Now that we’ve finished our tour of the planets, we’re headed back to the asteroid belt. Asteroids are chunks of rock, metal, or both that were once part of smallish planets but were destroyed after collisions. Most orbit the Sun between...

Giant disks around baby stars filled with gas and dust provide the material to make all sorts of planets, and new evidence proves that our solar system’s had a massive gap in it! And the water vapor in Jupiter’s moon, Europa, might not...

FEED ME! In this episode of Crash Course Kids, Sabrina has a chat with us about what living things eat to get energy. What makes something an omnivore, or a carnivore, or an herbivore? And how do plants fit in to all of this? This first...

On Aug. 12, 2018 the Parker Solar Probe started its journey to the sun and New Horizons is looking at a mysterious glow at the edge of the solar system.

Neutrinos are weird. But all the big unsolved problems in physics are somehow connected to one unsolved mystery: Why do neutrinos have mass?

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,...

Sometimes science news is less about stuff that actually happened, as much as it is about people going "PAY ATTENTION TO ME" and space news is no exception. In fact this week there was probably as much hype as real news, all in the name...

The average global temperature is on the rise, evidenced by the ten warmest years on record happening since 2005. But this isn’t just about greenhouse gases preventing heat from escaping. Another culprit comes in the form of…clouds.

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?

Thunder is not something you normally associate with a winter storm. However, if the conditions are right, you might experience thundersnow.

Not all of the naturally occurring elements were discovered here on Earth. Helium was discovered by examining sunlight, and that same technique is now teaching us about the composition of distant galaxies.

It finally happened! The James Webb Space Telescope is on its way to capturing never-before-seen images of the universe! But now that it’s airborne and unfurled, what are its next steps before it can deliver the goods?

In this episode of SciShow Kids, Jessi talks about solar eclipses, and in particular, the solar eclipse of 2015! Jessi will show you how eclipses occur and where the best places to view the eclipse are.

Here on Earth, we’re used to seeing both lunar and solar eclipses. But further out are eclipses that don’t behave at all the way we expected them to.

Sam the Bat noticed that some stars are different colors, so Mister Brown teaches him about what colors stars can be, and what all the colors mean! Next Generation Science Standards Crosscutting Concepts: Patterns: Observed patterns in...

It's spring where Jessi and Squeaks live, and with the spring comes a really cool part of our planet's journey around the sun: the spring equinox!

In general, a star’s size will determine its final destiny. Some stars fizzle out, while others explode, and what seals their fate may come down to a curious, cannibalistic process happening inside their cores!

You know how you somehow end up getting smoke in your eyes wherever you stand around a bonfire? Well, it turns out that’s not a curse! It’s much more easily explained with physics. "The more protractors, the better the party." ~Hank Green

Given that Earth’s magnetic field helps protect its life-sustaining atmosphere, you might think that the stronger a planet’s magnetic field, the better. But as it turns out, some planets’ relationships with their magnetic fields are a...

Plants need sunlight to live, but they also need to block the sun's more harmful rays. Plants can't put on sunscreen or find shade, so how do they avoid getting a gnarly sunburn?

Hank talks about a sweet-tasting substance we humans just love - where it comes from, why we need it and how we could maybe stand to love it a little less.

Understanding gravity can sometimes be a bit of a balancing act, much like the fundamental laws of physics and how they inform what it is exactly that Earth orbits.

Hank puts the immense power of the sun into perspective through comparison with the most powerful nuclear bomb ever detonated.
