اكتشاف مثير حـول أول ثقب أسـود مكتشف على الإطلاق…!
كشــفت دراســة جــديدة أن الثــقب الأســود الــهائــل الــذي يــبعــد 7200 ســنة ضــوئيــة عــن الأرض، أكبــر بنــســبة %50 مــما كــان مــتوقعا في الأصــــل، وأطــلق علــيه اســــم “Cygnus-X-1″، وكــان أول ثقــــب أســود أكــده عــلماء الفـــلك، بــعد اكــتشافــه لأول مــرة فــي عــــام 1964 عنــدما تم إرســال عــدّادي “Geiger” إلى الفــــضاء على صــــاروخ.
وبــفضل مجمــوعة مــن التــقنــيات…

This is the Running Chicken Nebula! 🐔🐔🐔
This nebula should technically look all red in the image but some coloration became weird and it came out really nicely with its c o l o r f u l appearance! This nebula is a powerful star forming region known for its clumps of dark dust known as Thackeray’s Globules. 🌈🌈🌈

“a CME the size of the 1859 Carrington Event would, if not prepared for, effectively level the power grid of the United States… Can we actually provide a full day’s worth of warning? Is a sufficient warning period actually significant enough to allow us to survive a Carrington class [event?] …if a Carrington class event were to be detected tomorrow, would we actually be able to survive it effectively?”
It was really only a few days ago that we saw the disastrous effects of what happens if freezing temperatures and power outages occur in a place that isn’t prepared for it. Well, what happens if a space weather event occurs that knocks out power grids globally, potentially not just for days but for months at once?
