蝎虎座的恒星比星系更耀眼

A little-studied star, TYC 3203-450-1, upstages a galaxy in this Hubble Telescope image from December 2017. Both the star and the galaxy are within the Lizard constellation, Lacerta. However, the star is much closer than the much more distant galaxy.

Astronomers studying distant objects call these stars “foreground stars” and they are often not very happy about them, as their bright light is contaminating the faint light from the more distant and interesting objects they actually want to study.

在这张2017年12月哈勃望远镜拍摄的图像中，一颗未被研究的恒星TYC 3203-450-1占据了星系的上风。这颗恒星和星系都位于蝎虎座内。然而，这颗恒星比远得多的星系更近。

研究遥远物体的天文学家称这些恒星为“前景恒星”，天文学家通常对它们不太满意，因为它们的明亮光线污染了它们实际想要研究的更遥远和有趣物体的微弱光线。
