NASA's space attack probe, which travels 640 million kilometers from Earth on Wednesday, sent its first images of the closest space object that has been researched, showing a reddish snowdrop.
It has been established that Ultima Thule, as a small frozen object is baptized, consists of two united spheres, one of them three times larger than others, and extends about 33 kilometers.
The new horizons, the investigation that Pluto had sent photos three and a half years ago, went from a mysterious object in the early hours of the New Year. It is 1,600 million kilometers away from Pluto.
Based on the first and vague pictures taken the previous day, scientists say that Ultima Thule resembled a prick pin. However, when sharper images are sharper, a new consensus emerged.
"The bowling alley has disappeared, it's a snowman!" Said Alan Stern, a leading scientist, from the Applied Physics Laboratory at Johns Hopkins University, where he controls the mission in the city of Laurel. The picture of the bolus is "tan del 2018", joked Stern, who works at the Southwest Research Institute.
The celestial body was called Ultima Thule _ which means "outside the familiar world", before scientists could say with certainty whether it is an object or two. With the advent of photos, they now call "Ultima" the biggest sphere and the smallest "Thule".
The brick is estimated to be 14 kilometers (nine miles) in diameter, while Ultima is believed to have a width of 19 kilometers (12 miles).
Scientists Geoff Moore of NASA's research center, Ames, said the two spheres were formed when small, frozen fragments were merged in billions of years before the universe. Then the two spheres approached slowly and spiraled until they touched gently and fused "firmly".
Ultima Thule appears to have a reddish-colored brick, probably due to the effects of radiation that bombards the ice sheet. Scientists say there are no craters for the impact of new photos.
