Earth is truly amazing! It has giant glaciers, gorgeous canyons, and it's the only planet we know of with intelligent life. Ian is exploring Earth with his tour guide, Dr. Sally. Join them as they study ocean animals, the African savanna, and the chilly South Pole. Find out more about the planet we call home.

Have you ever wondered what it would be like to go into outer space? Soon you might be able to find out! For years, only trained astronauts were allowed to travel through space, but now lots of companies are creating spacecraft that will allow regular people to experience space for themselves. World View Enterprises wants to take people to near space using a helium balloon. And Virgin Galactic has already sold hundreds of tickets for a ride on its Unity spacecraft. But is this kind of space travel safe? Will these new spacecraft be able to get off the ground?

Did you know that Pluto has mountains, glaciers, and even blue skies? In July 2015, a spacecraft called New Horizons finally reached Pluto - almost 10 years after it had launched! The spacecraft flew by Pluto to take the first close-up photos of the dwarf planet. When it began sending those photos back to Earth, scientists were amazed by what they saw. Pluto was more fascinating than scientists ever imagined!

Have you ever dreamed of walking on Mars? Or maybe even living there? Ever since Mars was discovered, people have wondered if there could be life on this mysterious red planet. For years, astronomers at NASA and other space agencies have been exploring Mars. They've sent rovers to study the planet and search for water and signs of life. One day, NASA plans to send astronauts there, too. But first, they need to learn many things about Mars and how people might travel that deep into space.

Did you know that companies and governments send more than 100 satellites into space every year? And that most of those satellites continue to orbit Earth - even after they have stopped working? More than 500,000 old satellites, pieces of metal, and other bits of junk currently pollute Earth's orbit. And that number is growing. Astronomers, engineers, and politicians all agree that the future of space exploration is in danger if this debris isn't taken care of. But the problem of garbage in space is difficult and expensive to solve.

Did you know that astronauts work on Earth and in space to study places beyond our planet's atmosphere? But there's a lot more to space travel than just research. With no gravity, a wild schedule that includes 16 sunrises and 16 sunsets every 24 hours, and no fresh food, it can be a challenge to stay healthy in orbit. Public and private space agencies are working to solve these problems as humans travel farther and more frequently into the depths of space. Learn more about the daily lives of astronauts and how they live, work, and prepare for the future in space.

Does the universe circle around Earth? Do creatures live on the sun? Can you tell the future by looking at the stars? At one time science supported wild notions like these! But later studies proved these ideas were nonsense. Discover science's biggest mistakes and oddest assumptions about physics and astronomy, and see how scientific thought changed over time.

On April 11, 1970, astronauts Jim Lovell, Fred Haise, and Jack Swigert were launched into space as the crew of Apollo 13. Their mission, like the missions of Apollo 11 and Apollo 12, was to explore the lunar surface. But that mission was never completed. As they began the procedure for landing on the Moon, the spacecraft was rocked by a violent explosion. Oxygen began pouring out of the Service Module, and the spacecraft began to lose power. Jim Lovell radioed Mission Control with the now-famous words, "Houston, we have a problem."

John Farrell takes kids on a rhyming tour of the night sky, from A to Z, with facts about the wonders of space. From distant Andromeda, a galaxy made up of billions of stars, to the constellation of the zodiac, Farrell covers the high points of outer space. How do you find Jupiter or Venus? How does the Moon cause the tides of Earth's shores? How can you find the North Star, and why do all other stars seem to go around it? The answers to these and many other questions are contained in this beautiful volume of science that will delight a young listener's imagination.

Discover the daring aviation pioneers who made the dream of powered flight a reality, forever changing the course of history. Aviator Lincoln Beachey broke countless records: he looped-the-loop, flew upside down and in corkscrews, and was the first to pull his aircraft out of what was a...

Black holes are the most extraordinary phenomenon in the universe, but they are a riddle that confounds our intuitions. Anything that enters them can never escape and yet they contain nothing at all. They are bigger on the inside than the outside suggests. They are dark on the outside but not on the inside. They invert time into space and space into time.
