This is Ultima Thule, the farthest heavenly body reached by humans

The NASA space probe, which gave the world the first pictures close to Pluto, it New Horizon, reached the farthest celestial body ever explored by humans: An object covered in ice in the Kuiper Belt called "Ultima Thule" and located 6,400 million kilometers from Earth. Never had the human eye reached so far in the universe.

It was January 1 at 0:33, The time of America, when New Horizon went to "scarce" 3,500 km of Ultima Thule and began observing the mysterious celestial object through its powerful goals. In black and white and in low resolution, the first images sent by the probe show a celestial body in the middle and two protrusions shaped like a bowling pin.

After being out of touch for 10 hours, mission control personnel at Johns Hopkins University in Maryland were outlawed in applause after receiving confirmation signals from the probe, which could have been severely damaged during his long journey.

Ultima Thule seems to have a reddish color like brick. Scientists say there are no impact craters in the new images. Scientist Jeff Moore said the two balls formed when small fragments joined the space billions of years ago. Then the two balls came spirally together and melted together.

"We have a healthy spacecraft. We have completed the farthest flight ever made by Humanity"Alice Brown, operations manager for probe emissions, said." We are ready for Ultima Thule's scientific transmissions to help us understand the origins of our solar system, "he added.

"We've reached a record," says project manager Alan Stern of the Southwest Research Institute.. "A special vehicle has never explored anything so distant from us," he said. "Think we are a billion miles (1,600 million miles) longer than Pluto." Ultima Thule, wrote Stern in New York Times, "is 17,000 times farther from Apollo's moon mission" the great step ".

For the new horizons, it is another historic mission: In 2015, the ship flew over Pluto took an extraordinary series of images of the surface of the planet. The pictures revealed that Pluto is a world where nitrogen mountains rise from the ground and volcanic eruptions emit the ice into a small hydrocarbon content.
