This is a spectacular image of a waning crescent Moon and Jupiter, which is seen at the bottom right of the image. The four sources of light around Jupiter are its four bright satellites namely - Ganymede, Callisto, Europa and Io. These satellites are known as the Galilean satellites as it was discovered by Galileo when he looked up at Jupiter for the first time in his newly formed telescope. The satellites can be seen clearly even through a small telescope.
