Какого металла больше всего во Вселенной

Самым распространенным химическим элементом на нашей планете является углерод. Но в масштабах Вселенной Земля — лишь песчинка среди бескрайнего моря звезд и галактик. И в связи с этим становится интересным, а из чего состоит наша Вселенная? Что является основой далеких планет и астероидов? Какой элемент периодической таблицы самый главный?

Какого металла больше всего во Вселенной

Самый распространенный химический элемент во Вселенной

Если говорить о том, какой элемент самый распространенный во Вселенной, то тут все будет очень просто. На первом месте идет водород, затем гелий, кислород, неон и замыкает пятерку лидеров железо. А теперь давайте подумаем, какой элемент выбивается из общей картины.

Правильно! Железо! Почему? Да потому, что все остальные представители таблицы Менделеева, кроме железа, являются газами. А железо — это металл. Таким образом железо — это самый распространенный металл во всей Вселенной. При этом он и один из самых важных, ведь если газы формируют в основном атмосферу небесных тел, то железо является основой планет. А значит можно сказать, что если бы не было железа, то не было бы и большинства объектов во Вселенной.

Как ученые определили, что железо — самый распространенный металл во Вселенной

По сообщению журнала The Astrophysical Journal, группа астрохимиков из США пришла к такому выводу, рассчитав спектр поглощения кластеров железа. То есть ученые провели спектральный анализ удаленных объектов. Если не вдаваться в подробности, то объяснить это можно следующим образом.

Когда мы что-либо видим, это означает, что от этого объекта отражается свет и мы улавливаем эти световые волны. Свет – это смесь электромагнитных колебаний, и каждое колебание имеет свою длину волны, и, соответственно, свой цвет. Есть 7 основных цветов, а также оттенков и переходов между ними. Когда проводится спектральный анализ, изучается именно то, как химические элементы поглащают или отражают свет. В итоге получается спектрограмма. На основе получившейся картины можно сделать вывод о характеристиках испустившего свет объекта. Простой пример — радуга после дождя. Капли дождя разделяют свет, исходящий от Солнца.

Какого металла больше всего во Вселенной Спектрограмма. 1,4 — спектры натрия, 2,5 — спектры водорода, 3,6 — спектры гелия

Это интересно: Как будет умирать вселенная?

Где находится «космическое железо»

Большая часть железа Вселенной сконцентрирована внутри планет и в межзвездном газе. Кроме того, как показывает новое исследование, не мало железа находится в связи с углеродом, формируя особые молекулы, называемые полиинами. При этом ранее предполагалось, что эти самые полиины — это соединения углерода без примесей железа.

«Атомы железа объединяются в особые соединения с углеродом и основная проблема в том, что эти соединения имеют почти такой же спектр, что и чистые углеводороды. Поэтому ранее мы могли легко их проглядеть», — говорит ведущий автор исследования Фрэнк Тиммес

  24. I know this if off topic but I’m looking into starting my own weblog and was curious what all is needed to get set up? I’m assuming having a blog like yours would cost a pretty penny? I’m not very web savvy so I’m not 100 sure. Any tips or advice would be greatly appreciated. Cheers

    My developer is trying to persuade me to move to .net from PHP. I have always disliked the idea because of the costs. But he’s tryiong none the less.

Is there a way I can transfer all my wordpress content into it? Any help would be really appreciated!

  38. Have you ever thought about including a little bit more than just your articles? I mean, what you say is important and all. But just imagine if you added some great pictures or video clips to give your posts more, «pop»! Your content is excellent but with pics and videos, this blog could undeniably be one of the best in its field. Very good blog!
