black holes (astronomy)

"On-point historical photographs combined with strong narration bring the story of the first photograph of a black hole to life. Kids will learn why it was so hard to take a photo of something so dark it does not reflect light, and so far away it could barely be reached. Primary source quotations bring the amazing accomplishment to life"--.

What is a black hole? What is dark matter and what is it made of? How do scientists discover black holes and dark matter if they can't be seen? What do scientists know about these mysterious parts of the universe and what do they still hope to find out? Budding astronomers will learn the answers to these questions and more.

Describes the physical characteristics and life cycles of the stars and discusses how they form and release the various gases and minerals that make life on earth possible.

Explores black holes, discussing what they are, the different types of black holes, who first studied them and more.

"An astronomer answers questions on the cutting edge of astrophysics to explore the science of black holes and their role in theoretical physics, from Einstein's equations of general relativity to testing string theory"--OCLC.

"Nothing in space captures our imaginations like black holes. But the truth is no human had ever seen a black hole before. No one. Ever. The challenge was immense. The goal was impossible. Astronomers would need a telescope as big as the Earth itself. The technology simply didn't exist. And yet, on April 10, 2019, the Event Horizon Telescope team gave the world its first real look at a black hole"--Back cover.

"Black holes are neither holes nor black. In fact, they're invisible and packed with matter! . . . text breaks down the most important information about black holes, such as how scientists locate them and their significance in a star's life cycle"--Provided by publisher.

"Readers curious about space will [find out] what astronomers currently know about black holes, and will learn about some of the mysteries we have yet to solve"--Provided by publisher.

"In science fiction, time machines let people travel backward in history and forward to the future. How could one of these time-traveling devices be created? Scientists have some ideas, which include using spaceships and black holes. Discover the science and technology behind what it would take to make a real-life time machine!"--Provided by publisher.
