The first discovery of extraterrestrial life will almost certainly NOT be when it visits us, nor when we visit it. It won’t be when we see it’s stray TV signals. It’ll be in the excruciatingly faint changes in the color of alien sunsets...

If you rank the most habitable places in our solar system Venus lands pretty low, with surface temperatures hot enough to melt lead and sulphuric acid rain. And yet it may have just jumped to the front of the pack. In fact, we may have...

If you picture a rocket launch, do you imagine it taking off from a hot air balloon? In this episode, we'll learn how using balloons to launch sounding rockets advanced our understanding of planet Earth, radiation, and how to keep...

So what exactly do magnetic fields actually do? What would happen if they went away? Turns out, it could be catastrophic! SciShow will explain it all in this fun new episode hosted by Michael Aranda!

Our planet is full of beautiful places, but it’s also full of wonderfully weird places. We've put together some of our favorite episodes about our planet’s weirdest lakes!

Chlorofluorocarbons, or CFCs, seemed too good to be true when they were first created, and before long astronomers studying Venus' atmosphere discovered what could go wrong with this "miracle molecule."

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

SciShow Space News gives you a whiff of comet 67P, and takes you through a record-breaking skydive from an altitude five times the height of Mount Everest.

Solar storms are really common, but occasionally they can be huge, causing more than pretty light shows in the auroras. What would happen nowadays if we had a massive solar storm?

Environmental scientist David Keith proposes a cheap, effective, shocking means to address climate change: What if we injected a huge cloud of ash into the atmosphere to deflect sunlight and heat?

A launch window that only happens every 26 months means it’s the perfect time to head to Mars! The United Arab Emirates, China, and the United States all took advantage of this excellent timing.

Build your own cloud chamber particle detector and test relativity at home!

You’ve probably heard a lot about how climate change is affecting our planet, but did you know a warming climate also affects objects in space?

This video is about how terrestrial muons are part of our experimental proof of time dilation, length contraction, and special relativity in general.
