The universe is here

Astronomy is a science devoted to the study of what existed, exists and will exist, from the most elemental particle to the most massive and powerful galaxy one observes. The study of the universe is not only meant to be to achieve an important understanding about it, but also in other fields of science and technology. The most important contribution from astronomy is perhaps social: it fascinates millions of people along the globe. The history of astronomy carries along the very history of humankind.
