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?

Do you know that astronauts are not the only living beings who can travel through space? Our human microbes do as well! When human astronauts go into space and return, they bring the microbes inside their bodies with them! Learn what these organisms teach scientists and how they can affect the human body both in space and on Earth.

Take a ride on a rover with NASA as they explore the planet Mars. Learn how NASA explores Mars for evidence of life especially the existence of water. Scientists believe that life depends on water. Is it possible that Mars had life and why is it so different from Earth? Discover the tools, equipment and methods scientists use to uncover rock, water, and fossils to test as evidence of life.

Did you hear? Pluto is not considered to be a planet anymore—but don’t worry, astronomists used scientific evidence to prove Pluto's demotion. Learn about the scientific method and how it allows scientists to reevaluate theories as new evidence emerges. What do you think Pluto should be classified as? Planet or Dwarf Planet?

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!

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.

Das Universum ist voll mit Sternen, Galaxien, Planeten und jeder Menge anderer cooler Dinge. Jedes davon hat seine Geschichten und die Sternengeschichten erzählen sie.Sternenstaub, Perseushaufen, Killersatelliten, Schwarze Löcher, Weiße Zwerge ... In über 600 Folgen hat der Physiker Florian Freistetter in einem der erfolgreichsten deutschsprachigen Podcasts die Phänomene des Alls in Sternengeschichten verwandelt und sie verständlich und spannend erklärt.

Tensions continue to rise between the Soviet Union and the United States as they engage in a Cold War. One of these battles was the space race. Learn how both countries began engineering and scientific effort to be the first to travel into space and back to Earth and the technology necessary to operate in it. See how scientists fight for peace as they begin their efforts to explore the unknown.

"Houston, We have a problem"! During the Apollo 11 moon landing, as many as 400,000 people had jobs that were essential to the successful mission. Learn about aeronautics and the different jobs in the field that helped man take the first steps on the moon and expand our understanding of the solar system. Who was one of the first women to work at NASA and what role did she have?

An article that describes the Apollo 11 Moon landing mission in July 1969.

A little boy is out for a walk meets a new friend, the Sun! The sun tells the little boy about himself and all of the important things he does for Earth. Did you know that the sun is a star? Explore space with the sun as he tells you about why we have night and day!

Have you ever wondered why the days are so long in the summer and short in the winter? Or why we have hot weather and colder weather? Read on to learn about the Earth, how it spins around the Sun, and the seasons!

When it’s your birthday, you add one Earth year to your age. Have you ever wondered how old you would be in Saturn years? What about Mars? Read on to learn about the planets of our solar system and how long it takes for them to complete one whole orbit.

Many things look very different seen up close. To us, the sun is a giant ball of light in the sky, but to other solar systems, it might look like just another star! Those tiny lights you see in the night sky are what our sun might look like from another planet far out in space. The sun gives light and energy to our entire solar system, and is necessary for many other things. Can you name them all?

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.
