May have been evaporated by disintegrating into pieces.

The early morning of the 29th , Aeson comet that attracted the attention that it is becoming the " comet of the century " is closest to the sun , but the National Aeronautics and Space Administration (NASA) is a possibility that by the heat of the sun , and evaporated disintegrate into pieces I showed the view that there is . It was expected long tail is visible to the naked eye in early December .
It has been seen 4 o'clock am on the 29th , about 1.1 million kilometers shorter than the diameter of the sun up close to the surface of the sun , while being exposed to strong heat and gravity , Aeson comet came from distant solar system is passing through .
NASA was planning to observe by satellite before and after the moment and Aeson comet is closest to the sun . However , it is determined that there is a possibility that the collapsed because it did not show up at the track to be expected .
Main component in the ice , it is said to be " dirty snowball " such as sand stuck to the surface , the main body of the comet appears to be the tail gas and dust ejected violently are roasted in the sun shines . I was planning to elucidation of the comet component to be analyzed in detail Gasuya dust , National Astronomical Observatory of Japan and NASA and is keeping the state of the early solar system was born .
And I was expecting it to be observable at high position if accustomed to December , but it is regrettable . It is not be helped in the dirty snowball .


「世紀の彗星」になるのではと注目を集めたアイソン彗星が２９日未明、太陽に最も近づいたが、米航空宇宙局（ＮＡＳＡ）は太陽の熱によって、ばらばらに崩壊して蒸発した可能性があるとの見方を示した。１２月上旬には長い尾が肉眼で見えると期待されていた。
　太陽系の遠方からやってきたアイソン彗星は２９日午前４時ごろ、太陽の直径より短い約１１０万キロまで太陽の表面に近づき、強い重力や熱にさらされながら、通過するとみられていた。
　ＮＡＳＡはアイソン彗星が太陽に最接近する瞬間やその前後を人工衛星で観測する計画だった。しかし、予想される軌道に姿を見せなかったため崩壊した可能性があると判断した。
　彗星の本体は主成分が氷で、表面に砂などが付いた「汚れた雪だるま」と言われ、太陽にあぶられ激しく噴出したガスやちりが光って尾に見える。ＮＡＳＡや国立天文台はガスやちりを詳細に分析、太陽系が生まれた初期の状態を保っているとされる彗星の成分解明を計画していた。
　12月になれば高い位置で観測できると期待していたのですが残念です。汚れた雪だるまではしょうがないですね。
