NASA показало загадочную Цереру в лучах Солнца

Ученые смогли детально рассмотреть поверхность ближайшей к Земле карликовой планеты.

Зонд Dawn сделал уникальные кадры карликовой планеты Цереры, которые помогли проследить за взаимодействием света Солнца с поверхностью планетоида, сообщается на сайте NASA.

Космический аппарат уже два года изучает Цереру, самый большой объект главного пояса астероидов между орбитами Марса и Юпитера. Интерес ученых к этому телу вызван тем, что она является зародышем планеты, остановившимся в развитии.

Первые снимки с зонда Dawn были получены весной 2015 года, вскоре после прибытия к планете. Тогда ученые обнаружили на фото необычные феномены — белые пятна в кратере Оккатор и гору Ахуна высотой четыре километра.

Позже ученые выяснили, что Ахуна не гора, а потухший криовулкан. Белые пятна же оказались источником временной атмосферы Цереры, состоящей из водных паров.

Кроме того, в некоторых частях планеты ученые нашли чистый лед. Это говорит о том, что поверхность Цереры постоянно обновляется, ведь эти льды должны были давно испариться в космос.

Для проверки всех этих фактов команда Dawn еще зимой начала серию очень сложных и продолжительных орбитальных маневров, благодаря которым удалось вывести зонд в точку, расположенную на прямой между Солнцем и Церерой.

Ученые называют эту точку «точкой оппозиции». Благодаря ней зонд смог получить достаточно много уникальных снимков кратера Оккатор и других регионов Цереры.

Новые снимки должны помочь ученым уточнить состав льда на карликовой планете и изучить его подробнее.

Также, планетологам удалось проследить, как свет Солнца взаимодействует с пылью и частицами грунта Цереры, и понять, насколько светлеет поверхность планеты при прямом освещении.

Эта информация, как объясняют ученые, позволяет очень точно оценить размеры частиц грунта, определить, как много в нем пор, и раскрыть многие другие важные свойства.

Ранее Dawn отправил новые детальные снимки «пирамиды» Цереры — загадочной горы Ахуна.

  6. Maybe someone can help me. I want to create a website with a focus on current events in education. I plan to write from my website articles and even published literature. The articles I write will be reviews and criticisms from published articles. I am aware of the Fair Use Doctrine and I can write reviews and provide ‘fair and reasonable criticism’ without license or approval from the author’s original material as long as I cite and provide references to the original author. My website will also have either sponsors or advertise products within it. But not related directly to the articles I write. Most likely advertisement for products I like. For example, a particular software product I like. My question is: Just by having this website «for profit»; am I in violation of the Fair Use Doctrine or have a copyright infringement because my website is for profit from the published material I write …OR not because the material I write about is not in any way having a copyright infringement upon my sponsors or advertisements even though my website is for profit (In other words, is there any connection or relationship between my sponsors (or advertisements) and my published articles regarding copyright infringement with a for profit website)? Please reply. Thanks!.
