Antimatter Explained

NIAC has awarded their first two grant winners for phase III: optical mining and 3D modeling craters, and researchers are further honing in on how to identify faraway habitable planets.

The sun is obviously a big factor in the earth's weather, but changes in the solar cycle don't always affect our climate in straightforward ways.

From gigantic planets too close to their stars, to those in unfathomably wide orbits, astronomers have discovered seemingly impossible solar systems that shouldn’t exist at all. But they do.

SciShow News gives you some wet and weird developments from around the solar system, including new insights about what liquid lurks under the surface of Titan, and a sweaty comet that's been spotted on its way toward the sun.

What happens when a star eats its planets? Find out on today's Space Time Journal Club.

Biologist Richard Dawkins makes a case for "thinking the improbable" by looking at how the human frame of reference limits our understanding of the universe.

So how do astronauts manage to pee and poop in microgravity? And what happens to all of their waste? Do you really want to know? If you do, the answers are inside!

Is it better to walk or run when it's cold out? If you run, then you have to deal with wind, wind chill, etc, but your body generates more heat. If you stay still, standing or walking slowly, you don't generate as much heat, but don't...

Oxygen levels in the Martian atmosphere are mysteriously inconsistent, and scientists don’t have a clear explanation for what’s behind the changes. Meanwhile, scientists DO have explanations for the tiger-like stripes on one of Saturn’s...

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.

Two astronauts are about to embark on the One Year Mission which can help us understand more about the long-term effects of being in space, and there is an upcoming total lunar eclipse (the shortest one this century)!

What do the first stars in the universe, dark matter, and superior siege engines have in common?

The True Science of Parallel Universes

Why is the past different from the future? Caltech physicist Sean Carroll explains how the arrow of time is not an intrinsic property of physics, but rather an emergent feature.

This video is about how life arose and what its main function or purpose in the universe seems to be. Thanks to Sean Carroll for collaborating on it! This video is about how life arose and what its main function or purpose in the...

This video is about Simpson's paradox, a statistical paradox and ecological fallacy where seemingly contradictory results are implied by a single set of data depending on how it's grouped. The paradox can arise in medical studies,...

The introduction to a series on visualizing core ideas of linear algebra.

On a cosmic scale, Mercury isn’t very far away, but it's incredibly hard to get there. Getting into orbit around it takes years of flybys in the solar system, but we're going to do it again!

These three stars can easily be seen with the naked eye, but it took some fancy telescopes for us to realize how weird they really are!

Just a few days before he died, Stephen Hawking submitted one last research paper using string theory math to talk about the multiverse.

One could say that snowflakes are simply frozen water — but if you compare a snowflake to an ice cube, you’ll notice a big difference. Why are all snowflakes six-sided? Why are none of them exactly the same? And how do we ski on them?...

Hank goes head-to-head with the Brain Scoop’s Emily Graslie to match wits about springs, hoaxes, and human evolution!

Let's look further into what we don't yet know about the Big Bang, and how the theory could progress in the future. Since there is a discrepancy between general relativity and quantum mechanics, we continue to search for a grand unifying...
