People have been exploring the oceans since prehistoric times, way before they had GPS to help them figure out where they were. Here are 6 ingenious ways our ancestors navigated the oceans.

Lots of people believe the Universe is infinite, but there's a good possibility that might not be the case. Which means that there would be an actual edge of the Universe. What happens at that edge? Is there a restaurant?

Join Phil for a tour of our capital-M Moon, from surface features, inside to the core, and back in time to theories about its formation.

Soil brings together all four spheres of physical geography, and understanding soil composition is kind of like baking! So in today's episode, we're going to show you how to create the perfect soil cake, examine its different soil...

The full moon might seem bigger on the horizon than when it's higher up, but when does it actually take up more space in the sky?

We’ve covered a lot of incredible stuff, but this week we’re talking about the weirdest objects in space: BLACK HOLES. Stellar mass black holes form when a very massive star dies, and its core collapses. The core has to be more than...

In this video Paul Andersen explains how soils are formed and classified. Weathering of rock creates particles which are mixed with water, air, and organic material. Soils are classified according to particle size, chemical makeup, and...

In this video, the importance of understanding composition in photography is discussed to effectively direct the viewer's attention and highlight key elements in a photo. The video covers various composition rules such as the rule of...

What is inside a Black Hole? A black hole is really not a celestial body like a planet or a star. There is really no substance there other than a severely curved space-time. It’a a region in space where matter is...

The Event Horizon Telescope Collaboration observed the supermassive black hole at the center of M87, finding the dark central shadow in accordance with General Relativity, further demonstrating the power of this 100 year-old theory.

The prairie landscape has come to symbolize the American heartland. But an ecosystem that once covered a vast swath of the continent has all but disappeared. Just a tiny fraction remains. But researchers and conservationists in Oklahoma...

Everything about sundogs, lunar halos, ice halos, parhelia, and circumzenithal arcs.

The incredible shining phenomenon in the highest reaches of Earth's atmosphere.

Supralateral arcs, ice pillars and sun pillars.
