ثقب أسود موجود في مركز مجرتنا !

الصورة الأولى (اليمين) ثقب أسود موجود في مركز مجرتنا (درب التبانة) حوالي ٤،٣ مليون ضعف كتلة الشمس. النقطة الموجودة في مركز الصورة الأولى هي تجسيد لمقارنة حجم الشمس مقابل الثقب الأسود. الدائرة المرسومة حول الثقب الأسود تمثل مدار كوكب عطارد حول نجم الشمس.

الصورة الثانية لثقب أسود يبعد حوالي ٥٥ مليون سنة ضوئية عن المجموعة الشمسية وتصل كتلته إلى ٦،٥ مليار ضعف كتلة نجم الشمس. في الصورة الثانية نجد أن نجم الشمس لا يمكن أن يظهر كمقارنة في الحجوم ونجد أن الدائرة الموجودة في مركز الصورة هي تمثيل لمدار كوكب بلوتو القزم. أيضاً نجد نقطة تمثل موقع مسبار فويجر ١ التي انطلق في عام ١٩٧٧ والذي يبعد حوالي ١٥ مليار ميل عن كوكب الأرض.
