The New Horizon assembly reveals that Ultima Tule has a dual identity

This image, available from NASA on January 2, 2019, shows pictures with special colors and detailed information, as well as an intricate picture of both, showing Ultima Thule, about 1 billion miles away from Pluto.

Scientists have the first good look at the remote object of the solar system called Ultima Thule and realized they are seeing double. Ultima Thule appears as a pair of rounded bodies gently pushing together to remind a flying interplanetary snowman.

Images unearthed by NASA's New Horizons investigation on Tuesday and released on Wednesday show that most of the spherical components that make up the Ultima Thule are about three times larger than the smaller one.

"It can be seen that there are clearly two separate items that were gathered," said Kathy Olkin, project scientist at a briefing for a journalist at John Hopkins Laboratory in Laurel, MA. "This form informs our models of planetary forms ".

The new look suggests that Ultima Thule is everything that scientists hope – a detailed picture of a process that has ever led to the birth of planets, in which small bodies called planesize are aggregates to build larger ones.

With data that continues to be released from the spacecraft on Wednesday, team members said they expected the results to significantly improve their understanding of how the solar system originated.

The new horizons left the Earth nearly 13 years ago and became the first spacecraft to provide Pluto images in 2015. Then, it was three and a half years old until Ultima Thule, located 1.5 billion kilometers above Pluto's orbit in a region known as the Kuiper Belt.

Traveling to more than 51,000 kilometers per hour, New Horizons bypassed Ultima Tule early in the morning with cameras and instruments, which captured what it found there. Ten hours later, raw data from the mine meeting began to arrive via a radio link from the rapid melting of the spacecraft, and team members spent the next 24 hours merging images and debating about the implications of what they watched.

Even now, with only 1 percent of meeting data that is already in hand and the best images to be brought, scientists say they are convinced that Ultima Thule changed little after spewing dust and gas around him baby about 4.5 billion years ago.

"We think that what we see is perhaps the most primitive object that has not yet been detected by any spacecraft," said Timothy Moore, a member of the NASA research team at the Hayes Research Center in California.

Dr Moore noticed that the shape of Ultima Thule supports the formation of a planet in which small pieces ranging from stones to stones are accumulated to form spherical objects about 10 kilometers. The two Ultima Thule pieces coincide with this description and both look a little underlined – a possible hint that each one is composed of smaller pieces merged together.

The color image shows that the object is reddish, indicating that its surface contains carbon-containing molecules such as methane and carbon monoxide in frozen form. After billions of years of exposure to cosmic radiation, such a surface will usually become reddish-brown because carbon atoms react chemically and connect to longer tar compounds.

Equally striking is the apparent lack of craters, as a result of a study published last week, suggesting Kuiperi's belt is relatively free from small parts of debris that thoroughly destroyed many asteroids and moons that are closer to the Sun. And since it is thought that the objects in the region are moving at a slow speed relative to each other, even those craters that are formed are expected to look like ordinary homes.

Brett Gladman, an astronomer at the University of British Columbia and co-author of the study on the crater, says that as sharper images of the spacecraft are taken, several of the brightest parts appearing in news images can turn into shallow craters made of objects that they moved slowly enough to survive falling into Ultima Thule.

"I'll be very curious to see if they are stones that basically sit in various," said Dr. Gladman.

JJ Kavelaars, an astronomer with the Canadian National Research Council, who was involved in the search for the Kuiper Belt Belt for new visiting horizons and is a member of the mission's scientific team, said the experience of seeing images coming this week is almost unknown.

"It's sitting there in space for four and a half billion years, and now people have managed to get out and see it … … I have the awe of this accomplishment," he said.
