Black Holes Explained
On December 26, 2015, the Laser Interferometer Gravitational-Wave Observatory (LIGO) detected gravitational waves generated from merging black holes for the first time in human history. Through an engaging, easily accessible approach, the origins, dynamics, and ultimate fate of black holes are thoroughly unraveled so that students without a scientific background can grasp complex physics theories. This book supports the Next Generation Science Standards' emphasis on scientific collection and analysis of data and evidence-based theories by discussing the methods research universities and space agencies use to explore black holes.
Supernovas Explained
This engaging volume guides readers into the hearts of massive stars on a journey toward understanding one of the universe's most fascinating occurrences, a supernova event that signifies the end of a star's life. By exploring the origins of star formation and stellar evolutionary paths, students will come to understand the conditions that lead to the explosive deaths of massive stars, including an in-depth look at the groundbreaking detection of Supernova 1987A, the closest supernova observed in the past four hundred years. Additionally, readers will learn about the supernova research currently being conducted by universities across the world and by space agencies such as NASA.
Steamboats to Martha's Vineyard and Nantucket
The islands of Martha's Vineyard and Nantucket, off the Cape Cod coast of Massachusetts, were first inhabited by members of the Wampanoag tribe. English settlements were established in the mid-1600s. As the populations and commerce grew, so did the need for reliable transportation. The islands were first served by privately owned sailing vessels, but things began to change with the introduction of marine steam power. In 1818, the little steamer Eagle was the first to cross Nantucket Sound. Although she only remained in these waters for three months, she began what was to become a tradition of steamboat travel to the islands that lasted for 170 years. The images in this volume include well-known steamers with familiar names like Nobska, Naushon, Gay Head, and Uncatena, as well as many others.
