We’ve created simulations to recreate the difference in time it takes for the Sun’s equator and poles to complete rotations, and the way we’ve solved is a bit surprising. And it looks like the Milky Way may not be great at mixing metals,...

Learn about the Earth's moon -- the closest planetary body to our planet -- with this Space Science song by KLT!

This video examines the force of gravity and looks at its critical role in the formation of the sun and planets of our solar system.

For the first time in history, there is a rover on the far side of the moon and the Chang’e 4 mission is just beginning to explore this hidden side. How Close Are We to Completely Mapping the Ocean? -'https://youtu.be/KoOxTV3QIrM'...

Unreachable by man, scientists have developed a complex experiment to demonstrate the heat and pressure at the centre of the Earth. Earth Science - Geology - Learning Points. The Earth's core is a dense ball of iron and nickel. To...

Today, we're going to talk about how the Earth moves, but to do that, we're going to have to go way back to the early days of the galaxy! Processes that happened before the Earth even formed have led us to the geographic patterns and...

Australia will perpetually encounter the season opposite to the one we in the northern hemisphere will encounter, so does this means that Australia will never get a white Christmas?

Tidal Locking - Why Do We Only See One Side of the Moon

One of the most important things we have learned about the Moon is that while it revolves around the Earth, it always points the same face toward our planet. That is the only face we see when we look at the Moon from home. In fact, we...

The dark side of the Moon remained a mystery until space travel allowed for circumnavigation. What did the astronauts find? Physics - Our Solar System - Learning Points. The Moon orbits around the Earth and spins on its axis. These...

Escape velocity is defined and illustrated. The escape velocity of planet Earth is derived.

The rotation of the planet around its axis can be generally of two types: prograde and retrograde. Prograde rotation indicates that the motion is in the same direction as the Sun’s rotation—which is counter-clockwise—if you’re looking...

An increase in Earth’s rotational speed could have various impacts on life: ranging from increased earthquakes and tsunamis to a shortening of the length of the day. People could be floating in central Africa while the polar ice might...

December has the longest solar days (noon-to-noon) because of the weird way a combination of the axial tilt of the earth and the eccentricity of its elliptical orbit conspire in December. Perihelion + Solstices = Long Days.

It's Kids Academy, and welcome back to our channel! Our Sun, the most important star in our sky. All living things on the Earth depend on the sun to warm the earth, provide light during the day, and for changing seasons and differing...

Are aliens real? If so, Are aliens living among us? Do aliens exist? Are ufos real? Could a large alien ship be “hiding” somewhere in outer space, undetected by us? Let’s say they had some kind of cloaking technology,...

Euler's formula, e^{pi i} = -1, is one of the most famous expressions in math, but why on earth is this true? A few perspectives from the field of group theory can make this formula a bit more intuitive.

This is a map of the multiverse. Or in physics-ese, it’s the maximally extended Penrose diagram of a Kerr spacetime. And in english: when you solve Einstein’s equations of general relativity for a rotating black hole, the universe does...

In this video, we learn about the rotation and revolution of Earth. We discover that Earth is constantly rotating on its axis while also revolving. We also explore the concept of leap years.



This video is part of the 8-part...

In this video, we explore the question of whether the sun is moving or if it's the Earth that is moving. We also discover that the Earth's rotation on its axis is what causes day and night, while its orbit around the sun explains the...

Understanding and tracking time is key to keeping society -- and our lives -- running smoothly. Early civilizations developed calendars with just 300 days in a year. But by 1582, the time it takes for Earth to rotate around the sun was...
