More than a billion years ago, two black holes in a distant galaxy locked into a spiral, falling inexorably toward each other, and collided. "All that energy was pumped into the fabric of time and space itself," says theoretical...

emily Parsons-Lord re-creates air from distinct moments in earth's history -- from the clean, fresh-tasting air of the Carboniferous period to the soda-water air of the Great Dying to the heavy, toxic air of the future we're creating. By...

Humans are great at understanding medium-sized things, like how far the supermarket is from your house, or how to find the bathroom in the dark. But imagining distances in light-years is a lot harder -- so you'll have to use a trick or two.

A private company has been approved to land on the moon!

Astronomers might have finally discovered part of why Tabby's Star acts so strangely and we have some new ideas about what triggers a type Ia supernova.

Theoretically, we could hide the Earth from faraway telescopes, using a properly placed laser pointer.

How to Find an Exoplanet

There’s probably life somewhere besides Earth, but all the exoplanets are so far away we may never see their surfaces in detail or intercept a clear radio signal from them. How do we determine if a distant planet has life?

Shortly after Jupiter formed, it might have been struck by an object that may have otherwise become its own planet! And researchers have a new estimate of how many Earth-like planets might exist.

2019 will be a big year for the moon! Not only is it the 50th anniversary of the first moon landing, but our closest neighbor is receiving a bunch of new visitors this year.

What would it take to settle Mars? In a talk about the future of space exploration, Lynn Rothschild reviews the immense challenges to living elsewhere in the universe and proposes some bold, creative solutions to making a home off planet...

Space physicist Miho Janvier studies solar storms: giant clouds of particles that escape from the Sun and can disrupt life on Earth (while also producing amazing auroras). How do you study the atmosphere on the Sun, which burns at...

They predate the dinosaurs and they outnumber us by trillions, yet you might not ever have the pleasure of seeing one. So let us introduce to you, the nematode.

Certain cognitive biases cause humans to make unsafe decisions in a pandemic, making a terrible disease even worse.

SciShow News looks at some of the firsts, highests, and lowests of the year in science.

Neil deGrasse Tyson was asked by the Templeton Foundation to answer the question "Does the Universe Have a Purpose". Then he read his answer aloud and I drew some pictures for it.

Climate change is real, case closed. But there's still a lot we don't understand about it, and the more we know the better chance we have to slow it down. One still-unknown factor: How might clouds play a part? There's a small hope that...

Plants are amazing. Really! Photosynthesis is an incredible thing. But it also means that some plants can't live everywhere. They need to get the right amount of sunlight for the right amount of time. In this episode of Crash Course...

At the center of a galaxy more than 55 million light-years away, there's a supermassive black hole with the mass of several billion suns. And now, for the first time ever, we can see it. Astrophysicist Sheperd Doeleman, head of the Event...

Just now, somewhere in the universe, a star exploded. In fact, a supernova occurs every second or so in the observable universe. Yet, we’ve never actually been able to watch a supernova in its first violent moments. Is early detection...

Product designer Eben Bayer reveals his recipe for a new, fungus-based packaging material that protects fragile stuff like furniture, plasma screens -- and the environment.

You may not know it yet, but AJ Jacobs is probably your cousin (many, many times removed). Using genealogy websites, he's been following the unexpected links that make us all, however distantly, related. His goal: to throw the world's...

Is there life beyond earth? Join NASA's director of planetary science James Green for a survey of the places in our solar system that are most likely to harbor alien life.

At the heart of the Milky Way, there's a supermassive black hole that feeds off a spinning disk of hot gas, sucking up anything that ventures too close -- even light. We can't see it, but its event horizon casts a shadow, and an image of...
