Engineering and art come together in architects' designs to create some of the most amazing and beautiful structures that have ever existed. In this book, we'll explore seven wonders of architecture, from the dizzying height of the Eiffel Tower, to the love-inspired Taj Mahal, to the heated competition that resulted in two of New York's tallest buildings. Along the way, we'll see advancements in materials, technology, and construction techniques, and we'll learn the stories of how and why these architectural achievements became important to the world.

The universe is full of space phenomena, such as dark matter, dark energy, and the beginning of the universe. Read what astronomers and space scientists have discovered about these amazing wonders-and what they have yet to learn.

From earliest times, humans have wondered about the sky above them. People looked at distant stars and wondered what they were made of. They wondered whether any other places in the universe were like Earth. At first people used simple telescopes to study the solar system-the Sun and all the planets that circle around it. Later, more powerful telescopes and high-tech machines allowed people to investigate worlds outside the solar system. In this book, we'll explore seven wonders beyond the solar system. We'll look at giant clouds of gas and dust called nebulae. Some nebulae are places where stars are born. Other nebulae are all that remains of stars that have died. Other wonders beyond the solar system include pulsing stars, giant stars, and giant clusters of stars called galaxies. We'll visit them all. And we'll explore the age-old question: Does the universe have any other planets like Earth? We'll learn about scientists who hunt for Earthlike planets and the tools they use. Finally, we'll look at the big picture-the universe itself. This vast network of stars, planets, and other objects is the biggest wonder of them all.

Uncover seven wonders of the four rocky planets. From Mercury, we'll watch the Sun appear to perform wild acrobatics. We'll also explore Venus, a planet full of puzzles and beauty. On Mars, we'll visit the tallest mountain and the deepest canyon of all the planets. This planet has hints of water that may be the key to identifying life forms on other planets.

From earliest times, humans have looked to the sky in wonder, and their wonder and curiosity fueled science. Ancient peoples built enormous temples and monuments to observe the sun and track the movement of stars. And as scientific knowledge expanded, technologies grew more sophisticated. Each development changed the way we viewed our place in the universe. But no technology changed our understanding more than the ability to launch scientific equipment-and human explorers-into space. In this book, we'll explore seven wonders of space technology. Scientists and engineers have built vehicles and equipment to explore the farthest reaches of the solar system. Orbiting satellites and telescopes have given us everything from more accurate weather reports to glimpses back to the beginning of the universe. International teams have built an orbiting space laboratory and are working on plans for human lunar settlements and missions to other planets. Learn about the people and the science behind these amazing advances in space technology.

From earliest times, humans have wondered about the sky above them and have studied all visible objects. People began to identify differences between stars and planets, and as technology advanced with telescopes and space probes, they sought deeper understanding of the millions of bits of debris rocketing through the solar system. Scientists determined that most of these objects are left over from the creation of the planets and their moons. They classified these leftovers into categories such as asteroids, comets, and meteors. In this book, we'll explore seven wonders of asteroids, comets, and meteors. Ceres is a huge mountain-sized asteroid that orbits with other asteroids between Mars and Jupiter. Other marvels include Ganymede, the largest asteroid in the group called Earthgrazers or Near-Earth Objects, and Halley's comet, a ball of ice, that passes Earth every seventy-five or so years. We'll also explore the amazing impact that space debris can have on planets and moons. The Borealis Basin, a wondrous crater more than 5,000 miles across, formed when an asteroid collided with Mars in the ancient past. Then we will travel to the far-off Kuiper belt, where as many as 200 million icy bodies orbit, and wonder at the mystery of planetlike objects, such as Pluto and Charon. Finally, we'll can experience a space wonder firsthand by standing outside on a night in August to watch the spectacular Perseid meteor shower fill the sky.

In every age, science and technology have advanced human civilization. From architecture to engineering, medicine to transportation, humans have invented extraordinary wonders. Explorers long ago and today have used technology to navigate, travel farther, and understand more about the world around them. They invented vehicles to carry people and tools to the ocean depths, high into the atmosphere, or even to other worlds. They invented scientific instruments to explore the most distant parts of the universe and the smallest bits of matter. In this book, we'll explore seven wonders of exploration technology. Scientists have developed technology that takes us to the deepest parts of the oceans. Undersea explorations give us a glimpse of a world teeming with unique life and full of wonderful natural structures. Teams of researchers and engineers have also built orbiting space telescopes and interplanetary spacecraft to explore the farthest reaches of our solar system. Back on Earth, scientists have created computers, machines, and systems for studying climate change and the subatomic world. Learn about the people and the science behind these amazing advances in exploration technology.

From earliest times, humans have wondered about the sky above them. Simple telescopes in the 1600s made possible descriptions of the wonders of Earth's Moon and the closer planets. It took the development of powerful telescopes and modern space probes to learn more about the more distant planets-Jupiter, Saturn, Uranus, and Neptune. In this book, we'll explore seven wonders of these four enormous planets-called the gas giants-and their moons. On Saturn, we'll examine its amazing rings and their properties. On Jupiter, we'll investigate the Great Red Spot-a gigantic storm about twice the size of Earth that has lasted for centuries. We'll also explore a moon of Jupiter with erupting volcanoes, a moon of Uranus covered with one of the weirdest landscapes in the solar system, a huge crater on a tiny moon of Saturn, as well as planet auroras much more spectacular than Earth's northern lights. We'll also consider how the discovery of water on Jupiter's moon Europa may mean that life is possible in other worlds.
