A fun nightmare sci-fi scenario is the sun being consumed by a black hole. Fortunately the chance of a black hole randomly wandering into our solar system is pretty tiny. That’s good news. But what if it’s already here, hiding in the...

Solar eclipses can happen anywhere on earth, but if you want to see a total eclipse, you need to go to the far north, because the Earth’s shape and orbit determine the high latitudes and eclipse hotspot.

From its life-sustaining energy to its explosive geomagnetic storms, the Sun has many mysteries, says astrophysicist Nour E. Rawafi. He sheds light on NASA's latest endeavor to better understand our fiery neighbor and its impact on the...

In 2022, physicist Tammy Ma and the team at Lawrence Livermore National Laboratory achieved a scientific breakthrough decades in the making: fusion ignition, or the combining of two atoms to generate more energy out of a reaction than...

In this SciShow Kids episode, Jessi and Squeaks learn about amazing places where it almost never rains.

Stars have cores hot and dense enough to force atomic nuclei together, forming larger, heavier nuclei in a process known as fusion. In this process, the mass of the end products is slightly less than the mass of the initial atoms. But...

Unlike Earth, our Sun is a giant ball of mostly hydrogen and helium. Astronomers managed to figure that one out roughly 100 years ago. But after all this time, they still can't come to an agreement on what "mostly" means, precisely.

From cyclones to snowstorms, Earth is home to some spectacular weather events. But they're nothing compared to what you can find on the other planets in our solar system. Magnetic tornadoes? Ammonia mushballs? Let's (not literally) dive...

If you could survive a trip to the very first moments of reality as we know it, what color would you see?

The Moon is typically 380,000-ish kilometers from the Earth, so it doesn't seem like they have that much of a direct influence on one another. However, the presence of hematite on the lunar surface suggests our planet is causing the Moon...

In 2010, NASA announced the discovery of a never-before-seen galactic object: two gigantic gaseous bubbles, each emanating an impressive 25,000 light years from the center of the Milky Way. Astronomers were perplexed: what created these...

In 2021, the Parker Solar Probe fulfilled its mission to “touch the Sun”. But the temperature over there was millions of degrees Celsius. How did the spacecraft not melt?

It’s common knowledge that you should never look directly at the sun. But, like, what about during an eclipse? Surely you can look then?

Ancient perceptions of lunar eclipses weren’t as primitive as one might think. Some rigorous math was applied to these cosmic events that shaped our understanding of the solar system.

Figuring out the age of a blinking speck in the sky is a difficult feat, especially if considering how many types of stars there are. This is where a Hertzsprung-Russell meets a gyrochronologist.

While doing some light reading of data from a telescope, Conny Aerts made a breakthrough that allowed her to lead the charge in the field of asteroseismology and win her the 2022 Kavli Prize in Astrophysics.

If we’re going to send people to Mars someday, we’re going to need to be very conscious of the challenges presented in this endeavor. And at the top of that list is the ferocious nature of dust on the barren planet.

Earth and the other seven planets in our solar system have only one star: the Sun. Years ago, astronomers found the first exoplanet that had two stars. They also found one with three stars. And four. Just how many stars can one planet have?

What do we do to protect ourselves from extinction level events? And what if some of those events are unavoidable? Can we survive adrift in space? Find out in this episode of Space Time.

Planck's Length is the length below which the concept of length loses its meaning. What exactly does that mean and what are the incredible implications this fact has upon our reality? To find out check out this episode of Space Time...

Mercury, Venus, and Mars are all super low on water – so where did ours come from and why do we have so much of it? We think our water came from a few unlikely sources: meteorites, space dust, and even the sun.

Throughout the Pleistocene Epoch, the range of the woolly rhino grew and shrank in sync with global climate. So what caused the climate -- and the range of the woolly rhino -- to cycle back and forth between such extremes?

According to the Skin Cancer Foundation, everyone older than six months should use sunscreen every day to decrease the risk of skin cancer. But today’s sunblock is full of ingredients that are decades old and increasingly obsolete. Dr....

If the sun instantly switched off like a light bulb–which can’t happen, by the way–then we wouldn’t know for almost 8 and a half minutes. Light travels at the fastest speed there is, but it still takes almost 500 seconds to get to Earth....
