Fifty years ago, we sent the first astronauts to walk on the moon’s face. But what they brought back is just as important as what got them there. I’m talking about moon rocks, guys. And I got to go visit NASA’s lunar sample vault to...

Earth has seasons, but what about the rest of the planets in the solar system? Let’s take a tour from Mercury to Pluto and see what seasons would be like on all our planetary neighbors. Bring a sweater!

EVER WANTED TO WEIGH A FART? Well, it isn't easy, but Gabe from PBS Space Time walks us through the math, physics, and science behind farts and explains how to measure them!

If you take a look at all the impact craters in our solar system, the vast majority are nice, neat circles. But why? Meteorites and asteroids strike planets and moons at all sorts of angles. Where are all the elliptical craters?

In the hunt for life beyond Earth, scientists shouldn't skip over frozen planets. In some cases, ice might actually help life evolve!

Ever since we started launching stuff into space, we've communicated with spacecraft (and astronauts) using radio waves. But over the past few decades, scientists have experimented with a new technique that could make things a lot more...

Saturn's rings are younger than Saturn, and the most spectacular sight in the Solar System is also disappearing. How do we know? By running our finger through some cosmic dust.

Months before Apollo 8 took humans around the Moon for the first time, two Russian tortoises (plus some other lunar tourists) had already made it back home. This was Zond 5 — the first mission to return to Earth after visiting another...

About 1.8–0.8 billion ago, the Earth went through a period known as the Boring Billion, where not a lot changed in terms of geology, evolution, or even the number of hours in a day. Some scientists call it “the dullest period in Earth’s...

In this episode, we discuss the basic nature of gravity, one of the four fundamental forces in our universe.

One Minute Physics provides an energetic and entertaining view of old and new problems in physics -- all in one minute!

2018 was full of exciting discoveries and incredible advancements in the field of science. So today, we are taking a look back at 2018 to highlight three more great science news stories!

In 1965, MIT's Lincoln Laboratory saw their Lincoln Calibration Sphere 1 (LCS-1) launched into Earth orbit. It was an empty aluminum sphere and couldn't do any science of its own. But the world's most boring disco ball has played a huge...

The Apollo program was famous for being risky and expensive. It sent multiple daring astronauts to the moon, but had a crunched timeline, and lacked modern tech. In this special episode of SciShow, we'll be discussing... was the Apollo...

You know how moths like to fly into lamps or crawl all over your tv screen at night? Why do they do this?! The answer is more complicated than you might think...

Hank talks about astrobiology - the study of and search for life in the universe off Earth. Right now, the field has more questions than answers, but all they all seek to answer that one fundamental query: are we alone in the universe?

We often think of the ocean’s tide as a simple rise and fall, connected to the motion of the Moon. But on any given shore, the reality is much more complex and oceanic scientists have realized recently that there’s another, more...

Hank gets to the bottom of this "faster-than-the-speed-of-light-neutrino" kerfuffle, discusses some ancient stuff, and announces the winner of the award for worst science in a film.

The equator is a clear and accurate line around Earth that makes measuring latitude a precise science, but when it came to figuring out how to do that with longitude, British sailors were at a loss. Until they devised a competition....

From menstrual cycles to rainfall, there are lots of claims about the moon's influence. In today's episode, Hank is here to set the record straight with 8 myths & facts about our moon.

Hank discusses the challenges involved in manned space travel to Mars, and sends us a message from his 17-year-old self.

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?

You can complain about having the longest day ever today, and here is the science to prove it!

Let's learn all about the waves that we play in at the beach!
