NASA has released an amazing animation showing how we’ve been seeing more and more of Pluto over the course of several decades, as newer and newer technologies emerged. The first frame is a digital zoom-in on Pluto by its discoverer Clyde Tombaugh from 1930 (image courtesy Lowell Observatory Archives). The other images show various views of Pluto as seen by NASA’s Hubble Space Telescope beginning in the 1990s and NASA’s New Horizons spacecraft in 2015. The final sequence zooms in to a close-up frame of Pluto released on July 15, 2015. You can find the complete list of image credits here.
