NASA's New Horizons Spacecraft Sends Back First Images of Ultima Thule, Looks Like a 'Snowman'

The first detailed images beamed back from the US bureau’s New Horizons mission enabled scientists to confidently determine the body has been formed when two spheres, or”lobes,” slowly gravitated towards each other till they stuck together – a major scientific discovery.

The New Horizons spacecraft on Tuesday flew beyond Ultima Thule, which was discovered via telescope at 2014 and is the farthest and possibly oldest cosmic body ever observed by means of a spacecraft.

Before that flyby, the only image scientists needed was a fuzzy one revealing Ultima Thule’s oblong shape, resembling something like a bowling pin or a peanut butter.

“This image is so 2018… Meet Ultima Thule!”

“That bowling pin is gone – it is a snowman if anything in any way,” Stern said through a NASA briefing.

“This spacecraft and this group accomplished is unprecedented.”

Ultima Thule’s surface reflects light about as far as”garden variety grime,” he stated, since the sun’s rays are 1,600 times fainter there than on Earth.

The body is roughly 19 miles long and completes its own rotation in about 15 hours. NASA dubbed the larger lobe Ultima, and the other, which is roughly three times smaller, Thule.

“This is the very first object which we can certainly tell was born this way” Stern explained, rather than evolving as a type of”bi-lobe.”

We are aware this is how these kinds of objects in many cases form.”

‘A time machine’

Some 4.5 billion years ago a cloud of suspended pebbles began to join forces, gradually forming two bodies – Ultima and Thule.

Slowing turning, they finally touched each other at what assignment geology supervisor Jeff Moore called an”extremely slow speed” – perhaps one to a few miles per hour.

If such a meeting occurred between two cars in a parking lot, he said, no driver would bother writing this up. The lobes, according to Moore, are just”resting on each other”

“New Horizons is similar to a time machine, taking us back to the arrival of the solar system,” Moore stated. “We are seeing a physical representation of this beginning of planetary formation, frozen in time”

Carly Howett, another researcher of the mission, noted that”we can definitely say that Ultima Thule is red,” possibly because of irradiation of ice.

NASA researchers promised new statements would drop Thursday, including on the composition and air of Ultima Thule, as new graphics with even more precise resolution have come through.
