Hank pays tribute to some of the great scientific minds we lost in 2012, and then apologizes for some mistakes made in recent SciShow episodes.

In 1822, Count von Bothmer shot down a stork in Germany. However, the bird had already been impaled by a yard-long wooden spear. The stork had been speared in Africa and then flew over 2,500 km. This astonishing flight proved to be an...

Before moving on from Jupiter to Saturn, we’re going to linger for a moment on Jupiter’s moons. There are 67 known moons, and 4 huge ones that we want to explore in greater detail. Ganymede is the largest - larger, in fact, than any...

In this video Paul Andersen explains how forces on an object always require another object. An object cannot exert a force on itself. If net forces on an object are balanced the object will remain at rest or move with a constant...

Which of the following is awesome: your lunch or the Great Pyramid of Giza? Comedian Jill Shargaa sounds a hilarious call for us to save the word "awesome" for things that truly inspire awe.

Tidal Locking - Why Do We Only See One Side of the Moon

Scientists just discovered the largest explosion ever detected, and it's thanks to the collaborative efforts of scientists from all over the world.

SciShow Space takes to you a world where the night is always dark, the tides are paltry -- and the days are only 8 hours long. See how different Earth would be if there were no moon!

Have you ever wondered why, some nights, the moon looks like a big, bright circle, and some nights it looks like a little sliver? Join Jessi and Squeaks to learn about how the moon's orbit changes the way we see it here on Earth!

If you've ever wanted to get up-close and personal with the Moon, you might want to look up this Monday, because the moon will look larger and brighter than it has for decades.

If we hope to someday live on other worlds we need to figure out where we’re gonna lay our heads at “night.” But who would have thought we could use our own bodies as ingredients for our homes?!

How the night sky tricks our brains!

As small as Jupiter's moons are in comparison to the giant planet, they may actually have an important role to play in keeping each other warm, heating the moons enough to have liquid oceans!

Every year the moon’s orbit gets a little bigger and it moves just a little farther away. Should we worry about the Moon breaking free?

We’ve visited lots of places in our solar system in the last 60 years, but modern technology has made an unlikely candidate the hottest new frontier of solar system exploration: asteroids. Today, we’ll take a look at a few exciting...

The 1960s were an optimistic time for space exploration - so much so that a team designed a rocket called the Sea Dragon that was big enough to launch an entire space station from the sea in one go!

There are many types of dust with some surprising things floating around in them, from poop to bacteria. And these dusts can take an extreme toll on your health

The Deep Space Network is a special network of radio dishes for tracking and talking to spacecraft, and it contributes some cool scientific observations of its own too.

SciShow Space shares the latest developments from around the universe, including news about the first material ever collected from outside the solar system, and a backyard astronomers’ guide to two upcoming planetary conjunctions.

For astronauts, dust is no joke. On the moon and Mars, dust isn't at all like the stuff under your bed. It can be poisonous, corrosive, even made of razor-sharp glass. So future astronauts are going to need more than a dust buster to get...

Hank tells us about the planned demise of two lunar satellites that have been collecting data for NASA, and have now reached the end of their mission.

Humans have been using microbes to separate minerals from mud since the middle of the last century, so we know biomining works on earth. But how will these tiny miners work in microgravity?

The sun also causes tides on the earth, but they're only about half as strong as the moon's. When the sun & moon line up during full & new moons, tides are extra big.

The ESA is working on a 'fresh-squeezed' spacecraft that will explore Jupiter's moons, and the New Horizons team makes a case for Pluto (and many others)!
