Barnard's Star moving moving through space over ~5 decades. To make this GIF I used images
from the National Geographic Society's Palomar Observatory Sky Survey via the Digitized Sky
Survey, and the last frame is from the Sloan Digital Sky Survey. Barnard's star is a low-
mass dwarf that's only 6 light years away from us (hence the high relative motion versus other
stars), and is one of the oldest stars in our Milky Way Galaxy, at ~12 billion years old, and
if one excludes the Alpha/Proxima Centauri system, it's the next closest star to us.
