How the Pyramids Were Built (Pyramid Science Part 2!)

This episode is supported by Skillshare. Hey smart people, so a few weeks ago we made a video about the pyramids, and how, while they are pretty heckin’ impressive, we can trace the evolution of their construction and see the ancient Egyptians using trial and error, and even making a few mistakes, which basically tells […]

Why Alien Life Would be our Doom – The Great Filter

Imagine NASA announced today that they found aliens. Bacteria on Mars, weird alien fish in the oceans of Europa, and also ancient alien ruins on Titan. Wouldn’t that be great? Well, no. It would be horrible news, devastating even. It could mean that the end of humanity is almost certain and that it might be […]

A Potentially Habitable Super Earth Has Been Discovered

Just in case anyone missed this little bit of news, the universe is big. Shocking, I know. Too big, some think, for us to be the only ones in it. It’s just a matter of knowing where to look, and scientists from NASA’s TESS program might have stumbled across the next clue in this galactic […]

Titan’s Oceans Are Made of Super Cold Methane, and NASA Created Them on Earth!

Scientists are sending a submarine to Saturn’s moon Titan to explore its alien oceans in search for life and to possibly understand how life began on our own planet! Researchers are studying two main oceans on Titan. The Kraken Mare and Ligeia Mare. Both of which were discovered fairly recently by the Cassini space probe. […]

Do aliens exist? If they did, would we know? | NASA astronomer Michelle Thaller

One of the biggest questions is, could there be other life besides us out there in the universe? And I think pretty much every scientist I know feels that there must be. I mean, just simply the numbers– in our galaxy alone, there are half a trillion stars. And we’re now beginning to realize that […]

Saturn’s Mysterious Moons (V1)

Some 900 million miles from the Sun… in the outer regions of our Solar System… orbiting the planet Saturn…. …lies a mysterious world. Enceladus is enveloped in ice. Because nearly all of the sunlight that manages to hit its surface is reflected back into space, it’s one of the brightest objects in the solar system. […]

Strange Magnetic Bubbles at the Edge of the Solar System

The two Voyager spacecraft have been traveling away from Earth for more than 33 years and they are finally in the outer edge of the solar system. This boundary is marked by the outer reaches of the sun’s magnetic field and solar wind, which form an enormous expanse called the heliosphere. As the solar wind […]

Solar Tsunami

The SOHO spacecraft has recorded the effect of all this rising energy. Its ultraviolet sensors show a wavy pattern of gas on the sun’s surface, along with the super-hot halo of gas called the corona. The white regions are places where the rising gas suddenly escapes. Immense loops of ionized gas, ten times the diameter […]

The Last Star in the Universe – Red Dwarfs Explained

One day the last star will die and the universe will turn dark forever. It will probably be a red dwarf; a tiny kind of star. That’s also one of our best bets to find alien life, and might be the last home of humanity before the universe becomes uninhabitable. So, what do we know […]
