Astronomers using a previously captured Hubble imagery spotted a remarkable image of a young star’s unseen, planet-forming disk casting a huge shadow across a more distant cloud in a star-forming region. The star is called HBC 672, and the shadow feature was nicknamed the “Bat Shadow” because it resembles a pair of wings. The nickname turned out to be unexpectedly appropriate, because now those “wings” appear to be flapping!

天文学家利用之前哈勃望远镜拍摄到的照片,一颗年轻的恒星在其未被发现的形成行星的圆盘上投下了一个巨大的阴影,覆盖了恒星形成区域中较远的星云。这颗恒星被称为HBC 672,它的影子特征被称为“蝙蝠影子”,因为它像一对翅膀。原来这个绰号是出乎意料的合适,因为现在那些“翅膀”似乎在拍打!

好奇恒星怎么投阴影,阴影不是一个发光的东西照到物体上投出影子吗,那周围还有别的恒星比这颗恒星更亮?

是恒星的一颗未形成还是圆盘的早期行星投射的影子照在了更远的星云上
