Or why we live on an onion made of magma

What exactly will happen when the sun dies?

Mr. Andersen details the history of modern atomic theory.

There are renewable energy sources here on Earth, but to meet our clean energy needs we should consider every possible option, including the Moon.

If you could pilot a spaceship into Jupiter and Saturn, would you ever hit anything solid? And what's it like in there? SciShow Space takes you on a tour of the two biggest gas giants in the solar system.

In which John Green, Hank Green, and Emily Graslie teach you about our Sun, and the formation of the planets. We're going to focus on the formation and development of the Earth, because that's where people live. You'll learn about the...

The planets in our solar system have a very specific order. But have you wondered why they have the order they do?

This video explains how nuclear fusion occurs in stars and causes them to shine.

The mass of the sun was well understood, and translates to about 10^57 atoms. This leads to a lifetime of the sun of about 20,000 years. But we know the sun is at least 4.5 billion years old. So where does the...

Stars represent a celestial battle of two opposing forces, gravity trying to collapse the star, and radiation pressure trying to explode the star. But it comes to an end close to the time that it runs out of fuel. Gravity...

The red toy car dreams of flying, but the balloons aren't enough. Helper Cars know what to do—a hot air balloon will lift it into the sky!

In chemistry, we usually talk about atoms and molecules. When we introduce the term 'element', things get a little confusing. In this video, we will cover what an element is in chemistry and give you some examples.

Vincent teams up with Jonathan, a seasoned pilot, to attempt flying with helium balloons at the Gap-Tallard aerodrome. Watch as they navigate the challenges of cluster ballooning, including inflating 54 balloons and managing flight...

Join Agathe, Jules, and the team as they embark on an experiment to see how far a helium balloon can travel. Equipped with a GPS and camera, they track the balloon's path, uncovering fascinating insights about its flight and the...

Making liquid nitrogen is hard - in fact up until 150 years ago scientists doubted whether it was even possible to liquefy nitrogen. In 1823, At the royal institution in London, Michael Faraday first produced liquid chlorine, kind of...

Covalent bonds form when atoms share electrons to complete their valence shells, creating strong and directional interactions.

This theory states that valency arises from the tendency of atoms to achieve a stable electronic configuration by gaining, losing, or sharing electrons to form bonds

Betelgeuse, Betelgeuse, Betelgeuse. Why were you dimming? Scientists may have finally come up with the answer thanks to data from Hubble.

Without a spacesuit, there is no chance of surviving in the scary cosmic void. In science fiction movies, we often see peoples heads exploding or being frozen by the apparent pressure differential or lack of heat, respectively. As long...
