Iconic Eagle Nebula, Hubble telescope photograph. 標誌性的鷹狀星雲, 哈勃望遠鏡的照片

A Hubble telescope photograph of the iconic Eagle Nebula's "Pillars of Creation" is seen in this NASA image released January 6, 2015. By comparing 1995 and 2014 pictures, astronomers noticed a lengthening of a narrow jet-like feature that may have been ejected from a newly forming star.
