Our planet has a carbon problem -- if we don't start removing carbon dioxide from the atmosphere, we'll grow hotter, faster. Chemical engineer Jennifer Wilcox previews some amazing technology to scrub carbon from the air, using chemical...

In this lecture presentation, the focus is on the carbon cycle, which is an essential element continuously recycled and reused. The video gives examples of different cycles such as oxygen, nitrogen, and water before diving into the...

Upon viewing the Our Distant Neighbors video series, students will be able to do the following: Create a simple diagram of the sun and the orbital paths of each planet around the sun. Label each of the eight planets. Explain that the sun...

This is one of these questions where most feel like they should know the answer, many seem to know the answer, but then somehow everyone tells a different story. In this deep dive, we get to the bottom of why it is really cold in the...

To observe how winds move high in Earth's atmosphere, scientists sometimes release clouds of barium as tracers to track how the material corkscrews and sweeps around � but scientists have no similar technique to study the turbulent...

Biochar is a kind of charcoal that removes CO2 from the atmosphere, helping yield healthy crops and even producing abundant renewable energy in the form of electricity as it's made. This exciting climate change fighter is ready for...

In this video Paul Andersen describes the four major spheres on planet Earth. The geosphere makes up the mass of the planet and includes the major landforms. The hydrosphere is all of the water and the atmosphere is all of the gases. ...

Plastic bags are essentially indestructible, yet they're used and thrown away with reckless abandon. Most end up in the ocean, where they pollute the water and harm marine life; the rest are burned in garbage piles, where they release...

All the complexity in the universe ultimately owes its existence to one of the simplest materials possible: molecular hydrogen. And not only did this molecule play a huge role in building the universe as we know it, today, it also helps...

The welding process usually involves pretty extreme levels of heat. But it turns out that in the cold vacuum of space, metals can weld together... automatically.

With exoplanets, often we want to know if they are Earth-like and whether they might host life, but we can also learn a lot from planets that are nothing like Earth.

In which John Green teaches you about the beginnings of the American Revolution in a video titled The Seven Years War. Confusing? Maybe. John argues that the Seven Years War, which is often called the French and Indian War in the US,...

There’s big news coming out of the Sample Analysis at Mars instrument suite (SAM) on NASA’s Curiosity rover. For the first time, organic matter has definitively been detected on Mars. In addition to finding organic compounds in...

Delve into the Earth's atmosphere, a vital layer of gases enveloping the planet. Learn about its composition, layers, and crucial role in regulating temperature and protecting life on Earth.<b<br/>r/>

Earth's Materials and Systems part 4

Discover the process of creating a volumetric fog material to add a three-dimensional depth to the fog in your scene. Explore the settings and techniques required to set up volumetric fog in Unreal Engine 5, allowing you to create...

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...

What if we could grow buildings on other worlds? Researchers are looking to fungi to help us colonize the stars<br/>

The Solar Dynamics Observatory, or SDO, spacecraft was launched on Feb. 11, 2010, and began collecting science data a few months later. With two imaging instruments – the Atmospheric Imaging Assembly and the Helioseismic and...

This video discusses the importance of material recycling in ecosystems, specifically focusing on the carbon and water cycles and the process of decomposition. It explains how plants play a crucial role in the carbon cycle by removing...

Upon viewing the Our Distant Neighbors video series, students will be able to do the following: Create a simple diagram of the sun and the orbital paths of each planet around the sun. Label each of the eight planets. Explain that the sun...

Something mysterious is going on at the Sun. In defiance of all logic, its atmosphere gets much, much hotter the farther it stretches from the Sun’s blazing surface.



Temperatures in the corona — the...

Parodying the classic sea shanty "The Wellerman," “The Solar Wind: A Heliophysics Sea Shanty” illuminates one of the primary connections between...

For the first time, using NASA's Solar Terrestrial Relations Observatory, or STEREO, scientists have imaged the edge of the sun and described that transition – from which the solar wind blows. Defining the details of this...

Professor Tim Flannery investigates how seaweed is helping to save the world. From growing the foods of the future, helping clean polluted water and even combating climate change. Is it possible to farm seaweed in the open ocean to...
