In his lab, Martin Hanczyc makes "protocells," experimental blobs of chemicals that behave like living cells. His work demonstrates how life might have first occurred on Earth ... and perhaps elsewhere too.

If you have an old, well-used whiteboard in your classroom, you might see something a little strange -- ghosts! But not the spooky, bust-able kind... these are the ghosts of lectures past!

Good news for fans of Venus - last week, NASA announced two new missions to learn more about our planetary neighbor! And this week, NASA's Juno mission sent back a treasure trove of data about Ganymede - the largest moon in our solar...

After observing what we thought was just a big asteroid in the asteroid belt, a team of astronomers now thinks this might qualify as a dwarf planet. And scientists had the chance to directly observe the collision of two neutron stars for...

Earlier this spring NASA announced a new research model that predicts that ocean worlds are far from rare, and our galaxy might be full of them. And a new study examines evidence that Pluto may have had an underground ocean all along!

SciShow Space News gives you the update of the historic mission that has, for the first time ever, landed a spacecraft on the surface of a comet!

Black holes! From Stephen Hawking to Interstellar, black holes are mammoths in the world of science AND sci-fi. But what exactly IS a black hole? Do events happen inside black holes? Are black holes really a hole? Are black holes really...

The cell membrane, like a good jacket, protects the cell from everything outside of it. How is it simultaneously sturdy, flexible, and capable of allowing the right things to pass through? Ethan Perlstein rediscovers the scientists and...

If water just keeps getting recycled by a closed system on Earth, how did it get here in the first place? Where did the cycle begin?

There are a few theories that would suggest Jupiter's moon IO has an underground magma ocean. Hank Green explains in this episode of SciShow Space!

In the wake of Hurricane Sandy, Hank answers some frequently asked questions about it, and how it got to be so crazy. What is up with this storm? Has this ever happened before? This is global warming right?

New simulations of a triple-star system in the constellation Orion suggest that a planet might be orbiting three stars, which could drastically increase the amount of the solar systems we believe are out there forming planets! And the...

In 1947, explorers noticed a strange phenomenon while crossing the Pacific Ocean. Somehow, small squid known to live deep beneath the waves kept appearing on the roof of their boat. The crew was mystified— until they saw the squids...

Our planet shares a lot with other rocky planets in our solar system, but astronomers have found a few mountains out there that are nothing like ours.

Ask any deep space navigator like Jill Seubert what makes steering a spacecraft difficult, and they'll tell you it's all about the timing; a split-second can decide a mission's success or failure. So what do you do when a spacecraft is...

You're traveling deep beneath the ocean's surface, where faint lights flicker and toothy grins flash. Your mission is to survive these depths and journey to the surface after sundown to feed. And as a hatchetfish, almost every other...

The Beresheet lander is on its way to the moon and Jupiter's magnetic field might be affecting Europa's ocean.

There are exoplanets out there that seem very Earth-like, but if you look out and see liquid metal instead of liquid water, you might be in the Venus zone.

What's salty and cold and cool as heck? Brinicles, a rarely seen undersea phenomenon the combines ice and saltwater to become every sea star's worst nightmare! Actually, they're not that scary, just awesome. Hank explains within.

Scientists have found at least three cycles in nature that can be traced back to the alignment of the planets. And while they won’t tell you anything about your love life or personality, by studying them, we can learn about our planet’s...

Why would a fish throw up its stomach? What makes a scuba diver develop painful microbubbles in their joints? Neosha S Kashef details the basics of barotrauma, shedding light on how humans and fish alike are influenced by laws of physics...

Mercury is the closest planet to the sun. It has no atmosphere and is, as such, covered in craters. It's also incredibly hot but, surprisingly, has water ice hiding beneath its surface.

We're going to be building on the Moon this decade -- and next will be Mars, says space architect Melodie Yashar. In a visionary talk, she introduces her work designing off-world shelters with autonomous robots and 3D printers and...

Every amazing mission you know about today started off as just an idea, and some of 2019’s early phase NIAC concepts could mean big things for our future.
