And beyond time and space for a thousand years, it was found that new fact.

The supernova SN1006 the poet of the Kamakura period, Fujiwara Teika was wrote diary "bright moon Symbol", a team of Harvard and Kyoto is using X-ray satellite "Suzaku", a detailed look at the time of the explosion in 1006 were elucidated.
Achievements leading mechanisms and the stars explode, also to elucidate the structure and scale of the universe, Koyama professor emeritus at Kyoto University was to be "feel the romance that it is beyond time and space for a thousand years, it was found that new facts".
The team observed in the Suzaku supernova remnants. It was confirmed that the spread elemental sulfur and iron, and silicon scattered in explosion biased in one direction.
Since none has been considered a substantially constant brightness of the explosion supernova of this type, it has been a yardstick to measure the distance from the earth. One of the basis of the research results was awarded the Nobel Prize in Physics for the expansion of the universe and has accelerated with rang, if there is a bias in the way of the spread of material scattered at the time of the explosion, is a difference in brightness depending on the direction of observing to exit, that may affect the study.
Teika was not born at the time, was the description of the purpose of the "there was a star unfamiliar very bright" as the astronomical phenomenon of the past to the bright moon mentioned. But I was able to unravel the events that happened in the past thousand years. I feel exactly the romance.


鎌倉時代の歌人、藤原定家が日記「明月記」に書き記した超新星ＳＮ１００６が、１００６年に爆発したときの詳しい様子を、京都大と米ハーバード大のチームがエックス線衛星「すざく」を使って解明した。
　星が爆発するメカニズムや、宇宙の規模と構造の解明にもつながる成果で、京大の小山名誉教授は「千年の時空を超え、新しい事実が分かったことにロマンを感じる」とした。
　チームは超新星の残骸をすざくで観測。爆発で飛散した鉄や硫黄、ケイ素などの元素が一方向に偏って広がっていることを確認した。
　このタイプの超新星はどれも爆発時の明るさがほぼ一定とされていたため、地球からの距離を測る物差しとなってきた。宇宙の膨張が加速しているとするノーベル物理学賞を受賞した研究成果の根拠の一つともなったが、爆発時に飛散する物質の広がり方に偏りがあれば、観測する方向によって明るさに差が出るため、研究に影響を及ぼす可能性があるという。
　定家は当時生まれていなかったが、明月記には過去の天文現象として「非常に明るく見慣れない星があった」との趣旨の記載をした。千年も過去に起きた出来事を解明できるんですね。まさにロマンを感じますね。
