The book is devoted to an extremely fascinating subject, which, unfortunately, has recently been excluded from the school curriculum - astronomy. The reader will get an idea of ​ ​ the nature of the Universe, about stellar and planetary systems, about ice dwarfs and fire giants, about nebulae, stardust and other amazing objects, learn many interesting facts and, possibly, learn to think on a cosmic scale. The book is addressed to everyone who likes to look at the starry sky on a clear night.
