Black holes, demystified: follow along the quest to understand the history and influence of one of space science's most fascinating and confounding phenomena. Led by physicist James Trefil and astrophysicist Shobita Satyapal, this book traverses the incredible history of black holes and introduces contemporary developments and theories on still unanswered questions about the enigmatic objects. From the early work of Albert Einstein and Karl Schwarzschild to an insider look at black hole-galaxy connection research led by co-author Satyapa, the comprehensive book surveys an exciting and evolving branch of space science. Invisible to the naked eye and telescopes, black holes have mystified and entranced astronomers, scientists, and humanity for more than a century. The first image of a supermassive black hole was only unveiled in 2019, and new black holes are continually discovered. Supermassive illuminates what we know about black holes so far and what we have yet to uncover.
