The outer Solar System's first building blocks were mostly fire, not ice

بیرونی نظام شمسی کے پہلے بلاکس زیادہ تر آگ تھے، برف نہیں

बाहरी सौर मंडल के पहले निर्माण खंड ज़्यादातर आग थे, बर्फ़ नहीं

The outer Solar System's first building blocks were mostly fire, not ice

Key points

اہم نکات

मुख्य बातें

  • A Yale-led study in Nature Astronomy has found the first chemical evidence for what the outer Solar System's earliest solid bodies were made of.
  • Within the first million years, they were built from 83 to 92 percent chondrules, tiny rock beads forged by intense heat, with very little icy dust.
  • The team reached back through iron meteorites, using sulphur levels and the oxidation of iron as two independent tracers, and found only 8 to 17 percent icy matrix.
  • نیچر ایسٹرونومی میں ییل کی قیادت والی تحقیق نے پہلی کیمیائی شہادت دی ہے کہ بیرونی نظام شمسی کے ابتدائی ٹھوس اجسام کس چیز سے بنے تھے۔ پہلے دس لاکھ سالوں میں وہ 83 سے 92 فیصد کونڈرولز سے بنے تھے، یعنی شدید گرمی سے بنے چھوٹے پتھریلے دانے، اور ان میں برفیلا گرد بہت کم تھا۔ ٹیم نے آئرن میٹیورائٹس کے ذریعے سلفر اور آئرن کے آکسیڈیشن کو دو آزاد اشاروں کے طور پر استعمال کیا اور صرف 8 سے 17 فیصد برفیلی میٹرکس پائی۔ بعد کے اجسام میں برف زیادہ آئی، لیکن پہلے پلانیٹیسیملز زیادہ تر آگ سے بنے تھے۔
  • नेचर एस्ट्रोनॉमी में येल के नेतृत्व वाले अध्ययन ने पहली रासायनिक साक्ष्य दी है कि बाहरी सौर मंडल के सबसे शुरुआती ठोस पिंड किससे बने थे। पहले दस लाख वर्षों में वे 83 से 92 प्रतिशत कॉन्ड्र्यूल्स से बने थे, यानी तेज़ गर्मी से बने छोटे चट्टानी दाने, और उनमें बर्फ़ीली धूल बहुत कम थी। टीम ने लौह उल्कापिंडों के ज़रिए सल्फ़र और लोहे के ऑक्सीकरण को दो स्वतंत्र संकेतकों के रूप में इस्तेमाल किया और केवल 8 से 17 प्रतिशत बर्फ़ीला मैट्रिक्स पाया। बाद के पिंडों में बर्फ़ ज़्यादा आई, लेकिन सबसे पहले प्लैनेटेसिमल ज़्यादातर आग से बने थे।

The team reached back through iron meteorites, using sulphur levels and the oxidation of iron as two independent tracers, and found only 8 to 17 percent icy matrix. Later bodies took in more ice, but the very first planetesimals were remarkably fire-made.
