From where do these neutrinos come? The IceCube Neutrino Observatory near the South Pole of the Earth has begun to detect nearly invisible particles of very high energy. Although these rarely-interacting neutrinos pass through much of the Earth just before being detected, where they started remains a mystery. Pictured here is IceCube’s Antarctic lab accompanied by a cartoon depicting long strands of detectors frozen into the crystal clear ice below. Candidate origins for these cosmic neutrinos include the violent surroundings of supermassive black holes at the centers of distant galaxies, and tremendous stellar explosions culminating in supernovas and gamma ray bursts far across the universe. As IceCube detects increasingly more high energy neutrinos, correlations with known objects may resolve this cosmic conundrum — or we may never know.

來自哪裡的中微子？位於南極的冰立方中微子天文台（IceCube Neutrino Observatory）開始檢測到非常高能量的幾乎不可見粒子。儘管這些中微子在被檢測之前幾乎可以穿透地球的大部分，但它們的起源仍然是一個謎。這裡是冰立方的南極實驗室，附有一幅卡通圖，描繪了冷凍在晶瑩剔透的冰層下的長探測器纖維。這些宇宙中微子的可能起源包括遙遠星系中心超大質量黑洞周圍的劇烈環境，以及來自宇宙深處的驚人恆星爆炸，如超新星和伽瑪射線暴。隨著冰立方檢測到越來越多的高能中微子，若能與已知物體建立關聯，或許能解開這個宇宙之謎——否則我們可能永遠無法得知。 #中微子 #宇宙 #冰立方 #南極 #天文學家的探索 #高能粒子
