И с какого хрена - оно такое тёмное?

Потому что камера настроена так, чтобы по максимуму использовать динамический диапазон. И снимки представлены так же.

Stern: almost exactly 3:1 ratio in size between the tow lobes. #UltimaFlyby

Stern notes the lighting geometry on approach makes it difficult to discern topography, like craters; as more images come in from other angles can better determine that. #UltimaFlyby

The following images will be even better, due to high resolution, better lighting and better presentation as New Horizon's passed by the object. Current image is 140 meters per pixel. 35 meters per pixel image is incoming.

Project scientists say they're looking forward in the next day or so for composition data and better topography, perhaps in time for tomorrow's briefing. #UltimaFlyby

NASA's New Horizons Mission Reveals Entirely New Kind of World
Images of the Kuiper Belt object Ultima Thule unveil the very first stages of solar system's history


This image taken by the Long-Range Reconnaissance Imager (LORRI) is the most detailed of Ultima Thule returned so far by the New Horizons spacecraft. It was taken at 5:01 Universal Time on January 1, 2019, just 30 minutes before closest approach from a range of 18,000 miles (28,000 kilometers), with an original scale of 730 feet (140 meters) per pixel.

Scientists from NASA's New Horizons mission released the first detailed images of the most distant object ever explored -- the Kuiper Belt object nicknamed Ultima Thule. Its remarkable appearance, unlike anything we've seen before, illuminates the processes that built the planets four and a half billion years ago.

"This flyby is a historic achievement," said New Horizons Principal Investigator Alan Stern of the Southwest Research Institute in Boulder, Colorado. "Never before has any spacecraft team tracked down such a small body at such high speed so far away in the abyss of space. New Horizons has set a new bar for state-of-the-art spacecraft navigation."

The new images -- taken from as close as 17,000 miles (27,000 kilometers) on approach -- revealed Ultima Thule as a "contact binary," consisting of two connected spheres. End to end, the world measures 19 miles (31 kilometers) in length. The team has dubbed the larger sphere "Ultima" (12 miles/19 kilometers across) and the smaller sphere "Thule" (9 miles/14 kilometers across).

The team says that the two spheres likely joined as early as 99 percent of the way back to the formation of the solar system, colliding no faster than two cars in a fender-bender.

"New Horizons is like a time machine, taking us back to the birth of the solar system. We are seeing a physical representation of the beginning of planetary formation, frozen in time," said Jeff Moore, New Horizons Geology and Geophysics team lead. "Studying Ultima Thule is helping us understand how planets form -- both those in our own solar system and those orbiting other stars in our galaxy."

Data from the New Year's Day flyby will continue to arrive over the next weeks and months, with much higher resolution images yet to come.

"In the coming months, New Horizons will transmit dozens of data sets to Earth, and we'll write new chapters in the story of Ultima Thule -- and the solar system," said Helene Winters, New Horizons Project Manager.

The Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, designed, built and operates the New Horizons spacecraft, and manages the mission for NASA's Science Mission Directorate. The Southwest Research Institute, based in San Antonio, leads the science team, payload operations and encounter science planning. New Horizons is part of the New Frontiers Program managed by NASA's Marshall Space Flight Center in Huntsville, Alabama.


The first color image of Ultima Thule, taken at a distance of 85,000 miles (137,000 kilometers) at 4:08 Universal Time on January 1, 2019, highlights its reddish surface. At left is an enhanced color image taken by the Multispectral Visible Imaging Camera (MVIC), produced by combining the near infrared, red and blue channels. The center image taken by the Long-Range Reconnaissance Imager (LORRI) has a higher spatial resolution than MVIC by approximately a factor of five. At right, the color has been overlaid onto the LORRI image to show the color uniformity of the Ultima and Thule lobes. Note the reduced red coloring at the neck of the object.

Зонд New Horizons передал первые детальные снимки астероида Ultima Thule
ВАШИНГТОН, 2 янв - РИА Новости. НАСА в среду опубликовало первые детальные снимки астероида Ultima Thule, сделанные зондом New Horizons с расстояния 27 тысяч километров: космическое тело предстало на них в виде "снеговика".
Американский зонд New Horizons 1 января пролетел рядом с астероидом 2014 MU69 Ultima Thule на самой окраине Солнечной системы. По расчетам, расстояние между зондом и астероидом в момент максимального сближения составило всего 3,5 тысячи километров. Небесное тело из пояса Койпера стало самым дальним от Земли объектом, посещенным земным зондом. Зонд пронесся мимо Ultima Thule со скоростью 32 тысячи миль в час (51 тысяча километров в час или около 14,6 километра в секунду).
Представленные НАСА снимки стали первым детальным изображением самого удаленного от Земли объекта, когда-либо исследованного человеком. Снимки, на которых астероид предстал как две сросшихся сферы и похож на немного покосившийся снеговик, были сделаны с расстояния почти 28 тысяч километров. По данным НАСА, длинна астроида составляет 31 километр, "нижний" шар "снеговика" ученые назвали Ultima, его поперечная длина составляет 19 километров, другой шар - Thule - 14 километров. Исследователи предполагают, что они срослись еще на заре формирования Солнечной системы, слегка столкнувшись друг с другом. Космическое тело имеет красноватый оттенок. Представленные фотографии были сделаны через 30 минут после сближения зонда с астероидом, сообщили в ведомстве.

 Скрытый текст:

В НАСА уверены, что наблюдение за астероидом дает ученым возможность получить ответы на вопросы о начальном этапе формирования планет и рождения всей Солнечной системы.
Зонд продолжает передавать данные на Землю и, рассчитывают в НАСА, благодаря этому будут получены снимки еще более детального разрешения.
Астероид 2014 MU69 был открыт с помощью орбитального телескопа "Хаббл", об открытии было объявлено в 2014 году. В марте 2018 года НАСА по итогам интернет-голосования предварительно нарекло его Ultima Thule, что означает "Край света". Как отмечают в НАСА, до сих пор исследователям крайне мало известно об этом космическом теле, поэтому они рассчитывают больше узнать в результате полученных в ходе сближения данных. Ученые рассматривают это как "археологические раскопки Солнечной системы", рассчитывая получить данные о том, как подобные космические тела формировались, есть ли у них спутники и кольца.
New Horizons, который считается самым скоростным из когда-либо запущенных землянами космических аппаратов, был запущен в январе 2006 года. Год спустя он прошел мимо Юпитера на рекордно близком расстоянии в 2,3 миллиона километров, передав на Землю ценную информацию об атмосфере и магнитосфере планеты, а также данные о ее спутниках. После этого аппарат продолжил космическое путешествие в "спящем режиме" для сохранения возможностей находящейся на нем аппаратуры.

 Скрытый текст:

NASA's New Horizons mission arrived at Ultima Thule on 1 January 2019, at UTC. The Kuiper Belt object 2014 MU69, minor planet number 485968, was nicknamed "Ultima Thule" ("beyond the known world"). Ultima Thule measures approximately 30 km in diameter, and is irregularly shaped. New Horizons spacecraft flew by Ultima Thule at a distance of 3500 km (2200 miles). At that time, Ultima Thule was at a distance of almost 6.5 billion km (4 billion miles) from the Sun, making this the most distant planetary flyby that has yet been attempted, and the first time that a Solar System object of this type has been seen close-up.

По этой фотографии кажется, что ударные кратеры все-таки есть, несмотря на то, что владельцы снимка пишут обратное.
По крайней мере, если картинка не излишне сильно придумана компьютером, то несколько вмятин на "голове" снеговика и с десяток на "туловище" угадываются.

[Чебурашка]

Вот так из планетоземалей слипались планеты на заре Солнечной системы 

[sol]

э... я не понял? А с 3500 км. расстояния будут снимки? (даже и смазаные после обработки покатят...)
Или вишенку на торте берегут?

[sol]

А так - снеговик снеговиком. Как раз новогодний сюрприз! Теперь понятно - откуда Санта Клаус.... 6)

[Чебурашка]

Сегодня обещают более детальные снимки.
