محاكاة تعيد درب التبانة إلى طفولتها.. آلاف المجرات الصغيرة صنعت مجرتنا

ملخص الخبر

كشفت محاكاة حاسوبية أن مجرة درب التبانة نشأت من تفاعل واندماج آلاف الأنظمة المجرية الصغيرة خلال المليارات الأولى من عمر الكون.
استخدم الباحثون مشروع ميغاترون للتنبؤ بشكل المجرة المبكر ومقارنته بالنماذج النظرية مع ما ترصده التلسكوبات حاليا.
تضمنت المحاكاة عمليات فيزيائية معقدة مثل الجاذبية وديناميكا الغازات والإشعاع والكيمياء وتطور النجوم.
أظهرت النتائج أن المجرات القديمة قد لا تحتوي دائما على نجوم، كما كشفت عن دور نجوم الجمهرة الثالثة في التكوين الكيميائي للمجرات.

ملخص كتبه الذكاء الاصطناعي من نص الخبر في مصدره.

كشفات محاكاة حاسوبية أن درب التبانة نشأت وسط آلاف الأنظمة المجرية الصغيرة التي اندمجت وتبادلت الغاز والعناصر عبر مليارات السنين لتبني تدريجيا المجرة الحلزونية التي نعيش فيها اليوم.
