Black Holes

Black holes are some of the most mysterious objects in the universe. They have a
gravitational pull that's so strong, nothing can escape them. Black holes grow larger
by attracting anything that's near them, including entire stars! This book takes readers on an exciting out-of-this-world voyage and uncovers cutting-edge technology while supporting STEM and NGSS standards. Each book contains fact boxes, sidebars, a glossary, an index, and places to go for more information.
