The Strangest Star Ever Observed from Earth

The state of our knowledge about the Universe is in a strange place now. We can map countless stars around us, but we seem to be just stumbling upon every discovery. Some of them are so puzzling, even skeptical scientists start to suspect aliens! The brightest example is the Tabby Star, who’s light dims as […]

The helical model – our solar system is a vortex

El viejo modelo heliocéntrico de nuestro sistema solar… …de planetas rotando alrededor del sol… …no solo es aburrido, sino además incorrecto. Nuestro Sistema Solar se mueve a través del espacio a 70.000Km/hr Ahora imagina esto en su lugar: El Sol es como un cometa, arrastrando a los planetas en su estela Puedes ver el “vórtice”? […]

Why Solar Eclipses Create Those Crescent-Shaped Lights

[♪ INTRO] Solar eclipses tend to be pretty big news. The 2017 one in North America was hugely memorable for millions of people, including the SciShow team. And the 2019 one in South America was equally amazing and Instagram-worthy. But during those events, the sky isn’t the only thing people were looking at. They were […]

What’s the difference between a solar and lunar eclipse?

you forget the difference between a solar and lunar eclipse – one looks like this and the sunny day suddenly becomes dark and the other is a full moon that gets darker and darker a lunar eclipse is when the moon is blocking the light from the Sun wait a minute No I changed my […]

Will We Return To The Moon? | Unveiled

Will We Ever Go Back to the Moon? Our constant companion, the moon has been around since long before we arrived on the scene, and will remain after we’re gone. Even so, very few people have had the privilege of exploring the lunar surface. But maybe this will change one day, and something so rare […]

Could a Planet Ever Collide With Earth?

This is the fictional planet Nibiru which has been predicted to slam into Earth, resulting in the end of the world. The scenario is known to doomsayers as the Nibiru cataclysm. It was allegedly supposed to have occurred several times over the last decade but most recently in April of 2018. Needless to say… it […]

NASA | Tour of the Moon

[silence] [silence] [music] [music] Narrator: To nearly everyone, the moon appears to be a sterile, gray, unchanging world. But while the moon has remained largely unchanged during human history, our own understanding of it has evolved dramatically. Thanks to new observations, we now have not only unprecedented views of its surface, but a whole new […]

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. […]

NASA’s New Space Engine Is Powered by Nuclear Fission

From a technology standpoint, there’s not too many greater challenges than nuclear power in space. The physics involved in it is quite intense — it has that luster of something totally different. We start with that highly enriched core, the splitting of the atoms generates that heat that we need at the right power levels, […]
