📡 کشف آب در کرهٔ ماه 🔗؛

🔘 تیمِ تحقیقاتی وابسته به ناسا، با استفاده از رصدخانهٔ SOFIA و دوربین‌های فروسرخ، طول موج منحصر به مولکول‌های آب رو در گودال جنوبی ماه و سمت روشنِ آن، شناسایی کردن. دانشمندها دو دلیل عمده برای شکل‌گیری [مولکول‌های] آب ارائه دادن؛ ۱) برخوردِ مداوم شهاب‌سنگ‌های کوچک و انتقال حجم کمی از آب به درون خاک.

🔘 ۲) فرآیندی دو مرحله‌ای به کمک بادها و تشعشعات خورشیدی که در اثر اون هیدروژن به ماه منتقل میشه و سپس در اثر واکنش شیمیایی با موادِ معدنیِ حاویِ اکسیژن، ترکیب هیدروکسیل (یک اتم هیدروژن و یک اتم اکسیژن) شکل می‌گیره؛ و در نهایت منجر به تشکیل مولکول‌های آب میشه.

🔘 با پرواز در ارتفاع بیش از ۱۳ کیلوکتری از سطح زمین، رصدخانهٔ SOFIA، در مقایسه با سطح زمین، دید واضح‌تری از جهانِ فروسرخ خواهد داشت. با پرواز در اون ارتفاع، این رصدخانه با قطر آینهٔ ۲۶۹ سانتی‌متری بر فراز بیش از ۹۹ درصد بخار آب موجود در اتمسفر زمین قرار می‌‌گیره. 🌐
