In the 1600s, Isaac Newton conducted a series of experiments to better understand the lights and colors that sometimes appear when your eyes are closed. If you’ve ever sat around an evening campfire or unintentionally glanced at the Sun,...

Have you ever wondered why you look up and see a dark sky at night?

The universe is expanding – this we know from looking at red shifts of distant galaxies – but the acceleration of the universe's expansion is harder to measure. It requires measuring the change of recession velocity over time, and it's...

If you've spent enough time on the internet, you may have stumbled upon the fact that sharks are older than Polaris, aka the North Star. But are they really? It turns out the truth is a little more complicated.

Why can't laptop screens be viewed outside like e-readers can? It turns out, they use very different technology. But engineers are working on closing the gap.

While doing some light reading of data from a telescope, Conny Aerts made a breakthrough that allowed her to lead the charge in the field of asteroseismology and win her the 2022 Kavli Prize in Astrophysics.

Earth and the other seven planets in our solar system have only one star: the Sun. Years ago, astronomers found the first exoplanet that had two stars. They also found one with three stars. And four. Just how many stars can one planet...

There are some startlingly black animals out there, whether they’re in the deep ocean or in the darkest corners of the rainforest. But humans have created some stunningly black substances too, using science and engineering. So who wins,...

Jewel beetles are pretty eye-catching with their glossy, bright coloration. But if you were a small creature that needed to avoid predators, you might think that eye-catching is the last thing you'd want to be. But it turns out that...

For most living things the color you see when you look at them is determined by pigments. But some of the most vivid colors we see in nature get their signature looks WITHOUT colorful molecules. How do these intense colors get their power?

You've heard of the battle of the sexes—but these 7 animal species take it pretty seriously. Join Michael Aranda for a new episode of SciShow and learn about these animals with pretty big sex-related disputes.

Some people try to attack things like evolution by natural selection and man-made climate change by saying "Oh, that's just a THEORY!" Yes, they are both theories. Stop saying it like it's a bad thing! It's time we learn the difference...

Astronomers have found a Hot Jupiter - WASP-121b - that is leaking metal, and put together a new 3D map of the Milky Way showing that our galaxy is actually a bit twisted!

Nature is full of all kinds of beautiful color, and there is plenty of weird science there too! Here's a showcase of a few of our episodes all about coloration.

When Quasars were first discovered the amount of light pouring out of such a tiny dot in space seemed impossible. A hysterical flurry of hypothesizing followed: swarms of neutron stars, alien civilizations harnessing their entire...

2016 was a lot of things, but for astronomers, it meant the discovery of some of the farthest, faintest, and youngest objects in the universe we've seen yet.

What exactly is a ‘Zombie Star,’ and how does it compare to other stars and supernovas? We’ve also learned more about how the haze over Pluto plays a role in its temperature.

What causes the Blood Moon?

We knew some stars created large amounts of calcium, but no one really ever knew how...until now! Plus, astrophysicists believe they’ve finally seen evidence of the star that created one of the most important supernovas ever!

Nick Veasey shows outsized X-ray images that reveal the otherworldly inner workings of familiar objects -- from the geometry of a wildflower to the anatomy of a Boeing 747. Producing these photos is dangerous and painstaking, but the...

Considering how massive our universe is, we know the distances to cosmic objects surprisingly well. What tools and clues do scientists use to measure distances that are so enormous they sound like made-up numbers?
