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...

The hunt for dark matter is still on, and the candidates for it could be primordial black holes as massive as Earth, or axions, as tiny as the smallest subatomic particles in existence!

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.

A new study provides mathematical evidence that dark matter could be much older than we thought and we've found a weird glitch in a neutron star.

Artist Sarah Sze takes us on a kaleidoscopic journey through her work: immersive installations as tall as buildings, splashed across walls, orbiting through galleries -- blurring the lines between time, memory and space. Explore how we...

Long before we had rocket scientists, the idea of spaceflight traveled from mind to mind across generations. With great visuals, TED Fellow and NASA economist Alexander MacDonald shows how 300 years of sci-fi tales -- from Edgar Allan...

You've discovered a habitable exoplanet, but so has an an evil interplanetary mining corporation. Can you get to the planet before they strip it bare and leave it unsuitable for life? You're going to need a ship, the Lorentz...

Is teleportation possible? Could a baseball transform into something like a radio wave, travel through buildings, bounce around corners, and change back into a baseball? Oddly enough, thanks to quantum mechanics, the answer might...

What happens when you set off a nuclear bomb in space? Turns out we have a pretty good idea, and it's not pretty. Learn about the science behind high-energy explosions in space.

Observing the effects of microbes using satellites can give us all sorts of useful information about life on Earth ... and other planets too.

Scientists may have found the light from two merging black holes, and a gas giant, without the gas.

TeD Fellow Carrie Nugent is an asteroid hunter -- part of a group of scientists working to discover and catalog our oldest and most numerous cosmic neighbors. Why keep an eye out for asteroids? In this short, fact-filled talk, Nugent...

We all know space travel is pretty dangerous, but here are a few more things that you probably wouldn't have thought to look out for!

Asteroseismology allows scientists to explore stars with sound. It can help them figure out what a star is burning and even help pin down the age of stars!

Many galaxies formed fast after the Big Bang, but about half of them suddenly stopped making new stars and it looks like this is literally because they ran out of gas. And with new instruments and techniques, we are now finding lost...

When stars die, they tend to take everything around them with them. But new evidence appears to show a planet orbiting a white dwarf, and we’re not sure how it survived! Plus, experiments designed to detect dark matter might be capable...

The pandemic spurred an unprecedented reclamation of urban space, ushering in a seemingly bygone era of pedestrian pastimes, as cars were sidelined in favor of citizens. Highlighting examples from across the United States, environmental...

On SciShow News this week, Hank explains how it can rain on the sun and dives in to findings from the NASA twin study!

We don’t know what happens to stuff when it gets sucked into a black hole, but in the same instance, we don’t know what happens to the black hole. There’s a possibility that sucked up stuff might actually give the black hole “quantum hair”.

We're in the dawn of a new space revolution, says engineer Peter Beck: the revolution of the small. In a talk packed with insights into the state of the space industry, Beck shares his work building rockets capable of delivering small...

Can't wait to get into outer space? Well there's a bit you need to know first... Spending time in zero gravity can have some pretty extreme effects on the human body. Still scientists are already making plans for long trips to other...

When Quasars were first discovered the amount of light pouring out of such a tiny dot in space seemed impossible. A hysterical flurry of hypothesizing followed: swarms of neutron stars, alien civilizations harnessing their entire...

Engineer RA Mashelkar shares three stories of ultra-low-cost design from India that use bottom-up rethinking, and some clever engineering, to bring expensive products (cars, prosthetics) into the realm of the possible for everyone.

How does cancer know it's cancer? At Jay Bradner's lab, they found a molecule that might hold the answer, JQ1. But instead of patenting it and reaping the profits (as many other labs have done) -- they published their findings and mailed...
