Modern astrophysics is a rapidly developing science that uses the latest (and very expensive) instruments and supercomputers. This leads to a huge stream of results: exoplanets and dark energy, gravitational waves and the first close-up images of Pluto. As a result, the astronomical picture of the world is constantly changing. However, many of the fundamental features of this picture have already taken shape. We know that we live in an expanding universe that is a little less than 14 billion years old. We know how the nuclei of elements were formed and are formed. We can observe different stages of the formation of stars and planetary systems. You can even see how planets form in disks around stars. However, many questions and mysteries remain. What is dark matter and dark energy? How do different types of supernovae explode? How are black holes arranged? Finally, is there still life in the universe, and what could it be?
