Mercury Two Views of Mercury
Which of these images makes it easier to see craters on Mercury? Both images show the same part of the planet and are valuable to scientists in different ways. If you were to see Mercury with your own eyes, it would look a lot like the grayish image with white spots on the left. For the image on the right, Mercury's subtle differences in color were "stretched" or enhanced to help scientists see how impact craters and past volcanic eruptions have changed the surface of Mercury.

Both images were taken by NASA's MESSENGER spacecraft.
