اكتشاف كوكب شبيه بالأرض

كوكب الأرض


var addthis_pub="tonyawad";



قالت صحيفة الإندبندنت البريطانية إنه تم اكتشاف أول كوكب يتمتع بمناخ معتدل يشبه مناخ كوكب الأرض، ويدور فى مدار حول نجم بعيد. ويقول علماء الفلك إن التقنيات التى استخدمت فى دراسة هذا الكوكب ربما تكون مهمة فى البحث عن العوالم المشابهة للأرض الموجودة فى نظامنا الشمسى.

وأشارت الإندبندنت إلى أن الكوكب الجديد الذى أُطلق عليه "كوروت 9 بى" هو من بين 400 كوكب آخر تدور حول نجوم، إلا أنه الأول الذى تتقارب درجة حرارته مع الأرض، وهو ما يجعل العلماء قادرين على دراسة خصائصه بشكل عميق.

ويدرو هذا الكوكب حول نجمه دورة واحدة كل 95 يوما، وتتراوح درجة حرارته ما بين عشرين إلى 160 درجة مئوية. واعتبرت كلير ماوتو، عضو بالفريق الذى حقق هذا الاكتشاف فى المرصد الأوروبى الجنوبى أن الكوكب الجيد بمثابة حجر رشيد فى فك ألغاز الأبحاق القادمة لعلم الفلك.
