Solar tornadoes are not tornadoes, and scientists are studying a black hole with a telescope bigger than the earth!

For the first time ever we have visual confirmation that black holes actually exist and we got it with a telescope the size of our planet.

Everyone is watching the sky during a solar eclipse, but but if you look down, you'll catch another kind of light show.

Space technology gets applied in all sorts of ways down here on Earth, making us more comfortable, healthier, and even saving lives!

A trip into space produces physiological effects in human beings, but it can also change a person in a profound, psychological way.

We’ve discovered what appears to be the first known moon outside of the solar system and new models of Europa’s surface predict the presence of ice blades!

Hank and the gang return with SciShow Quiz Show, where Sci Show's resident geniuses compete to win prizes for our subscribers!

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.

Why Raindrops Are Mathematically Impossible

From the very large to the very small, the universe is an amazing place. Here's my favorite ways to explore its scale.

Quantum mechanics may not seem like it has anything to do with human psychology, but some psychologists are starting to borrow concepts from the field to help make human behavior more predictable.

This video is about how the way we describe the world can influence the way we perceive it. In particular, with regards to Bohmian mechanics, Schrodinger wave functions, Feynman path integrals, and Galilean moons attached to Jupiter by...

This video is about how Albert Einstein made a mistake when applying the Field Equations of General Relativity to cosmology (in particular, to a static, constant density universe), and solved the problem by introducing the cosmological...

Caitlin Hofmeister gives you the latest news from around the universe, including Kepler's latest exoplanet discovery, an upcoming solar eclipse, and a breathtaking image from Hubble.

It's been a year since astronomer Tabetha Boyaijan found strange signals coming from a star called KIC 8462852, aka Tabby's Star. Now, new research shows that it's even stranger than we thought. Plus, good news from spaceflight company...

This week on SciShow Space News, we’re learning more about the side effects of space travel… from mice. Plus, we explore the most luminous galaxy!

Hank explains how a recent astronomical discovery made in Antarctica could change what we know about the birth of the universe, and the rules of physics that govern it.

This video is about what would happen if we built a giant ring around earth – what would happen to the ring, that is. Would if fall? Collapse? Start spinning? REFERENCES: Why Isn’t It Faster to Fly West? Video...

We’ve got some new evidence for water beneath Jupiter’s Great Red Spot, and a new model of Jupiter’s weird magnetic field.

We’ve sent more spacecraft to Mars than any other planet, but around half of the probes that have ever attempted to explore Mars have either crashed or disappeared.

Ever wonder what seasons are like on other planets? Astronomers are beginning to find out, and SciShow Space explains how they know, what causes the change in seasons, and what 'summer' might mean on distant worlds.

Astronomers have finally observed what causes pulsating auroras, and our estimates of the mass of the Andromeda Galaxy have shrunk.

Theoretical physicist David Deutsch delivers a mind-bending meditation on the "great monotony" -- the idea that nothing novel has appeared in the universe for billions of years -- and shows how humanity's capacity to create explanatory...

Some of the universe's biggest action is a result of its smallest stuff
