During a field trip to the Las Campanas Observatory in Chile, they confirmed its unique nature.

吉(Alex Ji)教授的指導下,學生們分析了斯隆數位巡天計畫(SDSS)的數據,從而發現了這顆編號為SDSSJ0715-7334的恆星。

The star is exceptionally "pristine," containing only 0.005% of the metals found in our Sun.

在前往智利拉斯康帕納天文台的實地考察期間,他們證實了該恆星的獨特性。

Interestingly, astronomers believe this star is an "immigrant," having originated in the Large Magellanic Cloud before migrating to the Milky Way.

這顯示它在首批大型超新星爆發前久,便由古老的氣體形成。

This discovery underscores the power of modern science, where accessible "big data" allows students to perform genuine research.

有趣的是,天文學家認為這顆恆星是一個「移民」,它原本誕生於大麥哲倫星雲,隨後才遷徙至銀河系。
