So, have you ever wondered why we have seasons? Or maybe where the sun goes when it's night time? *Hint: It doesn't actually go anywhere* In this episode of Crash Course Kids, Sabrina talks about the Earth's rotation and revolution and...

In November 2023, NASA's Lucy spacecraft flew by the asteroid Dinkinesh and made a startling discovery: not only does this small asteroid have an even smaller companion (named Selam), that companion is shaped like a two-tier snowman....

If the earth is spinning to the east at 1000 miles per hour... why can't we fly west more easily?

Why is the Solar System Flat?

Is it in the Arctic Ocean? In Canada? Russia?

An oblate spheroid is a special case of an ellipsoid where two of the semi-principal axes are the same size.

Learn the about the physics that allows bikes to stay upright and in motion, even without a rider.

Thomas Edison often gets credit for the invention of the light bulb, but a good argument can be made that they were around centuries earlier in the form of barometric light. <br/>

In the 1970s, astronomers discovered a mysterious source of gamma rays that, 50 years later, still hasn’t revealed all of its secrets.

Neutron stars, are some of the most extreme phenomenon in the universe. It's doubly so for a subset known as pulsars. Some are spinning so fast, and are so massive, that astronomers aren't entirely sure how they got to be that way. One...

Astrophysicists have discovered a black hole that for millions of years has been blasting vast particle beams in opposite directions across the sky. And has recently swiveled to point its one of these jets directly at us. Is this an...

This video is about the physics of geosynchronous and geostationary orbits, why they exist, when they don't, when they're useful for communication/satellite TV, etc.

One Minute Physics provides an energetic and entertaining view of old and new problems in physics -- all in one minute!

In 1965, MIT's Lincoln Laboratory saw their Lincoln Calibration Sphere 1 (LCS-1) launched into Earth orbit. It was an empty aluminum sphere and couldn't do any science of its own. But the world's most boring disco ball has played a huge...

How different would things be if Earth had always rotated in the opposite direction? Hosted by: Stefan Chin

While there is a little wiggle room, the planets in our solar system really are orbiting on mostly the same level. Why do they do that?

This week, Mister Brown joins Squeaks to answer a bunch more of your questions about the Earth and about our bodies!

Why is the Solar System Flat?

Quantum physics is weird. But quantum computing could be awesome! Learn how scientists took a big leap this week toward making quantum computers a reality.

Sending rockets into space requires sacrificing expensive equipment, burning massive amounts of fuel, and risking potential catastrophe. So in the space race of the 21st century, some engineers are abandoning rockets for something more...

Since the days of Ancient Greece, philosophers and scientists have been wondering: What is space? Is the absence of things.... a thing? These questions continued to fascinate physicists in the modern era, leading Isaac Newton, Ernst...

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...

The energy in the universe never increases or decreases -- but it does move around a lot. Energy can be potential (like a stretched-out rubber band waiting to snap) or kinetic (like the molecules that vibrate within any substance). And...
