As we go about our daily lives, it’s easy to forget that we’re all hurtling through space at incredible speeds. Earth is constantly in motion, rotating on its axis and orbiting around the sun. In fact, we’re all living on…

Where’s the International Space Station right now? Here’s the live International Space Station tracking map, powered by the European Space Agency (ESA).
During the 1960s, as NASA prepared to send the first astronauts into space, they realized that pens don’t work in zero gravity (actually, in microgravity). As the legend goes, they then spent years and millions of taxpayer dollars to develop…
The American Veterans Center published a video featuring a conversation with Apollo 17 moonwalker Harrison Schmitt. Schmitt, the first geologist to visit the lunar surface, discusses the Apollo 17 mission (the last moon landing mission of the Apollo Program) and…
It’s a well-known fact that light slows down in water, glass, or any other transparent medium. Even more interestingly, it returns to its original speed after leaving that medium. Yes, it speeds up! But how can that happen? Why does…
E=mc² is probably the world’s most famous equation. It means “Energy equals mass times the speed of light squared.” The formula implies that a small amount of rest mass corresponds to an enormous amount of energy, which is the physics…
An interesting question: if you look up in the Earth’s sky with the naked eye, assuming you have healthy vision, how far away can you see? Could you see beyond the Milky Way galaxy, for example?
“How long is the Earth?” is an unusual question, but let’s explore a thought experiment to find an answer. Imagine cutting the Earth into Minecraft-sized 1-meter cubes and laying them in a line through space. How far would the Earth…
When you look up at the night sky in a place without light pollution, the view is magnificent: thousands of stars and the Milky Way galaxy offer a unique visual feast. But have you ever wondered how many stars you…
At what altitude can you start seeing the curvature of the Earth? Is it visible from the top of a skyscraper, a mountain peak, or a passenger plane? Can a high-altitude balloon provide a clear view, or is it something…
When a meteoroid, a rocky or metallic body from outer space, enters Earth’s atmosphere, it’s called a meteor. If it’s large enough, it can survive the atmospheric entry and reach the Earth’s surface at tremendous speeds, becoming a meteorite. But…
Why do we see only one side of the Moon? You have probably heard references to the “dark side” of the Moon – there’s even a Pink Floyd album with that name. However, there is no “dark side” of the…
