sun-lit Last Thule zones and those that remain dark.

Scientists are convinced that high-resolution photography will determine the nature of these dents – which can be craters produced by effects of other organs or have arisen as a result of sublimation, collapse of the earth or another totally different phenomenon, as well as a study of the origin and evolution of 2014 MU69.
