Space Parachutes: Predicting the Unpredictable
Parachutes are a big part of keeping our astronauts safe, but despite being around for almost 500 years, there are still a lot of things we need to work on before they can be full proof.

Journey to the Center of a Neutron Star
There are a lot of incredible things in space, but neutron stars are some of the most mind-blowing. From liquid plasma oceans on the surface to a possible neutron superfluid in the core — as you go deeper into a neutron star, the physics...

There’s a Rectangle Galaxy?
You're probably used to real galaxies having curves, except not all of them seem to have gotten the memo.

The Two-Faced Role of Planetary Magnetic Fields
Given that Earth’s magnetic field helps protect its life-sustaining atmosphere, you might think that the stronger a planet’s magnetic field, the better. But as it turns out, some planets’ relationships with their magnetic fields are a...

Can You Build Homes in Space With Blood?
If we hope to someday live on other worlds we need to figure out where we’re gonna lay our heads at “night.” But who would have thought we could use our own bodies as ingredients for our homes?!

Jupiter's Moons May Keep Each Other Warm
As small as Jupiter's moons are in comparison to the giant planet, they may actually have an important role to play in keeping each other warm, heating the moons enough to have liquid oceans!

3 Cosmic Time Capsules
Long before we were around, the universe was preserving clues about the distant past, in everything from little balls of carbon to huge groups of stars.

Earth Doesn’t Orbit the Sun
Understanding gravity can sometimes be a bit of a balancing act, much like the fundamental laws of physics and how they inform what it is exactly that Earth orbits.

How to Clean Up After Ourselves in Space
We've launched thousands of spacecraft over the years. And as the space junk around our planet builds up, researchers are working on ways to clean things up using some obvious things, like lasers, and some less obvious ones, like solar...

From Kepler to Webb: The History of the Telescope
Hank regales us with the history of the telescope, and then introduces us to some folks from the team who are working on the newest telescope in the chronology - the James Webb Space Telescope, an infrared telescope due to launch in 2018.

Dark Matter Is Even Stranger Than We Thought | SciShow News
Scientists can see how dark matter is distributed based on how its gravity affects light, but when astronomers compared recent data from the Hubble Space Telescope and the Very Large Telescope to current models, something didn’t add up....

Using Microbes to Mine Mars: The Future of Biomining
Humans have been using microbes to separate minerals from mud since the middle of the last century, so we know biomining works on earth. But how will these tiny miners work in microgravity?

The Farthest Galaxy We've Ever Seen! | SciShow News
Scientists have spotted a galaxy from the early origins of the universe, and found evidence to support the existence of a 9th planet in our solar system.

Can We Change Earth’s Orbit?
Climate change is a big problem, but could we solve it by giving the earth a little nudge?

How 19th Century Lighthouses Power Advanced Space Drives
The technology we use for space exploration gets more advanced all the time, but some of our most ambitious programs actually rely on optics invented in the 19th century for lighthouses.

Mama, Where Do Galaxies Come From?
For most of human history, we didn't know that galaxies were a thing. So over the past century, astronomers have been working to understand how galaxies come to be and how they evolve over time. And for a full decade, there was one...

How Other-Worldly Auroras Help Us Explore the Galaxy
Earth’s northern and southern lights are some of the most magical sights on our planet. But they’re not unique to Earth, and aside from being beautiful, auroras can also give us unusual insights into these other worlds.

The Most Sophisticated Mirror in the Universe
Hank summarizes the five reasons why infrared telescopes were supposed to be impossible to build, and then describes how a team of scientists and engineers overcame those obstacles to build the James Webb Space Telescope.

The Equator Is a Bad Place for These Rocket Launches
Some satellites orbit in the same direction the planet rotates, which means they get a boost for their launch, but most have orbits where that isn’t ideal, and that creates some challenges for engineers.

3 Ways Exoplanets Rocked Planetary Science
Exoplanets have taught us a lot more about planets than our solar system could ever teach us, from what happens when they’re born, to what happens when their stars die.

Where Did the Big Bang Happen?
The name “The Big Bang” makes it sound like there was a big explosion in one particular spot, but if that’s the case, where did it happen?

The Oldest Crater from a Meteorite…Isn’t a Crater after All?
There's one crater that may be older than any that we know of. Except there's a snag, it might not actually be a crater at all.

What Do You Learn When You Touch the Sun?
Though our Sun is something we can count on to rise and set each day, it also comes with some phenomena that can catch us by surprise: solar winds. To better predict when these winds will travel all the way to Earth, we sent the Parker...

The Hottest Exoplanets in the Universe
With exoplanets, often we want to know if they are Earth-like and whether they might host life, but we can also learn a lot from planets that are nothing like Earth.
