ملخص الخبر

  • رصد تلسكوب راديوي صيني سحابة هيدروجين في منطقة خالية من المجرات الظاهرة على مسافة 114 مليار مليار كيلومتر.
  • تشير حركة الغاز في السحابة إلى وجود كتلة خفية ضخمة من المادة المظلمة تحافظ على تماسكها.
  • يرجح العلماء أن السحابة تمثل مجرة مظلمة لم تنجح في تكوين نجوم بسبب تأثير الإشعاع فوق البنفسجي في الكون المبكر.
  • تعد السحابة من أوضح المرشحين لهذه الفئة النادرة، بانتظار تصوير أعمق لتأكيد ما إذا كانت خالية تماما من النجوم.

ملخص كتبه الذكاء الاصطناعي من نص الخبر في مصدره.

التقط أكبر مرصد راديوي في الصين إشارة غازية في موضع لا تظهر فيه مجرة، ثم كشف تحليل الحركة عن لغز أكبر من السحابة. هل عثر العلماء على عالم لم تولد فيه نجوم قط؟
