New 3D map shows 'empty' space is restless, not calm

نئی تھری ڈی نقشہ سازی: 'خالی' خلا پرسکون نہیں، بے چین ہے

नए 3डी मानचित्र से पता चला: 'खाली' अंतरिक्ष शांत नहीं, बेचैन है

New 3D map shows 'empty' space is restless, not calm

Key points

اہم نکات

मुख्य बातें

  • A new three-dimensional map of the space between stars suggests that supposedly 'empty' space is far more restless than textbooks assumed.
  • By combining a 2024 dust map covering a sphere more than 4,000 light-years wide around the Sun with a map of ultraviolet radiation, researchers found that 27 percent of the nearby interstellar medium was cold, 32 percent warm, and 41 percent in an unstable in-between state.
  • That challenges a model from 1969 and may help explain why galaxies turn gas into stars so slowly.
  • ستاروں کے درمیان خلا کی نئی تھری ڈی نقشہ سازی سے لگتا ہے کہ نام نہاد 'خالی' خلا نصابی کتابوں کے تصور سے کہیں زیادہ بے چین ہے۔ سورج کے گرد 4,000 نوری سال سے زیادہ چوڑے دائرے کی 2024 کی گرد کی نقشہ سازی کو الٹرا وائلٹ تابکاری کے نقشے سے ملا کر محققین نے پایا کہ قریبی بین النجمی مادے کا 27 فیصد سرد، 32 فیصد گرم اور 41 فیصد غیر مستحکم درمیانی حالت میں تھا۔ یہ 1969 کے ماڈل کو چیلنج کرتا ہے اور یہ سمجھنے میں مدد دے سکتا ہے کہ کہکشائیں گیس کو ستاروں میں اتنی آہستہ کیوں بدلتی ہیں۔ یہ تجزیہ ابھی جائزے کے مرحلے میں ہے۔
  • तारों के बीच के अंतरिक्ष के नए त्रि-आयामी मानचित्र से लगता है कि तथाकथित 'खाली' अंतरिक्ष पाठ्यपुस्तकों की धारणा से कहीं अधिक बेचैन है। सूर्य के चारों ओर 4,000 प्रकाश-वर्ष से अधिक चौड़े क्षेत्र के 2024 के धूल मानचित्र को पराबैंगनी विकिरण के मानचित्र से मिलाकर शोधकर्ताओं ने पाया कि आसपास के अंतरतारकीय माध्यम का 27 प्रतिशत ठंडा, 32 प्रतिशत गर्म और 41 प्रतिशत अस्थिर बीच की अवस्था में था। यह 1969 के मॉडल को चुनौती देता है और यह समझने में मदद कर सकता है कि आकाशगंगाएँ गैस को तारों में इतनी धीरे क्यों बदलती हैं। यह विश्लेषण अभी समीक्षा के चरण में है।

By combining a 2024 dust map covering a sphere more than 4,000 light-years wide around the Sun with a map of ultraviolet radiation, researchers found that 27 percent of the nearby interstellar medium was cold, 32 percent warm, and 41 percent in an unstable in-between state. That challenges a model from 1969 and may help explain why galaxies turn gas into stars so slowly. The analysis is still undergoing peer review.
