This is a very good book. But it covers too much, meaning each topic is very minimally covered. There are 158 pages about the night sky, the constellations, the monthly sky guide. Those 158 pages should belong to a different book. Those 158 pages should have been used to show more about planets and galaxies. Half a page on Hubble, one page on Europa, two pages on Andromeda galaxy. One should expect more in a book about the universe.
