The most detailed image of Ultima Thule, returned from New Horizons reveals surface details ] including pits on the two vanes of the object and the contrast patterns of darkness and light in different regions. A part of the spacecraft The Ralph tool The last image, sent on January 18-19, has a large- a resolution of 440 feet (135 meters) per pixel. It was done at 12:26 am on January 1, just seven minutes before the closest approach, from a distance of 4,200 miles (6700 kilometers).

Mission scientists improved the image in a process known as deconvolution to bring out details of Ultima Thule's surface. Close to the object terminator, the line separating the day and the night side, there are many small pits with a diameter of 0.7 km. These can either be shock craters or collapse results caused by the release of organic molecules in the earliest days of CBC.

The contrasting areas of darkness and light are present in both Ultima's blades, the brightest being the door that holds them. together. While the reason for these models remains unknown, scientists believe they can provide information about the origins of Ultima Thule and about the merger of its two lobes.

On a smaller lobe, a circular characteristic that looks like a crater with a diameter of approximately four

"This new image begins to reveal the geological differences between the two Ultima Thule shovels and also introduces new mysteries. In the next month there will be better colors and better dividing images that hope to help uncover the many mysteries of Ultima Thule, "Mission Chief Researcher Alan Stern of Southeastern Research Institute SwRI ) in Boulder, Colorado, said Since New Horizons is about 4.13 billion miles (6.64 billion kilometers) from Earth, signals that travel at universal light speed take six hour and nine minute way. The return of all data collected during the New Year's Flight will take a total of 20 months.
