You called it, and we are grateful! Hank analyzes what went wrong with our intro, which gave us the perfect opportunity to talk about the awesomeness that is the Apollo Lunar Lander!

We’ve been sitting on samples of the lunar surface for decades and, with better technology than when they were taken, we are opening them back up to take another look!

Is there life on Venus? If there is, it would have to be unlike anything we’ve ever seen! New evidence means the possibility of life there is in question, but it could also mean a few other things.

In the early 1960s, Richard Feynman was quoted as saying that Earth's center should be a day or two younger than its surface. 50 years later, scientists re-did the math.

New research looks into how snow falls on Mars, and scientists have been looking into other things falling from the sky onto planets: diamonds!

Why Raindrops Are Mathematically Impossible

This video explores the concept of measuring the hottest place on Earth, challenging the assumption that Death Valley holds the record. By discussing the limitations of traditional weather stations and highlighting the use of satellite...

Still wondering why leaves are green and not purple or even black? CHLOROPHYLL! It's how leaves work.

A summertime look at why we sweat, why we burn, and why our fingers wrinkle in the pool

You stick cookie dough into an oven, and magically, you get a plate of warm, gooey cookies. Except it's not magic; it's science. Stephanie Warren explains via basic chemistry principles how the dough spreads out, at what temperature we...

New research suggests that Venus’ patterned crust might currently be more active than we thought! Astrophysicists have also modeled the orbits of mysterious objects between Jupiter and Neptune, and found that they could have come from...

From problems with the moon, to the lumpiness of earth, sea levels aren't quite as exact as we have them figured out to be.

We’ve got some new evidence for water beneath Jupiter’s Great Red Spot, and a new model of Jupiter’s weird magnetic field.

We’ve sent more spacecraft to Mars than any other planet, but around half of the probes that have ever attempted to explore Mars have either crashed or disappeared.

Theoretical physicist David Deutsch delivers a mind-bending meditation on the "great monotony" -- the idea that nothing novel has appeared in the universe for billions of years -- and shows how humanity's capacity to create explanatory...

Humans have been talking about space colonization for quite some time, but our neighboring planets are not exactly the most hospitable places. If we are ever going to be successful, we should probably figure out where we could reasonably...

Exoplanets are being discovered in the habitable zone to sustain life as we know it. Could water be found on the closest exoplanet to us?

The Labrador Sea is also known as the ocean's lung, and there's evidence that it's in a lot of trouble.

All over the world, giant wave breaks appear because of underwater geology that supercharges their wave energy.

It takes light a zippy 8 minutes to reach Earth from the surface of the Sun. But how long does it take that same light to travel from the Sun's core to its surface? Oddly enough, the answer is many thousands of years. Sten Odenwald...

SciShow takes you inside a limnic eruption, a natural disaster that's as deadly as it is rare.

SciShow Space takes you on a tour of Mercury, the sun's closest friend, where a year is just a day and half long, and the surface holds many surprises -- like ice!

In the late 1970s, two physicists in Switzerland set out to invent a new type of microscope using quantum physics that would allow them to do something no one had ever done before: see the individual atoms in a sheet of metal.
