In this week's news, Hank explains how earthworms are doing nanotechnology for us, Americans will soon be eating genetically modified salmon, the Russians are going back to space, and another reason to drink less soda.

Whether it's robots under the sea, wave detectors in space, or star-power on land, this episode has big experiments covered.

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!

There is some super weird, noodley stuff inside neutron stars and scientists have found evidence that black holes can have strange geometries.

This is an absolutely beautiful piece of math. It shows how certain ideas from topology, such as the mobius strip, can be used to solve a slightly softer form of an unsolved problem in geometry.

Here it is, folks: the end. In our final episode of Crash Course Astronomy, Phil gives the course a send off with a look at some of his favorite topics and the big questions that Astronomy allows us to ask.

Hank answers a SciShow viewer's most pressing question about what happens if the human body gets exposed to space. Would your head really explode?

Last week, NASA released some pretty cool Mars news: Curiosity found even more evidence to indicate the planet could’ve been habitable billions of years ago.

There is a chemical reaction discovered a century ago that could be the key to creating everything from fuel to shelter on Mars!

Margaret Wertheim leads a project to re-create the creatures of the coral reefs using a crochet technique invented by a mathematician -- celebrating the amazements of the reef, and deep-diving into the hyperbolic geometry underlying...

The formula for the cross product can feel like a mystery, or some kind of crazy coincidence. But it isn't. There is a fundamental connection between the cross product and determinants.

Trinidad's Pitch Lake is a huge, oily, and filled with millions of tons of asphalt. It may not sound like a great place to live, but the lake is teeming with microscopic life! And learning more about these organisms could give us insight...

In this fascinating conversation, cosmologist and TED Fellow Katie Mack delves into everything from the Big Bang theory to what we see at the edge of the observable universe to a few ways the cosmos might end. Stay tuned to hear Mack...

The clash of ideas is fundamental to creativity and progress, but it can also be deeply destructive and create divisions within companies, communities and families. How do you foster productive debate while protecting against harmful...

Some of the oldest galaxies we’ve ever seen are small, faint satellite galaxies orbiting the Milky Way, and they're providing us with a glimpse of how the universe evolved.

Now that we’re done with the planets, asteroid belt, and comets, we’re heading to the outskirts of the solar system. Out past Neptune are vast reservoirs of icy bodies that can become comets if they get poked into the inner solar system....

Carl Sagan predicted some amazing things including the aftermath of nuclear war.

We humans might think that flowers are pretty good gifts for a first date, but many insects have their own nuptial gifts, and well, flowers they ain't. Chapters SIX SPOT BURNET MOTHS 0:52 RED VELVET MITE 2:21 GROUND CRICKET 3:45 SCORPION...

The insides of the our gas giant friend, Saturn, might be less of a mystery now that we’ve figured out how to use its rings to indicate its internal makeup. And the light emitted from some very old, very hungry black holes could be...

Good news for fans of Venus - last week, NASA announced two new missions to learn more about our planetary neighbor! And this week, NASA's Juno mission sent back a treasure trove of data about Ganymede - the largest moon in our solar...

James Cameron rocketed onto the action film scene with 1984's "The Terminator" and followed that up with a highly anticipated sequel to the 1979 film, "Alien." His film, "Aliens," would go on to not only be a financial success, but a...

Scientists have conclusively imaged a circumplanetary disk around a distant exoplanet, and Jupiter's auroras claim the spotlight with their unique Birkeland currents.
