مخطوطات صينية حول كسوف شمسي تكشف أسرار دوران الأرض

كشفت دراسة يابانية لوثائق صينية تعود إلى عام 709 قبل الميلاد تفاصيل جديدة عن دوران الأرض والنشاط الشمسي قبل نحو 2700 عام. وبعد تصحيح خطأ في الإحداثيات الجغرافية لموقع رصد الكسوف، تمكن الباحثون من إعادة بناء مساره بدقة، وتصحيح حسابات دوران الأرض حول محورها. كما أتاح وصف تاريخي للإكليل الشمسي استنتاج أن الشمس ربما كانت قريبة من ذروة دورة نشاطها التي تستمر نحو 11 عاماً.
