أقمار المشتري تسخن بعضها البعض
كشفت دراسة حديثة نشرت في مجلة جيوفيزيكال ريسيرتش ليترز، أن أقمار المشتري التي تعرف باسم أقمار غاليلو تسخن بعضها بظاهرة تسمى الاحترار القمري. على الرغم من بُعد أقمار المشتري عن الشمس، إلا أنها أكثر سخونة مما ينبغي، من المعروف أن هذه الأقمار الجليدية الجميلة تحتوي على مساحات داخلية دافئة بما يكفي لتشكيل محيطات من الماء السائل. وفي أعماق قمر آيو أكبر أقمار المشتري، تكون الحرارة شديدة لدرجة أنها تشكل محيط داخلي من الصهارة. كان الاعتقاد السائد أن المشتري هو السبب الوحيد وراء سخونة أقماره لكن وجدت الدراسة أن هذه الأقمار مسؤولة عن تسخين بعضها البعض، فهي تؤثر على بعضها بقوة…
