What if saving lives and growing a company went hand in hand? Public health expert Myriam Sidibe thinks many businesses are going about social impact all wrong — and leaving millions of dollars on the table at the same time. Drawing from...

New tech spawns new anxieties, says scientist and philosopher Grady Booch, but we don't need to be afraid an all-powerful, unfeeling AI. Booch allays our worst (sci-fi induced) fears about superintelligent computers by explaining how...

In 2023, Joseph Dituri set a world record for the longest continuous stay underwater. And that 100 day stay had effects on both his body and mind. Scientists have been studying the effects of living underwater since the 1960s, but how...

No one likes being sick, but can you imagine catching a bug while hurling through space? Turns out, this is an issue that many space agencies have worked to study and mitigate. <b<br/>r/>

Right now, discarded parts from old spacecraft, bags of pee, and dead probes are just floating around in space, but it doesn’t have to be like that. Let's take a look at some of the ways we've figured out to reduce, reuse, and recycle in...

It's always an asteroid heading straight toward us that we worry about, never what happens to us when we head straight toward the asteroid. OSIRIS-REx's experience with Bennu tells us it's worth a thought.

It’s common knowledge that you should never look directly at the sun. But, like, what about during an eclipse? Surely you can look then?

We’ve talked a lot about black holes, but there are other kinds of space holes out there that deserve some time in the spotlight!

After we retrieved samples of the moon, it was quite a while before we could land on anything else and bring bits of it back home.<br/>

Many space missions take billions of dollars and decades of work to get develop, but 25 years ago this spacecraft delivered stunning results on a shoestring budget and a minimal development timeline.

Surveyor 6 may not have been the first craft to make a soft landing on the Moon, but it is the first craft to take off from the surface of another world. And it did so in a very adorable way. Long before any Apollo astronaut, Surveyor 6...

Humans have been hurling spacecraft at the Moon for over 60 years. But even with all that practice, it's still quite the challenge to successfully land something on the surface. Case in point: in August 2023, two missions attempted to...

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...

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

We’re all excited about the Mars rover Perseverance this week, but scientists are also working on some other exciting things!

Hank tells us three things we probably didn't know about the Voyager 1 spacecraft.

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...

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

Earth’s magnetic field is special! And, in the last 20 years, we’ve made incredible discoveries, thanks to a squad of probes that have flown around our planet, observing solar wind as a team!

The Apollo 11 moon landing was about the astronauts, mission control, software and hardware all working together as a seamless integrated system. None of which would have been possible without the contributions of one engineer: Margaret...

The combined market capitalization of Amazon, Apple, Facebook and Google is now equivalent to the GDP of India. How did these four companies come to infiltrate our lives so completely? In a spectacular rant, Scott Galloway shares...

Today, Clint Smith is teaching you about the Civil Rights activist and Icon, Reverend Jesse Jackson. Jackson began his career working with Martin Luther King in the 1960s, and in the 1970s he founded PUSH, an organization to advance the...

The Astrophysics Pioneers program is funding four innovative new missions that read like a best-hits album of the most exciting astronomical frontiers: from galaxy evolution and exoplanets, to neutron star mergers and astroparticle physics.

Francis Ford Coppola's "Apocalypse Now" is a different kind of war movie. It's a multi-genre film that maybe says more about human psychology than it does about war. In this episode of Crash Course Film Criticism, Michael Aranda takes us...
