Volcanoes are amazing: explosions, rocks flying up high, lava rivers flowing down the slopes, clouds of ash filling the air. There're about 1,500 potentially active volcanoes on Earth and we're already watching 19 of them closely. They might explode awake any minute... Like the volcano in Iceland that suddenly woke up after 800 years!

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.

Wireless electricity isn’t just a sci-fi dream anymore — it’s actually happening! Scientists around the world are building systems that can send energy through the air, and it’s already being used to power things like smart locks, sensors, and even electric toothbrushes. In the U.S. and Japan, researchers are testing ways to wirelessly charge drones, satellites, and even entire city grids. One of the coolest ideas is using an infrared beam, kind of like Wi-Fi, but for charging your stuff. Japan’s space agency, JAXA, is even planning to launch a solar power station into orbit by 2030 that could beam energy straight down to Earth. If it all works out, wireless power could make chargers and batteries a thing of the past — and seriously help the planet too!

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.
