The James Webb Space Telescope has launched! But it was a very long road to get to this point, and we’ve been following the progress for a decade!

We here at SciShow compiled a list of videos based on popular requests. Hank Green hosts with this winter themed episode!

Raindrops and snowflakes generally start to form around something else in the air, like a speck of dust, but sometimes that something else is bacteria.

In which John Green teaches you about the Little Ice Age. The Little Ice Age was a period of global cooling that occurred from the 13th to the 19th centuries. This cooling was likely caused by a number of factors, including unusual solar...

If you've ever gone outside really early on a cold day in fall, you might have seen a thin layer of sparkly ice crystals covering everything! That ice is called frost, and it can only form if the weather is exactly...

The cold medicine you picked up at the store involves some cool chemistry to treat your symptoms.

In this video Paul Andersen attempts to explain the age old questions - What is Energy? Even though it comes in many forms one of the defining characteristics of energy is that it is conserved over time. He then explains that all...

Can Humans Really Feel Temperature

This video is about how we don't just need energy to power our lives, we need *low entropy* energy! Thanks to Google Making and Science for supporting this series, and to Sean Carroll for collaborating on it!...

Frozen water molecules don’t seem to be all that interesting. But, these eight weird things that ice can do are truly mind-boggling.

Black holes are among the most destructive objects in the universe. Anything that gets too close to a black hole, be it an asteroid, planet, or star, risks being torn apart by its extreme gravitational field. By some accounts, the...

The snow is really coming down where Jessi lives, so she and Squeaks decided to stay indoors where it's nice and warm and look back on some of the amazing things they've learned about winter! Grab a fuzzy sweater and a mug of cocoa and...

Bananas! They've got a long trip from harvest to table, and a lot of science goes into keeping them delicious

Somewhere between "boiling lava" and "the surface of Pluto" is the perfect shower temperature, but why is it so elusive?

Devices that collect data about our bodies need power, but they also might need to be very small or even ingestible. To avoid including batteries in these cases, researchers are looking for ways to harvest energy from the body itself.

In this video Paul Andersen shows conceptual thinking in a mini-lesson on describing scale.

With their squishy bodies and color-changing abilities, octopuses and other cephalopods already look like our planet’s resident aliens. But researchers have discovered yet another thing that separates them from most other animals on Earth!

Scientists have discovered an underground lake of liquid water on Mars! While this isn’t itself evidence for life on Mars, it does raise some new possibilities.

Animals have all kinds of adaptations to help them get through winter, from hibernation to boots and hats. But trees have to make it through the coldest months of the year alive, too, and they've developed some pretty extreme ways to do it!

Marine archeologists accidentally found the world’s oldest known intact shipwreck, and their work scanning, diving, and exploring has given us some very cool insights into more than just our history sailing the oceans.

Sensory deprivation tanks, oxygen therapy chambers and unbelievably cold saunas - oh my! These machines are used to reduce stress, ease pain and could be useful in doing that, but these machines are generally meant to be used in very...

As if you needed any more proof that alcohol just makes weird stuff happen, Quick Questions explains why alcohol can make you /feel/ warm, when it's actually making your body colder. You'll never think of brandy the same way again!

Have you ever seen an airplane high in the sky leave a long trail behind it? That's called a contrail! It's kind of like a cloud, or your breath on a cold day. Jessi and Squeaks explain the special circumstances that make contrails happen!

Winter is upon us, and for many that includes snow! And although snowflakes are ice crystals that become flakes under the right conditions, they also have mysteries that can be less simple to explain!
