Back in the day, the ancient Egyptians had dreams of soaring like majestic birds, and they put their imaginations to the test with the Saqqara Glider. It's like they built a wooden wonder, a model airplane, before airplanes even existed. This glider had wings like a bird and the curiosity of an inventor – it's like a time-traveling experiment! Whether it was a prototype for future air travel or just an ancient game of aviation dreams, the Saqqara Glider is like a whisper from the past that's caught our modern imagination.

On July 20, 1969, Neil Armstrong stepped onto the lunar soil, saying, "That's one small step for a man, one giant leap for mankind." Since the Moon doesn't have any wind or rain, the footprints should still be relatively untouched. NASA put in a lot of effort to make sure these footprints stay protected, as well as the location of the initial Moon landing. There are many flags on the surface of the Moon, too. But the flags left there are most likely discolored now because of the exposure to strong solar radiation.

If you look up at the Earth's satellite, the Moon, you'll see that its surface is peppered with thousands of craters. Those are caused by asteroids and meteorites colliding with the lunar surface. But it also has over 200 holes that might even lead to caves. Scientists from around the world keep an eye on them and wondering if they may lead to an underground tunnel system...

Is it possible to permanently settle on the Moon? Yup, but we'd need more advanced equipment, infrastructure and astronauts' outfits. Current spacesuits are great for walking on the Moon but aren't enough for permanent missions. Human body can perfectly function on Earth, but the Moon has different atmosphere and magnetic field. Let's see which upgrades a new spacesuit should definitely have.

How many Moons does our planet have? Sounds like a pretty straight-forward question, doesn't it? The simple answer is that Earth has only one Moon, which we see in the sky every night. The more complex answer is that the number of moons varies over time... How is it possible? In this video I'm gonna explain this to you. By the way, around the Solar System, multiple moons are the rule. Mars has two moons, while Jupiter has over 60 natural satellites. More coolest space facts are coming your way... We'll explore why planets don't twinkle, while stars do. Also, we'll talk abouit space volcanoes: they can spew methane or ice instead of lava. Let's find out more coolest facts about the processes happening in space. #brightside

Have you ever noticed how when you’re stargazing two nights in a row at the same time, let’s say 9 p.m., the stars stay in the same place, but the Moon doesn’t? I've learned the reason for this phenomenon and I'm ready to share it with you! I'll also tell you what exactly happens to the light after it disappears inside of a black hole. Here're 10+ cool space facts you probably haven't thought about!
