В космосе наконец-то нашли следы самых первых молекул Вселенной

Ученые давно подозревали, что примерно через 100 000 лет после Большого Взрыва гелий и водород объединились, образовав первую молекулу — гидрид гелия. Это помогло Вселенной начать остывать, что привело к формированию звезд. Однако, несмотря на десятилетия поисков, ученые никак не могли найти гидрид гелия в космосе. До нынешнего момента. Теперь гидрид гелия нашли в туманности NGC 7027 с помощью крайне хитроумного изобретения.

Гидрид гелия: свидетель рождения первых звезд

В космосе наконец-то нашли следы самых первых молекул Вселенной

NASA использовало свою Стратосферную обсерваторию для инфракрасной астрономии (SOFIA), чтобы найти эту древнюю молекулу. Ученые нашли ее в NGC 7027, планетарной туманности (это останки звезды вроде нашего солнца) в 3000 световых годах от нас. Открытие доказывает, что гидрид гелия может существовать в космосе и это подтверждает теории о химии ранней вселенной и ее эволюции. Результаты были опубликованы в Nature.

Это открытие также свидетельствует о мощи новейших технологий NASA. SOFIA — это самая большая в мире воздушная обсерватория. По сути, она представляет собой модифицированный самолет Boeing 747SP, который возвращается после каждого полета. Это позволяет NASA добавлять новые инструменты по мере их появления. Недавнее обновление приемника на терагерцевых частотах (GREAT) помогло открыть, собственно, наличие гидрида гелия в космосе. Ученые настроили инструмент на частоту молекулы и провели поиск в NGC 7027 — о том, что молекула может быть в этой туманности, начали подозревать еще в 1970-х годах. Как сказал в пресс-релизе директор научного центра SOFIA Гарольд Йорк, молекула там была всегда — нам просто не хватало нужных инструментов, чтобы ее найти.

Как думаете, что еще сможет найти SOFIA? Расскажите в нашем чате в Телеграме.

    First of all I would like to say excellent blog! I had a quick question in which I’d like to ask if you don’t mind. I was curious to find out how you center yourself and clear your head prior to writing. I have had trouble clearing my mind in getting my ideas out. I do take pleasure in writing but it just seems like the first 10 to 15 minutes tend to be wasted just trying to figure out how to begin. Any recommendations or hints? Thanks!

    I?m amazed, I must state. Really hardly ever do I encounter a blog that?s both educative and amusing, and also let me tell you, you have hit the nail on the head. Your concept is outstanding; the problem is something that insufficient people are speaking intelligently about. I am very pleased that I came across this in my look for something connecting to this.

  18. I’m really enjoying the design and layout of your blog. It’s a very easy on the eyes which makes it much more pleasant for me to come here and visit more often. Did you hire out a developer to create your theme? Exceptional work!

  19. 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. I’ve been using WordPress on a variety of websites for about a year and am concerned about switching to another platform. I have heard fantastic things about blogengine.net. Is there a way I can transfer all my wordpress content into it? Any help would be really appreciated!

  21. I know this if off topic but I’m looking into starting my own blog 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 internet smart so I’m not 100 certain. Any suggestions or advice would be greatly appreciated. Appreciate it
