A bigger and sharper Hubble telescope photograph of the iconic Eagle Nebula's “Pillars of Creation” (R) is seen next to the original 1995 Hubble picture in this NASA image released January 6, 2015. By comparing the 1995 and 2014 pictures, astronomers also noticed a lengthening of a narrow jet-like feature that may have been ejected from a newly forming star. Over the intervening 19 years, this jet has stretched farther into space, across an additional 60 billion miles, at an estimated speed of about 450,000 miles per hour, according to a NASA news release.
