This video zoom sequence starts with a wide-field view of the bright constellation of Leo (The Lion) and slowly closes in on what looks like an unremarkable faint star. This ancient star is called SDSS J102915+172927 and has been found to have the lowest amount of elements heavier than helium of all stars yet studied. It has a mass smaller than that of the Sun and is probably more than 13 billion years old.
這套視頻由光亮的獅子座的寬場景開始變焦序列,及慢慢地靠近一顆看來不起眼的暗星。這顆古老的恆星被稱為 SDSS J102915172927,並已被發現有最低數額的元素比所有迄今研究過的星體的氦更重。它有小於太陽的質量及可能超過 13億年。
