Night Skies and National Parks This composite image of the U.S. The image taken by Meteosat Third Generation Imager 1. Believe it or not, this infrared image taken by NASA's Spitzer Space Telescope highlights a nursery for hundreds of baby stars. The data revealed that beneath Europa's icy surface, there is evidence of a hidden and global ocean. Europes newest weather satellite has snapped an image of the Earth that reveals our planets incredible beauty, despite gathering clouds. However, this image dates back to the late 1990s when the Galileo spacecraft explored the Jovian system, capturing several amazing images of Europa. Today's NASA Astronomy Picture of the Day even brings a stunning view of Europa by Galileo spacecraft. Interestingly, Europa is a popular destination as it has been visited by several spacecraft and more missions are planned in the future. This is because Europa's surface is composed of water ice that reflects approximately 5.5 times more sunlight than our Moon does. Europa is said to be about 90 percent the size of Earth's Moon! If we were to replace our Moon with Europa, it would have a similar apparent size in the sky, but it would be significantly brighter, NASA explains. Jupiter is the second planet in our solar system with the most number of moons at 95! Among these, the smallest of Jupiter's four Galilean moons is Europa which is the sixth closest to the planet.
