Get Ready for a New Star in the Night Sky! | SciShow News

{♫Intro♫} Stars explode and die all the time, but they’re so faint and far away that on Earth, we rarely notice. Dying stars we can see with the naked eye are few and far between. Luckily for us, though, three astronomers announced at the American Astronomical Society meeting last week that in not too long, […]

The How, Why, and How Much of Oil

This is a barrel of crude oil. It holds about 42 U.S. gallons or about 159 liters. Each day, the world consumes 88 million of them. 19 million of which are used right here in the U.S. of A. For 150 years now, we’ve been living in a petroleum world. Most experts agree… …that over […]

Environmental Econ: Crash Course Economics #22

Adriene: Welcome to Crash Course Economics. I’m Adriene Hill Jacob: And I’m Jacob Clifford. Economics is about choices, and how we use our scarce resources. It’s not just about producing and consuming, it can also be about conserving. Adriene: Maybe counterintuitively, economics has a lot to add to discussions of how we can balance our […]

Electric Current: Crash Course Physics #28

Imagine you’re floating down a river. Maybe the stream is calm and serene, flowing without obstruction. Or perhaps it’s a rushing river, churning and splashing over rocks! Well, the way water moves in a river is a lot like how electricity flows through a wire. But when we say that electricity is flowing, we’re really […]

Electric Charge: Crash Course Physics #25

The shock you get from a doorknob. That trick you used to do with a balloon, to make your hair stick up. Or, of course, a lightning strike. They’re all governed by the same principle: static electricity. Static electricity occurs when an object obtains a net amount of positive or negative electric charge, creating an […]

Electricity: Crash Course History of Science #27

Like thermodynamics, the history of electrical physics has its roots in pre-industrial questions that converged in the nineteenth century. These questions became a research paradigm, driven by a whole crew of researchers… And they led to a power system that reshaped the world. Time to get tingly! [Intro Music Plays] The study of electricity goes […]

What if Earth Was Hit by a Giant Solar Flare?

[♪ INTRO] Every now and then, you’ll hear a story on the news about a new solar storm. They happen all the time, but they’re usually not intense enough to affect Earth beyond some neat light shows around the poles. But sometimes, they can be really powerful, and they have the potential to wreak all […]

First Results from the Probe That Went to the Sun

[♪ INTRO] The Sun is a pretty big deal. It affects pretty much everything that happens here on Earth as well as all the other planets in the solar system. But in some ways, we know shockingly little about what the Sun is actually like. Now, that’s about to change, thanks to the first results […]

We’ve Never Seen a Pulsar Explode Like This | SciShow News

[♪ INTRO] Human space exploration is all the rage these days, with NASA and other organizations racing to get astronauts on the Moon and beyond. But one UK-based startup is dreaming of something a little different. They want to populate the Moon with robots. And instead of building a traditional, multi-wheeled rover, they’re designing ones […]

The Future of CubeSat Propulsion

[♪ INTRO] In the world of spacecraft, every gram costs money, so if you want the cheapest ship, you’ve got to build the smallest ship. That’s the promise of CubeSats: tiny satellites at bargain-basement prices. The smallest measure just ten centimeters on a side, roughly the size of a Rubik’s cube, and weigh a little […]
