Dead star's double debris rings offer a glimpse of Earth's far future

مردہ ستارے کے دوہرے ملبے کے حلقے زمین کے دور مستقبل کی جھلک دیتے ہیں

मृत तारे के दोहरे मलबे के छल्ले पृथ्वी के दूर भविष्य की झलक देते हैं

Dead star's double debris rings offer a glimpse of Earth's far future

Key points

اہم نکات

मुख्य बातें

  • Astronomers have found a rare double ring of debris around a dead star, offering a glimpse of what may happen to our own Solar System when the Sun dies.
  • Using the European Southern Observatory's Very Large Telescope in Chile, researchers detected two concentric rings of gas around the white dwarf J1328-1450, separated by a clear gap — the first such complex structure seen around a dead star.
  • Scientists believe two surviving planetary bodies, one asteroid-sized and one Moon-sized, hold the rings in place.
  • ماہرین فلکیات نے ایک مردہ ستارے کے گرد ملبے کے دو نایاب حلقے دریافت کیے ہیں، جو اس بات کی جھلک دیتے ہیں کہ سورج کے مرنے پر ہمارے نظام شمسی کا کیا ہو سکتا ہے۔ چلی میں یورپی سدرن آبزرویٹری کی ویری لارج ٹیلی اسکوپ سے محققین نے سفید بونے ستارے جے 1328-1450 کے گرد گیس کے دو ہم مرکز حلقے دیکھے، جن کے درمیان واضح خلا ہے — یہ مردہ ستارے کے گرد اس طرح کا پہلا پیچیدہ ڈھانچہ ہے۔ سائنسدانوں کا خیال ہے کہ دو بچ جانے والے سیاراتی اجسام، ایک شہابیے جتنا اور ایک چاند جتنا، ان حلقوں کو قائم رکھے ہوئے ہیں۔ ملبے میں کیلشیم، آکسیجن اور میگنیشیم شامل ہیں، جو ہمارے نظام شمسی جیسے مواد ہیں، اور یہ نتائج نیچر ایسٹرونومی میں شائع ہوئے ہیں۔
  • खगोलविदों ने एक मृत तारे के चारों ओर मलबे के दो दुर्लभ छल्ले खोजे हैं, जो इस बात की झलक देते हैं कि सूर्य के मरने पर हमारे सौरमंडल का क्या हो सकता है। चिली में यूरोपीय दक्षिणी वेधशाला के वेरी लार्ज टेलीस्कोप से शोधकर्ताओं ने श्वेत बौने तारे जे1328-1450 के चारों ओर गैस के दो संकेंद्रित छल्ले देखे, जिनके बीच स्पष्ट अंतर है — यह मृत तारे के चारों ओर इस तरह की पहली जटिल संरचना है। वैज्ञानिकों का मानना है कि दो बचे हुए ग्रहीय पिंड, एक क्षुद्रग्रह जितना और एक चंद्रमा जितना, इन छल्लों को बनाए हुए हैं। मलबे में कैल्शियम, ऑक्सीजन और मैग्नीशियम शामिल हैं, जो हमारे सौरमंडल जैसे पदार्थ हैं, और ये निष्कर्ष नेचर एस्ट्रोनॉमी में प्रकाशित हुए हैं।

Astronomers have found a rare double ring of debris around a dead star, offering a glimpse of what may happen to our own Solar System when the Sun dies. Using the European Southern Observatory's Very Large Telescope in Chile, researchers detected two concentric rings of gas around the white dwarf J1328-1450, separated by a clear gap — the first such complex structure seen around a dead star. Scientists believe two surviving planetary bodies, one asteroid-sized and one Moon-sized, hold the rings in place. The debris contains calcium, oxygen and magnesium, materials similar to those in our Solar System, and the findings were published in Nature Astronomy.
