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...

Minority Report science adviser and inventor John Underkoffler demos g-speak -- the real-life version of the film's eye-popping, tai chi-meets-cyberspace computer interface. Is this how tomorrow's computers will be controlled?

Light always travels at a speed of 299,792,458 meters per second. But if you're in motion too, you're going to perceive it as traveling even faster -- which isn't possible! In this second installment of a three-part series on space-time,...

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!

Scientists can’t directly observe dark matter, and they still don’t know what it is… so why are they so confident it exists?

There’s a big difference between the number of satellites that simulations predict, and the number we’ve actually seen with telescopes, but why?

Robert Lang is a pioneer of the newest kind of origami -- using math and engineering principles to fold mind-blowingly intricate designs that are beautiful and, sometimes, very useful.

Is there more than one universe? In this visually rich, action-packed talk, Brian Greene shows how the unanswered questions of physics (starting with a big one: What caused the Big Bang?) have led to the theory that our own universe is...

On this Space Time Journal Club we look at how gravitational waves can be used to search for extra dimensions of space!

SciShow’s Executive producer Hank Green faces off against SciShow senior editor Alyssa Lerner in this Quiz Show about weird experiments and strange animal parts.

What exactly are the invisible things out there, and how did they help form the universe as we know it? To explore and understand the most spectacular structures out there, scientists have been using cosmic shear to indirectly detect...

This video is about how I designed and made my own custom mute guitar pedal for my clip-on mic and piezo pickup on my violin (fiddle). The mic is an AT Pro35 phantom powered XLR condensor microphone, and the pickup is a Fishman V200...

There's a lot more to Saturn's rings than just looking awesome! Find out why!

What is a vector space? Even though they are initial taught in the context of arrows in space, or with vectors being lists of numbers, the idea is much more general and far-reaching.

Last time, we learned that there is in fact weather on other planets. But those were the rocky planets, like Earth. What about the big Gas Giants? What's the weather like there? In this episode of Crash Course Kids, Sabrina takes us on a...

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...

Astronomers have theorized about an invisible star made up of theoretic particles in the past, but did we recently detect the gravitational waves of two of them colliding? Plus, extraterrestrial rocks from a decades-old mission keep...

Moser's circle problem. What is this pattern: 1, 2, 4, 8, 16, 31,...

Danielle Wood leads the Space Enabled research group at the MIT Media Lab, where she works to tear down the barriers that limit the benefits of space exploration to only the few, the rich or the elite. She identifies six technologies...

Our favorite fast radio burst, FRB 121102, brings us one step closer to understanding its source, and astronomers have a new theoretical upper limit for star masses.

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...

Reid Reimers explains one of the often-overlooked technologies that humans need to live in, and explore, space: space suits. Learn about the hundred-year history of the pressurized suit, and see what the future of space couture might...
