Is outer space really the silent and lifeless place it's often depicted to be? Perhaps not. Astrophysicist and musician Matt Russo takes us on a journey through the cosmos, revealing the hidden rhythms and harmonies of planetary orbits....

The atoms around you have existed for billions of years -- and most originated in the flaming, gaseous core of a star. Dennis Wildfogel tells the captivating tale of these atoms' long journeys from the Big Bang to the molecules they form...

On August 21, 2017, the United States will experience its first total solar eclipse since 1979! If you're in the right place at the right time, you're in for a spectacular show!

The first stars turned all the neutral hydrogen in the universe back into ions, created a bunch of new elements, and just generally made a mess. But without them, you wouldn’t be here.

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.

The universe started with a bang -- but how will it end? With astonishing visuals, cosmologist and TED Fellow Katie Mack takes us to the theoretical end of everything, some trillions of years in the future, in a profound meditation on...

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!

Did you play with glow in the dark toys as a kid? They’re super cool, but kind of mysterious. How do they glow after all? Hank explains the phenomenon in this quick question.

Researchers found water in the atmosphere of an exoplanet about 110 light-years away, and there's another rock from interstellar space flying through our solar system!

In this video Paul Andersen explains how a rotating system will have several quantities; including torque, angular velocity, angular acceleration and angular momentum. Each of these quantities have a vector property that can be...

As we approach the end of Crash Course Astronomy, it’s time now to acknowledge that our Universe’s days are numbered. Stars will die out after a few trillion years, protons will decay and matter will dissolve after a thousand trillion...

SciShow Space takes you to the smallest star in the universe, and explains how astronomers figured out that's what it was!

Some of the most exciting phenomena in space can’t be seen from Earth because our atmosphere soaks up high-energy light. That’s why NASA built Chandra, the most powerful X-ray telescope ever launched, and the observatory has helped...

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!

As the number of _potentially habitable" planets that astronomers find continues to rise, we seem ever closer to answering the question, _Are we alone in the universe?" But should we be looking for life elsewhere? If we were to find life...

In 2013, astronomers reported that they'd found what was, at the time, the biggest thing in the known universe.

Hank tells the story of the mysterious star known as "Methuseleh," and why scientists think that it is the oldest known star in the universe.

We might be closer to figuring out how our solar system was born and NASA has two finalists for its next New Frontiers mission.

Welcome to SciShow Space! In this episode Caitlin Hofmeister will talk about Cecilia Payne-Gaposchkin, one of the most influential women in astronomy!

More than half of all the matter in the universe is out in the dark, 'empty space.' Although it's basically invisible, the intergalactic medium has a lot to tell us about the stuff we can see.

There are a lot of incredible things in space, but neutron stars are some of the most mind-blowing. From liquid plasma oceans on the surface to a possible neutron superfluid in the core — as you go deeper into a neutron star, the physics...

Submillimeter galaxies are ancient, dense, massive galaxies with up to 10 times the number of stars in the Milky Way, and for a long time, scientists couldn’t even figure out how they existed in the first place.

You're probably used to real galaxies having curves, except not all of them seem to have gotten the memo.

Why Do We Put Telescopes in Space?
