The shape on the left is the front of the sticker, shaped like a circle. The background is Europa, with the top of the sticker showing Europa's surface, which then fades into black halfway down the background. The bottom half of the image is black. The image of Europa is well known. It is a light pink surface with orange/rust colored lines crisscrossing the surface in unique patterns. Overlayed on the black is the text "EUROPA". 

The right is a white circle that is the back of the sticker. It says "EUROPA" at the very top. Under that, it has descriptive text: "Europa - one of Jupiter's moons - is one of the most intriguing bodies in our solar system. Sandwiched between its icy outer shell and rocky mantle flows a global salty ocean that is twice the volume of all Earth's oceans combined. Why does this matter? On Earth, wherever we find water, we find life. While Europa's surface is cold, the moon generates enough internal heath as it is tugged and flexed by Jupiter's gravity to keep the ocean from freezing. This tidal flexing also generates stresses that can fracture and deform the surface, creating Europa's ridges, bands, and disrupted iceberg-like areas. Europa's astonishing geology and astrobiological potential make it a fascinating destination for exploration". Under that, there is a link to, and then The NASA name and meatball logo are at the very bottom.
