NASA released this Hubble Space Telescope image of the Eagle Nebula’s “Pillars of Creation” on 1/6/15. After comparing photos taken in 1996 and 2014, astronomers noticed that a narrow jet-like feature that may have been ejected from a newly forming star expanded its length over the nearly 19 year period.
