For the first time observed the site that planet is seen as being born.

In from the birth of the dust of the disk surrounding the young star after about 100 million years, such as the site the National Astronomical Observatory of Japan, which is seen as the planet is born for the first time was observed in the Alma telescope in Chile. That outcome understanding of the birth and formation process of planet progresses by leaps and bounds.
Around the birth shortly after stars, there is a disk made of dust and gas. Here over 1 million years, dust and coalesce repeated collisions, it was believed that the planet can.
The research team observed in October in the radio waves to "Taurus HL star" away about 450 light-years from Earth. Dust disk is I caught clearly how surrounding the star over and over again. The size of the disk is about three times that of the solar system, I was successful in shooting in the corresponding highest ever resolution on "vision 2 thousand" of human beings.
Found that there are at least three black gap into a disk. Since could planet dust gathered in this place, along the orbit of the planet dust is reduced, that has a gap.
Birth from without until this theory and can young star of planets around after 100 million years, the research team has been "It's results that revolutionize the planet formation of research". I expect that the birth of the mechanism of the planet will be appreciated.



誕生から約１００万年後の若い恒星を取り囲むちりの円盤の中で、惑星が誕生しているとみられる現場を国立天文台などが南米チリのアルマ望遠鏡で初めて観測した。惑星の誕生や形成過程の理解が飛躍的に進む成果という。
　誕生間もない星の周囲には、ちりやガスでできた円盤がある。ここでは１千万年以上にわたって、ちりが衝突を繰り返して合体し、惑星ができると考えられていた。
　研究チームは地球から約４５０光年離れた「おうし座ＨＬ星」を電波で１０月に観測。ちりの円盤が幾重にも星を囲んでいる様子を鮮明に捉えた。円盤の大きさは太陽系の約３倍で、人間の「視力２千」に相当する史上最高の解像度で撮影に成功した。
　円盤には少なくとも３本の黒い隙間があることが判明。この場所でちりが集まって惑星ができたため、惑星の公転軌道に沿ってちりが減少し、隙間ができたという。
　誕生から１００万年後の若い星の周囲で惑星ができるとの理論はこれまでなく、研究チームは「惑星形成の研究に革命をもたらす成果だ」としている。惑星の誕生のメカニズムが理解されることを期待します。
