This video is about the orbital mechanics of why it's so hard to crash into the sun - the energy it takes to get there is astoundingly high, compared with leaving the solar system.

How To Go To Space (with XKCD!)

Where rivers meet the ocean, coastlines tend to bend either inward or outward, creating estuaries and deltas. But how do they get those shapes? Want to learn more about the topic in this week's video? Here are some keywords/phrases to...

Climate innovation leader Rich Powell dives into the bureaucracy, bottlenecks and not-in-my-backyard attitude preventing the US from achieving its green energy goals, warning that we need about 10,000 new clean energy projects to be...

The vast, white surface of Antarctica stretches for over 3 million square kilometers. On the coast of this expanse, just a few meters beneath the ice, lies a remarkably diverse realm that is home to over 8,000 species of sea denizens who...

Mars has a ton of amazing features waiting to be explored, but we have to get there first. Thanks to our partners at the Boston Museum Of Science for helping us think about everything we need to plan a trip! Squeaks and Jessi would love...

The body can get a whole lot colder - but not a whole lot hotter - before we die. Why is that?<br/>

We know that gravity exerts its pull on light, and we have an explanation for why. Actually, we have multiple explanations that all predict the same thing. And at first glance, these explanations seem to describe completely different...

Time passes for all of us at the same rate of one second per second. But why does it sometimes feel like time is passing so fast, or so slowly? Especially during COVID? Let’s learn about how our brains keep track of and try to make sense...

The Solution to the Windmill Paradox. This video is about the tradeoff of Windmills: the fact that the more kinetic energy you extract from the wind the slower the wind goes, the less wind you have to extract energy from, etc. How much...

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

For thousands of years, sailors have been telling stories of a mysterious phenomenon called dead water. Even after scientists figured out why it happens, it still affects swimmers today.

Did you know that a massive ancient flood triggered a thousand year ice age? 13,000 years ago, North America seemed to be thawing from a 2.6 million-year ice age. Then, a huge swath of Earth was suddenly plunged back into the cold for...

Did you know that last year we had 28 of the fastest days ever recorded? Earth's rotation can be affected by a number of things, and scientists think we might someday need an unprecedented adjustment: deleting a second!

For years, catch-and-release anglers have been pouring soda on bleeding fish in an effort to help save their lives. But.. does this actually work?

We know what the dinosaurs looked like thanks to fossils, but have you seen some of these wild creatures? Join Michael Aranda for a new episode of SciShow and take a closer look at some of the strangest-looking animals evolution has...

This episode is brought to you by the Music for Scientists album! Check out “The Idea” music video here: • The Idea, written... . Given just a little time, bacteria could outgrow earth, so what's stopping them?

It’s so easy to forgive a dog, especially when they start with those puppy dog eyes. As it turns out, those puppy dog eyes and the effect they have are no accident and the result of centuries of domestication.

Photosynthesis plays a huge role in regulating the earth's CO2. But what happens when the temperature gets high enough that photosynthesis slows down?

Flies are evasive buzzing machines that make it nearly impossible to swat. Luckily, science has some explanation to help you predict their next move. Hosted by: Stefan Chin

For many, it's a time of uncertainty and isolation. But in poet Tess and culture series, "CANVAS.""
