Moon 3D Screensaver can be used also for educational purposes since each frame is based on real Moon photos. We are able to see craters, mountains relief and even the back side of the Moon which is invisible from the Earth. We will watch thousands of stars with real coordinates, colors and brightness. This screensaver provides astronomically accurate 3D model true photo-realistic image quality. Mars 3D Screensaver presents planet's red deserts, hurricanes and mountains. It gives you the chance to see the amazing space sunrises and sunsets in thin Martian atmosphere as well as the Phobos - the largest of the two barren rocks which are the Martian moons. Here also each frame is based on true NASA photos. Saturn 3D Screensaver presents the cold gas giant planet with it's famous icy ring and even the ring's shadow on the planet and planet's shadow on the rings system. The frames here are also based on real NASA photos so the screensaver can be used for educational purposes in "demo" mode. Jupiter 3D screensaver shows us the largest planet within the solar system. The enormous gas giant is much larger than the Earth. We will have the opportunity to see its numerous moons, to watch the layer of clouds which covers the planet and its awful storms. Like Saturn, Jupiter has icy ring but it is faint and almost invisible from the Earth. As in the above mentioned screensavers, here the frames are based on true NASA photos. Galaxy 3D Screensaver is created in accordance with modern galaxy theory. It shows the home of our Solar system and other billion stars and their planets, clusters and nebulas known as the Milky Way or just the Galaxy. All the objects in the Milky Way Galaxy orbit their common center of mass, called the Galactic Centre. There are two tiny galaxies called Large Magellanic Cloud and Small Magellanic Cloud that orbit the Milky Way. All these facts we can learn from Galaxy 3D Screensaver. But that is not all. Like real space travelers we will have the chance to leave the Solar system and travel on a fantastic space ship. Using modern technologies, the screensaver will make the simulation almost real. We will be able to see the bar-shaped core region surrounded by a disk of gas and stars that are forming four arm structures in a spiral shape - the so called Spiral arms. We will learn that the Solar system is situated within a smaller spiral arm, called the Orion Arm. We will have also the opportunity to see how the galactic disk is surrounded by halo of stars and globular clusters. We will see bright and dark nebulas and many, many far and unknown galaxies. We will have an extraordinary experience! All the above mentioned screensavers are based on true facts and can be used for educational purposes in "demo" mode. I believe that for our children will be much more interesting to see the planets on a computer than on a movie. Besides, here they will have the opportunity to travel and feel like astronauts and to discover new things. They are not just screensavers, they are screenteachers!
