This animation combines various observations of Pluto over the course
of several decades. The first frame is a digital zoom-in on Pluto as it
appeared upon its discovery by Clyde Tombaugh in 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.
