Las galaxias

What is that big collection of gas, dust, and stars floating far beyond Earth's atmosphere? It's a galaxy! With the help of vibrant images and factual, elementary-level STEM text translated into North American Spanish, this nonfiction astronomy title for children examines the history of galaxies, their age, location, composition, and formation. It also explores how they were discovered. A space science feature spotlights galaxies as windows to the past. Captions, on-page definitions, and an index support readers in grade 2 and up.
