Io and Europa from New Horizons (Emily Lakdawalla's version)
Io and Europa from New Horizons (Emily Lakdawalla's version) An iconic image from the New Horizons flyby of Jupiter in 2007, showing Io and Europa together. Io's nightside is visible thanks to Jupitershine. Europa is closer to New Horizons than Jupiter, so the portion of its night side visible to New Horizons is not Jupiterlit.

The image is composed of color MVIC data draped over more detailed grayscale LORRI data. The moons are in the positions they occupied when the MVIC image was taken.
