Here is a side-by-side comparison of views of our planet Earth taken from two different vantage points over more than four decades apart. The iconic "Blue Marble" view on the left was taken 43 years ago on December 7, 1972 from Apollo 17 on its way to the Moon. The view on the right is from Lagrangian Point L1, located approximately one million miles away from earth (about four times farther than the moon) and was provided by the Earth Polychromatic Imaging Camera (EPIC) sensor affixed to the Deep Space Climate Observatory (DSCOVR).
