Interstellar comet 3I/ATLAS's icy grains resemble our own solar system

بین النجمی دمدار ستارے 3I/ATLAS کے برفیلے ذرات ہمارے نظام شمسی جیسے نکلے

अंतरतारकीय धूमकेतु 3I/ATLAS के बर्फीले कण हमारे सौर मंडल जैसे निकले

Interstellar comet 3I/ATLAS's icy grains resemble our own solar system

Key points

اہم نکات

मुख्य बातें

  • A study using NASA's James Webb Space Telescope has found that the tiny ice grains streaming from interstellar comet 3I/ATLAS, now leaving our solar system, look surprisingly like those of icy worlds beyond Neptune in our own solar system.
  • The comet's ice shows a strong band near 3 microns but very weak bands near 1.5 and 2.0 microns, a pattern also seen in distant trans-Neptunian objects, suggesting its ice is mixed with more dust than in typical comets.
  • Researchers say the finding hints that the building blocks of planets around other stars may share the same kind of tiny ice grains as our solar system.
  • ناسا کی جیمز ویب اسپیس ٹیلی اسکوپ سے کی گئی ایک تحقیق میں معلوم ہوا ہے کہ بین النجمی دمدار ستارے 3I/ATLAS سے نکلنے والے برف کے چھوٹے ذرات، جو اب ہمارے نظام شمسی سے باہر جا رہا ہے، حیران کن طور پر نیپچون سے آگے ہمارے نظام شمسی کی برفیلی دنیاؤں جیسے ہیں۔ دمدار ستارے کی برف میں 3 مائیکرون کے قریب مضبوط علامت ہے لیکن 1.5 اور 2.0 مائیکرون کے قریب بہت کمزور علامتیں ہیں، یہی نمونہ دور دراز ٹرانس نیپچونین اجسام میں بھی دیکھا جاتا ہے، جس سے ظاہر ہوتا ہے کہ اس کی برف میں عام دمدار ستاروں سے زیادہ گرد ملی ہوئی ہے۔ محققین کا کہنا ہے کہ اس سے اشارہ ملتا ہے کہ دوسرے ستاروں کے گرد سیاروں کے بنیادی اجزا بھی ہمارے نظام شمسی جیسے برف کے چھوٹے ذرات پر مشتمل ہو سکتے ہیں۔
  • नासा के जेम्स वेब स्पेस टेलीस्कोप से किए गए एक अध्ययन में पाया गया है कि अंतरतारकीय धूमकेतु 3I/ATLAS से निकलने वाले बर्फ के छोटे कण, जो अब हमारे सौर मंडल से बाहर जा रहा है, आश्चर्यजनक रूप से नेपच्यून से आगे हमारे सौर मंडल की बर्फीली दुनियाओं जैसे हैं। धूमकेतु की बर्फ में 3 माइक्रोन के पास मज़बूत संकेत है लेकिन 1.5 और 2.0 माइक्रोन के पास बहुत कमज़ोर संकेत हैं, यही पैटर्न दूर के ट्रांस-नेपच्यूनियन पिंडों में भी देखा जाता है, जिससे पता चलता है कि उसकी बर्फ में सामान्य धूमकेतुओं से अधिक धूल मिली हुई है। शोधकर्ताओं का कहना है कि इससे संकेत मिलता है कि अन्य तारों के आसपास ग्रहों के निर्माण खंड भी हमारे सौर मंडल जैसे बर्फ के छोटे कणों से बने हो सकते हैं।
