Second round of direct observation to the success of the gravitational wave.

Research team, such as California Institute of Technology is 15 days, the black hole is direct observation of the second round of gravity waves generated when combined
It announced that it had succeeded in.
 In feat following the success of the first observation, which was announced in February this year, advance and elucidation of difficult was the black hole of the mechanism in a conventional telescope
It is expected that.
According to the research team, a giant observation device called a "LIGO" which is in the western United States and southern, each December last year
Detects a distortion of space-time can be seen with the gravity wave in 26 days. Mass 14-fold and 8-fold in the black hole of the sun coalesced to 14 million years ago
When in, distortion of energy corresponding to the mass of one piece of the sun spread in the universe as a gravitational wave, believed to have arrived on Earth.
For the second time of observation success, Chad Hanna Dr. of Pennsylvania State University research team (to observe the universe with gravitational waves) "
Future of gravitational wave astronomy has been pointed out that bright's achievement that can be confident that ".
We hope that the mystery of the universe is going to be elucidated through the observation of gravitational waves.



 米カリフォルニア工科大などの研究チームは１５日、ブラックホールが合体した時に発生した重力波の２回目の直接観測に成功したと発表した。
 今年２月に発表した初観測の成功に続く快挙で、従来の望遠鏡では難しかったブラックホールの仕組みの解明などが進む
と期待される。
　研究チームによると、米国西部と南部にある「ＬＩＧＯ」と呼ばれる巨大観測装置で、それぞれ昨年１２月
２６日に重力波とみられる時空のゆがみを検出した。質量が太陽の１４倍と８倍のブラックホールが１４億年前に合体した
際に、太陽１個分の質量に相当するエネルギーのゆがみが重力波として宇宙に広がり、地球に届いたとみられる。
　２度目の観測成功に、研究チームのペンシルベニア州立大のチャド・ハンナ博士は「（重力波を使って宇宙を観測する）重力波天文学の将来が明るいと確信できる成果だ」と指摘している。
　重力波の観測を通じて宇宙の謎が解明されていくことを期待します。
