Where do all the metals on earth come from? They were all made by stars! In this science story, you'll discover how the fusion of atoms in dying stars in space creates enough heat and energy to make metals.

Over time, cultures from around the world have given us many different myths about our home galaxy. When you look up at the sky at night, what stories would you tell about what you see?

The Sun is our closest star. Stars produce heat, light, and do not orbit other celestial objects.

One way astronomers search for planets is by looking for the shadows they cast in front of stars.

Our sun is great at shining down light and heat on earth, but was the sun always that bright? With the help of gravity, the sun is eventually able to produce enough energy to give off light. Our sun has kept this up for four billion years and will keep shining for another five billion years!

How can the moon or sun seem to disappear right before our eyes? When the moon, the Earth, and the sun align just right in their orbits, they can cause a solar or lunar eclipse! Find out how light and shadow work together to trigger these cool events.

Beliefs about the shape of the earth have varied over the millennia, but the Ancient Greeks were able to observe that our planet is round and even Eratosthenes attempted to measure its size. It was not until explorers had fully charted the globe that most people were really able to comprehend its spherical shape.

Anna must wake up late and struggle to keep warm outside so she can watch a meteor shower.

Astronomers have discovered a distant planet that can possibly sustain life. The planet is known as Earth and is inhabited by humans! Children will enjoy seeing how aliens might imagine the shapes and colors of Earth's creatures.

هناك العديد من الدول التي تعمخل على تطويرلمشاريع تهدف الى استغلال القمر كمساحة للتعدين أي إن صح التعبير، ترى في القمر منجم عملاق غني بالمعادن.

Imagine taking a flight to the stars! Yo pretends to take a rocket into the sky to visit the stars–only he wonders if he will see the stars. Yo doesn’t want to crash into them if he can’t see them!

Have you ever wished you could go to the moon? Learn about Neil Armstrong, Edwin Aldrin, and their fellow astronauts on the Apollo 11 who took the first steps on the moon! Discover the process and challenges that NASA overcame to safely send people to the moon with engineering and physics. Understand how this historical moment affected space exploration for countries all over the world.

Could there be life forms on planetary moons such as Europa, Jupiter’s icy moon or Titian, one of Saturn’s largest moons? Although our moon is made of mostly rock, astronomers believe life may exist on other moons! Scientists know liquid water is needed to support life, and Europa has plenty of it. What other key ingredients are needed for life to exist in our solar system?

Packed with colorful illustrations and fascinating facts, this book is the perfect guide for budding astronomers and curious minds.

¡Siete insólitos destinos para quienes deseen pasar unas vacaciones de otro planeta! Una descripción detallada, original y divertida de cada uno de los planetas del Sistema Solar, que incluye información sobre las misiones espaciales que los visitaron y datos sobre los sitios web oficiales...

Have you ever heard of the Showdown at Separation Point? In 1878, astronomers, James Watson and Urbain J.J. Le Verrier, disagreed about the existence of a planet, being named Vulcan, between the sun and Mercury. During an eclipse over Wyoming with telescopes and sky maps, they were finally able to discover which astronomer was right. Who do you think won this science showdown?

Have you ever wondered what living in space would be like? Meet the Kellys who are identical twins and both astronauts for NASA. With one brother in space and the other on Earth, they are an experiment to learn how human bodies that share the same DNA are affected by living in space for a long time. What do you think NASA can learn from this twin science study?

Do you know what kinds of food astronauts eat and drink while on a space mission? Learn how NASA prepares, dries and packages different food so it lasts for the journey! Find out the different ways that astronauts cook and eat in space which has zero gravity so it doesn't float away. Discover how astronauts use a very different kind of bathroom toilet and what happens to human waste in space.

Have you heard of the spidernauts? These two special jumping spiders were sent to space for a special mission—to see how they would adapt to microgravity. Would the spiders still be able to hunt for their food for their survival or would they starve? Learn how this experiment with insects was important to understanding microgravity and its effects on the human body!

What is a space archaeologist? After decades of leaving behind old pieces of equipment orbiting in space, scientists want to clean it up. An archaeologist determines what is important to save for the history of human space exploration. Learn about new efforts to identify and even retrieve old space equipment! How should scientists determine what should be preserved or what is junk?
