Four hundred years ago, Galileo Galilei first sent a powerful spyglass, which later became known as a "telescope," to the sky and discovered other worlds similar and not similar to ours. And today, the largest countries in the world are investing huge amounts of money in the development of space research - and not only to satisfy the curiosity of scientists. The study of the Universe is the most advanced technology, ultra-sensitive optical and electronic devices, the latest information processing tools that push "earthly" progress.
