  • brightness : 白度
  1. Analysis showed this might be due to the fact that a black hole passed in front of the star. the gravitation of a black hole can function as a convex lens and focus starlight, resulting in transience increase of apparent brightness of the star

    分析顯示，這很可能是因為有一個黑洞在恆星前面經過，黑洞的引力會聚了星光，就像凸透鏡把光線聚焦一樣，使恆星的視亮度增加。
  2. Deferring to historical custom, astronomers, measure the apparent brightness of stars through the magnitude scale, a very confusing way.

    按照歷史習慣，天文學家用星等標這種容易使人混淆的方法來度量恆星的視亮度。
  3. We found that the luminosities of type i supernovae are about the same. therefore, we can compute the distance to a galaxy by measuring the apparent brightness of a type i supernova in that galaxy, if we can find one

    科學家發現原來所有這種超新星爆發的光度都是差不多的，所以我們只要找到這種超新星，便可以由它的視亮度推算出它和地球的距離，從而得知它所處身星系的距離。
  4. During a penumbral lunar eclipse, only the apparent brightness of the moon will become dimmer but the limb of the moon will not be obscured by the earth s shadow

    在半影月食發生期間，月亮將略為轉暗，但它的邊緣並不會被地球的影子所阻擋。
  5. By gauging the redshift and apparent brightness of a large number of supernovae located at a variety of distances, researchers can create a record of the universe ' s expansion

    藉由調校大量位於不同距離的超新星紅移和表觀亮度，研究人員可造出一組宇宙膨脹的記錄。
