Transit Survey seeks armchair astronomers “凌日搜索計劃” 招募志愿者在家中參與太空觀測

Play audio file

“行星獵人下一代凌日搜索計劃(The Planet Hunters Next-Generation Transit Survey )” 正在招募志愿者在線參與太空觀測,安坐家中就能當 “天文學家”。該項目正在向公眾尋求幫助,查看五年來拍攝到的天空中最亮恒星的數(shù)字影像。

Queen's University is a key partner in the Next-Generation Transit Search, a collaboration between universities in Europe and South America focused on discovering unknown planets. 

英國貝爾法斯特女王大學是 “下一代凌日搜索計劃” 的重要合作伙伴,這是歐洲和南美洲一些大學間的合作項目,致力于發(fā)現(xiàn)未知的行星。

The team have collected data on the light levels of thousands of stars. They're looking for the moment when a star gets just slightly dimmer, which may indicate that a planet has temporarily blocked the light, known as a 'transit'.

研究小組已經(jīng)收集了成千上萬顆恒星的光照水平數(shù)據(jù)。他們正在尋找恒星稍微變暗的時刻,這可能表明有一顆行星暫時擋住了恒星的光,被稱作 “凌日現(xiàn)象”。

Computers have helped to find most of the relevant transits, but they can't be 100% accurate. Scientists are calling on volunteers to help sift through data looking for patterns that might just possibly indicate an undiscovered world.

電腦已經(jīng)幫助人們找到了大多數(shù)相關的凌日現(xiàn)象,但還做不到百分百準確??茖W家呼吁志愿者幫助篩選數(shù)據(jù),尋找可能預示有未知世界存在的固定模式。
