Astronomers have announced the Juno space probe’s first findings from Jupiter!

Jupiter is the biggest planet in our solar system. The gas giant is NOT a failed star, but a really successful planet! It has a dynamic atmosphere with belts and zones, as well as an enormous red spot that’s actually a persistent...

In this video Paul Andersen explains how biodiversity can be measured through genetic, species, or ecosystem variety on the planet. Species diversity is increased through speciation and decrease through extinction. The mechanism for...

Why do some regions experience full-time heat while others are reckoning with frigid temperatures and snow? And why are the seasons reversed in the two hemispheres? Rebecca Kaplan explains how the shape of the Earth's orbit around the...

Jessi introduces you to some of the most newly-named members of the solar system: the five dwarf planets!

Research suggests that nearly every star has at least one planet, but we haven't found any other solar systems that look quite like ours.

The largest planet in our solar system is no stranger to throwing its weight around, both to our benefit and detriment here on Earth.

In this brief talk from TED U 2009, Jonathan Drori encourages us to save biodiversity -- one seed at a time. Reminding us that plants support human life, he shares the vision of the Millennium Seed Bank, which has stored over 3 billion...

Saturn is the crown jewel of the solar system, beautiful and fascinating. It is a gas giant, and has a broad set of rings made of ice particles. Moons create gaps in the rings via their gravity. Saturn has dozens of moons, including...

In this video Paul Andersen explains in more detail the history of the Earth. He shows how the history of the Earth is written in the rocks that are built up over time. Fossils allow us to compare different rock layers relative to one...

Researchers think a planet-wide groundwater system may have once existed on Mars, and SpaceX launched the very first commercial crew capsule which docked on the International Space Station!

In this video Paul Andersen explains how rock is formed and changed on the planet. The video begins with a brief description of rocks, minerals, and the rock cycle. Plate tectonics is used to describe structure near plate boundaries. ...

What does the world look like when you map it using data? Social geographer Danny Dorling invites us to see the world anew, with his captivating and insightful maps that show earth as it truly is -- a connected, ever-changing and...

Astronomers still aren't sure about how our solar system might have formed, but they have simulations to help them get closer to the answer!

Or why we live on an onion made of magma

Hank tells us the story of bunny and planet Wonderful, and the impacts of exotic invasive species on ecosystems while introducing us to a couple interesting individuals.

Fomalhaut is a massive young star surrounded by a ring of dust debris that can tell us a great deal about the formation of our own solar system.

Earth had a climate long before we showed up and started noticing it and it's influenced by a whole series of cycles that have been churning along for hundreds of millions of years. In most cases those cycles will continue long after...

So we have Weather and Climate... but are they the same thing? No, no they are not. But they are both super important to how the geosphere is shaped. In this episode of Crash Course Kids, Sabrina chats with us about the differences...

Chat with a friend about an established scientific theory, and she might reply, "Well, that's just a theory." But a conversation about an established scientific law rarely ends with "Well, that's just a law." Why is that? What is the...

Have you tried to dig a deep hole? So deep that you could dig all the way to the other side of the Earth? It's pretty hard, and lots of people have tried. So what's stopping us from digging through the Earth? It has something to do with...

Let's say you're looking for a specific constellation in the sky, but can't find it? That could be because you're on the wrong part of the planet to see it. In this episode of Crash Course Kids, Sabrina talks about how the Earth's...

Paul Andersen describes the macromolecules that make up living organisms. He starts with a brief description of organic chemistry and the importance of functional groups. He also covers both dehydration and hydrolysis in...

In this video Paul Andersen explains the vital role that water plays in the processes on the Earth's surface. Water has several unique properties including high heat capacity, transparency, polarity and the ability to change the...
