Cosmic debris trail hints at how our solar system could end

کائناتی ملبے کا راستہ بتاتا ہے کہ ہمارا نظام شمسی کیسے ختم ہو سکتا ہے

ब्रह्मांडीय मलबे का रास्ता बताता है कि हमारा सौरमंडल कैसे समाप्त हो सकता है

Cosmic debris trail hints at how our solar system could end

Key points

اہم نکات

मुख्य बातें

  • Astronomers have found a trail of debris around a white dwarf star about 1,600 light-years away that may show what the end of our own solar system could look like.
  • Observations with the European Southern Observatory's Very Large Telescope revealed two separate rings of gas around the dead star J1328-1450, likely the remains of a planetary system destroyed when the star swelled into a red giant and then collapsed.
  • The rings may have been shaped by two surviving planetary bodies, one only a few kilometres wide and another as large as Pluto or the Moon, though their existence is not yet confirmed.
  • ماہرین فلکیات نے تقریباً 1600 نوری سال دور ایک سفید بونے ستارے کے گرد ملبے کا راستہ دریافت کیا ہے، جو بتا سکتا ہے کہ ہمارے اپنے نظام شمسی کا انجام کیسا ہوگا۔ یورپی جنوبی رصدگاہ کی ویری لارج ٹیلی اسکوپ سے مشاہدے میں مردہ ستارے جے 1328-1450 کے گرد گیس کے دو الگ حلقے نظر آئے، جو ممکنہ طور پر اس سیاروں کے نظام کی باقیات ہیں جو ستارے کے سرخ دیو بننے اور پھر سکڑنے پر تباہ ہو گیا۔ یہ حلقے دو بچ جانے والے سیاروں نما اجسام سے بنے ہو سکتے ہیں — ایک صرف چند کلومیٹر چوڑا اور دوسرا پلوٹو یا چاند جتنا بڑا — اگرچہ ان کی موجودگی کی ابھی تصدیق نہیں ہوئی۔ تقریباً پانچ ارب سال بعد سورج بھی اسی راستے پر چلنے کی توقع ہے، سرخ دیو بن کر پھر سفید بونا رہ جائے گا، جس کے گرد بچا ہوا ملبہ ہوگا۔
  • खगोलविदों ने लगभग 1,600 प्रकाश-वर्ष दूर एक श्वेत बौने तारे के चारों ओर मलबे का रास्ता खोजा है, जो बता सकता है कि हमारे अपने सौरमंडल का अंत कैसा होगा। यूरोपीय दक्षिणी वेधशाला के वेरी लार्ज टेलीस्कोप से अवलोकन में मृत तारे जे1328-1450 के चारों ओर गैस के दो अलग वलय दिखे, जो संभवतः उस ग्रह प्रणाली के अवशेष हैं जो तारे के लाल दानव बनने और फिर सिकुड़ने पर नष्ट हो गई। ये वलय दो बचे हुए ग्रह जैसे पिंडों से बने हो सकते हैं — एक केवल कुछ किलोमीटर चौड़ा और दूसरा प्लूटो या चंद्रमा जितना बड़ा — हालाँकि उनकी मौजूदगी की अभी पुष्टि नहीं हुई है। लगभग पाँच अरब वर्षों बाद सूर्य के भी इसी रास्ते पर चलने की उम्मीद है, लाल दानव बनकर फिर श्वेत बौना रह जाएगा, जिसके चारों ओर बचा हुआ मलबा होगा।

Astronomers have found a trail of debris around a white dwarf star about 1,600 light-years away that may show what the end of our own solar system could look like. Observations with the European Southern Observatory's Very Large Telescope revealed two separate rings of gas around the dead star J1328-1450, likely the remains of a planetary system destroyed when the star swelled into a red giant and then collapsed. The rings may have been shaped by two surviving planetary bodies, one only a few kilometres wide and another as large as Pluto or the Moon, though their existence is not yet confirmed. In about five billion years, the Sun is expected to follow a similar path, swelling into a red giant before leaving behind a white dwarf surrounded by whatever debris survives.
