Summary[edit]
DescriptionA Stars Spiral.ogv |
English: NASA-supported researchers using a Japanese telescope in Hawaii have taken the first clear image of a rare sight: a star surrounded by a spiral-armed disk. Telescope images have shown hints of stars with spiral disks before. The clarity of this image, however, is allowing researchers to study what causes this kind of spiral. Rings called circumstellar disks—composed of gas, dust and an accumulation of small objects—surround some stars. If the ring contains planets, their gravitational pull could alter its circular form and create the spiral arms. This video take a closer look at the image of star SAO 206462 and raises the question of whether orbiting planets, or something else entirely, created this curious shape.
Українська: Дослідники, за підтримки НАСА за допомогою японського телескопа «Субару» на Гаваях, зробили перше чітке зображення рідкісного видовища: зірки SAO 206462, оточеної спіралеподібним диском. Ясність цього зображення, дозволяє дослідникам зробити висновки, що навколозоряні диски — складаються з газу, пилу і скупчення дрібних предметів, які оточують деякі зірки. Якщо кільце містить планети, їх гравітаційне поле може змінити кругову форму диску і створити спіральні рукави. |
