Our Milky Way galaxy is alive and well, producing new stars all the time. But there’s another group of galaxies out there, populated only by venerable red dwarf stars - the young stars are nowhere to be seen. In effect, these galaxies...

As we look towards longer missions to the Moon, the shear amount of resources needed to survive becomes a much bigger question. Without space semi-trucks to haul life-giving resources to astronauts, can we utilize the Moon’s barren...

Spray-painted subway cars, tagged bridges, mural-covered walls -- graffiti pops up boldly throughout our cities. And it turns out: it's nothing new. Graffiti has been around for thousands of years. And across that span of time, it's...

Real World Telekinesis (feat. Neil Turok)

Taking inspiration from nature, architect Ma Yansong designs breathtaking buildings that break free from the boxy symmetry of so many modern cities. His exuberant and graceful work -- from a pair of curvy skyscrapers that "dance" with...

This week on SciShow Space News we're talking about gravity waves (not gravitational waves) on Pluto, and radioactive interstellar rain on Earth!

This video explains Shor’s Algorithm, a way to efficiently factor large pseudoprime integers into their prime factors using a quantum computer. The quantum computation relies on the number-theoretic analysis of the factoring problem via...

The universe is a pretty grand place to live, but scientists have one issue with it, it's an anomaly that should be scientifically impossible.

When you’re learning about science for the first time, it can be easier to break things down into a simpler form, and you can end up with a few misconceptions about the world. But sometimes this is the first step to understanding that...

Passionate scientists constantly have revolutionary ideas, but when they seem too good to be true, they usually are.

In which John Green, Hank Green, and Emily Graslie teach you about what happened in the Universe after the big bang. They'll teach you about cosmic background radiation, how a bunch of hydrogen and helium turned into stars, formed...

Our universe started with the Big Bang, but how will it end? Explore cosmologists’ three possible scenarios: the Big Crunch, the Big Freeze and the Big Rip. -- We know about our universe’s past: the Big Bang theory predicts that all...

This video explains how Shor’s Algorithm factors the pseudoprime number 314191 into its prime factors using a quantum computer. The quantum computation relies on the number-theoretic analysis of the factoring problem via modular...

At the beginning of the 20th century, many scientists thought that we had learned all there was to know about physics. The problem is, the better we get at measuring things and building models of our universe, the more we discover that...

Scientists are always searching for new materials that maximize strength and thermal protection while also minimizing mass for space flight. So, when developing new heat shields, why are they looking to cuttlefish for inspiration?

Dr. Who is one of the longest running TV shows on the BBC, and it's got a huge fandom surrounding it, called Whovians. And while it might not seem like, Whovianism, might just be religion! Whovians, like other passionate fan cultures,...

In this video Paul Andersen explains how inertial mass is defined and measured. When a force is applied to an object or a system it will accelerate. Using Newton's Second Law of Motion (F=ma) you can calculate the inertial mass.

This week we’re exploring aerospace engineering and its two main fields: aeronautical engineering and astronautical engineering. We’ll explore life & buoyancy, propulsion systems, and the challenges of managing the human body in space.

Pulsed plasma thrusters use the same stuff that’s on your frying pan to make spacecraft zoom around the universe. And they’ve been doing it since the 1960s.

Find out about China's current telescope on the moon and what the future plans are for mounting larger telescopes on the lunar surface.

Scientists are working on creating organisms with designer genomes -- and someday, we might end up with bacteria manufacturing our jet fuel.

In which Hank and John Green teach you a Crash Course on the modern revolution, and the upside of the progress that humanity has made in the last 500 years or so. And while there are two sides to every history, and many of these changes...

The universe that we know, with its luminous stars and orbiting planets, is largely made up of elements we can't actually see -- like dark energy and dark matter -- and therefore don't fully understand. Theoretical physicist Chanda...

The Astrophysics Pioneers program is funding four innovative new missions that read like a best-hits album of the most exciting astronomical frontiers: from galaxy evolution and exoplanets, to neutron star mergers and astroparticle physics.
