Mysteries of space

"Solar and lunar eclipses have been a source of fascination since ancient times. Early cultures created myths to explain what was happening, ranging from animals eating the celestial bodies to the sun leaving the sky in anger. Today, thanks to advancements in science, we understand the principles behind these astronomical events. However, this understanding has not diminished our awe and fascination. Through engaging, age-appropriate text, augmented by informative sidebars and detailed graphic organizers, this volume introduces readers to the science behind solar and lunar eclipses"--Provided by publisher.

"For years, people have reported seeing strange objects in the sky. Sometimes these take the form of lights or vague shapes; other times, the witnesses give detailed descriptions of what they believe to be alien spacecraft. In 2022, the United States Congress stated that reports of UFOs have been growing, but these flying objects often remain unidentified. What is the truth? Supplemented with informative graphic organizers and engaging fact boxes, the age-appropriate text delves into the history of UFO sightings and their probable explanations"--Provided by publisher.

"Scientists believe that the universe is mostly made up of dark matter, a mysterious substance that is different from the ordinary matter people can touch, smell, see, and interact with. Dark matter cannot be directly observed, but it can be studied by examining its effect on ordinary matter. Simplified explanations of complex scientific concepts and . . . images will help students understand how physicists employ Kepler's laws of planetary motion, gravitational lensing, particle colliders, and other theories and tools to learn about dark matter"--Provided by publisher.

"Dark energy is a mysterious force causing the universe to expand in an accelerating manner. Although Edwin Hubble discovered observational proof of expansion in 1929, the first direct evidence for dark energy came from supernova observations in the late 1990s. Untangling complex physics theories,. . . this text explores the development and evaluation of scientific theories behind dark energy. Students will learn about the tools and methods scientists use to unravel dark energy's origins, dynamics, and effects on the universe"--Provided by publisher.

"In September of 2015, the scientific world was buzzing: gravitational waves had been detected. It was a dramatic and conclusive demonstration of Einstein's theory of general relativity--the most complex and far-reaching theory in the history of physics. Through detailed diagrams, . . . analogies, and . . . sidebars, this text cuts through the complexity and sophistication, providing an . . . introduction to the physics of waves, the implications of general relativity, and the ways in which gravitational waves can bring new understanding of the universe around us"--Provided by publisher.
