In 2014, it was assumed that MU69 originally had two nicknames named & # 39; ; Ultima & # 39; and "Thule", which has evolved over time from a rotating cloud of small, icy bodies.A comparison with known cometary cores suggests that Ultima Thule becomes a typical comet when entering the inner NASA / JHUAPL / SwRI [19659006] When 2018 ended and 2019 began, NASA's New Horizons flew past Pluto past its first destination: 2014 MU 69 .

Ultima Thule is scarcely a picture (left) of the spaceship New Horizons The distant world stands out more when the stars are removed (right), the dark spots are artefacts from the incomplete star subtraction, yellow crosshairs marks the position of Ultima In recent days, MU69 (Ultima Thule) was only in effect in 2014 as a pixel in the detectors of New Horizons. NASA / JHUAPL / SwRI [19659006] Nicknamed Ultima Thule transforms from a single pixel in our detectors into a red-tinged, spotty snowman.

The first three weeks of the data have revealed spectacular details about this distant world.

Several images of Ultima Thule (2014 MU69), as New Horizons approached, reveal a rotating and tumbling body, but show additional details about the object as the distance from the camera has been reduced from 500,000 to 28,000 km: a decline 94 NASA / JHUAPL

Apart from its inactivity, it perfectly fits our expectations of cometary cores.

Many comets have their cores imaged by different spacecraft, with two main classes of cometary cores becoming visible: a single object nucleus and a contact binary core in 2014, MU69 appears to be of the binary contact type and marks the first time we image such an object before it ever develops a tail or loses some of its volatiles.

In 1986, the Halley Comet was imaged by ESA's Giotto mission, revealing a bilobed core.

Similarly, Deep Impact's photographs of comet Hartley 2 from 2010 showed volatilely laden lobes connected by a smooth neck.

NASA's Deep Impact Probe captured these images of comet Hartley 2, revealing the outgassing at the edges of one of its lobes and large differences in surface reflectivity from region to region. The smooth neck is probably not a flaw, but a feature common to many contact bears originating from the Kuiper belt, as the accumulation of icy material leads to this configuration. Scientists are still collecting data from the New Horizons flyby of 2014 MU69, which could shed more light on the details of the glacial formation. NASA / JPL / UMD

ESA's Rosetta mission, however, set a new standard in Cometary Imaging.

A high-resolution image of Comet 67P / Churyumov-Gerasimenko reveals a large body consisting of two lobes connected by a thinner neck. Similar to Halley's Comet or 2014 MU69, the comet Hartley 2 shows a "contact binary" configuration. We now believe that this is customary for objects of the Kuiper Belt. ESA / Rosetta / NAVCAM

His now legendary snapshots and films of Comet 67P / Churyumov-Gerasimenko show degassing, feathers and even snow.

The Sun – The sides of the comets are first heated, with slightly sublimated amounts of ice leading to exhaust, release of pressure and loss of material. The longer comets spend near the sun, the faster they evaporate. For items still in the Kuiper Belt, evaporation should be negligible. ESA / Rosetta / NAVCAM

Volatile, icy materials are abundant on this comet and change rapidly when exposed to sunlight.

Ultima Thule is currently spinning and stumbling in a similar fashion to those known nearby comets.

This film shows the tumbling, propeller-like rotation of Ultima Thule over the span of nine hours between 20:00 UT (15:00 ET) on December 31, 2018 and 05:01 UT (01:01 ET) on the 1st. January 2019, as the Long Range Reconnaissance Imager (LORRI) on board shows New Horizons of NASA. NASA / JHUAPL

The only difference? It is still incredibly far from the sun, leaving its ice intact.

Based on the data so far from the New Horizons mission and their 2014 MU69 (Ultima Thule) images, we were able to do this Create a 3D model of what this object looks like. Its double-winged appearance with a smooth, reflective neck reveals a comet-like nature that is still completely frozen and never sufficiently volatile substances heated by the sun. Getty

Ultima Thule looks like a type of comet nucleus that represents the first image in its place of origin: the Kuiper Belt.

This NASA-provided image this Tuesday, January 1, 2019 shows the Kuiper belt object Ultima Thule, about 1 billion miles beyond Pluto, encountered by the New Horizons probe. The brightness differences correspond to differences in surface reflectivity. It will take about 20 months from the removal and trajectory of New Horizons to download all the data taken during the 2019 New Year's flyby. ASSOCIATED PRESS
