This is the story of how the era of ancient reptiles came to an end. The last day of dinosaurs. This is a documentary about the day the dinosaurs died.

Brain size relates more to proportion than it does to intelligence. Your brain is smaller than a whale’s because your body is smaller. However, your brain is structured in a way that enables you to survive, and succeed. But after all that, would you believe that humans only use 10% of their brains? Let’s make it 100%.

If time travel is possible, why haven't we met a single time traveler yet? And if we did meet one, how would we know they weren't faking it? What would their time machine look like?

NASA's Plan To Stop An Asteroid Before modern telescopes, humans could only imagine what the surface of the sun and the planets looked like. Now advanced technology has made it possible to get in close, and take images of the Sun and the planets deep in our solar system. Now get ready to see the solar system as you’ve never seen it before, and see images that were so good they shocked astronomers.

Massive glaciers, staggering mountains, plains dotted with wild animals: We sure live in a big, beautiful world. And while pinpointing all of Mother Nature's greatest hits could take a lifetime, we think these out-of-this-world landscapes and awe-inspiring wonders, from Arizona to Antarctica, need to move to the very top of your travel list.

Correction: we mixed up the Sun‘s lifespan with its age. Of course the sun is only about 4.6 billion years old, half way through its lifespan of about 10 billion years. That star at the center of our Solar System, that superhot ball of plasma that gives us heat and energy, and amazing complexions...well, it's a ticking time bomb. The Sun is about 10 billion years old. But it's only expected to last about another 5 billion years. After that, the Sun will expand, becoming a red giant. Then it will shrink to become a white dwarf, a dying star, cooling for the next several billion years. Of course, we'll all be long gone before any of that happens. But still, can you imagine what it would be like to watch the Sun blow up before your very eyes?
