草原“天眼”與彗星

2020-07-20 08:37來(lái)源：新華網(wǎng)

這是7月19日在明安圖觀(guān)測基地拍攝的星空。7月18日晚至19日凌晨，在位于內蒙古錫林郭勒盟正鑲白旗境內的國家天文臺明安圖觀(guān)測基地，尼歐懷茲彗星劃過(guò)天際。在明安圖觀(guān)測基地內，排列著(zhù)100面白色的拋物面天線(xiàn)。這個(gè)龐大的天線(xiàn)陣列便是草原“天眼”——明安圖射電頻譜日像儀。草原“天眼”持續接收太陽(yáng)射電輻射，然后由科研人員進(jìn)行數據分析研究，對空間環(huán)境監測、太陽(yáng)活動(dòng)預報均有重要作用。新華社記者連振攝
