In 1965, during the Gemini 4 mission, astronaut Ed White became the first American to spacewalk. While it was a historic moment, it was also nerve-wracking as it was a brand-new and untested endeavor. In 2013, Italian astronaut Luca Parmitano faced a terrifying situation as his helmet started filling with water during a spacewalk, prompting an immediate return to the ISS. The 1984 spacewalk by Bruce McCandless, using the Manned Maneuvering Unit, showcased breathtaking views but also highlighted the isolation and potential dangers of untethered spacewalks. The challenges of spacewalking are a great reminder of how much courage and resilience it takes to be an astronaut.

The Solar System formed billions of years ago. The vast majority of the system's mass is in the Sun, which is its center. And even though we live in it, the Solar System still has plenty of secrets to unveil. Strange phenomena, incredible objects, dwarf planets and hybrid meteorites. And the timeless question: what's inside a black hole? Let's take a look at these 10 mysteries about our Solar System that have yet to be solved.

Scientists discovered a colossal worm lurking in the ocean depths, big enough to make a Megalodon shark look like a minnow! This monstrous creature, known as the "Wormzilla," challenges our understanding of marine life and what's possible in the depths. But wait, there's more! The ocean never fails to surprise us—how about glowing sharks that emit light from their bellies, or fish that walk on the ocean floor using leg-like fins? Then there's the "psychedelic Medusa," a jellyfish that pulsates with vibrant colors as it drifts through the deep. And don't forget the "zombie worms" that feast on the bones of dead whales, thriving in one of the most extreme environments on Earth. It's a wild, weird, and wonderful world down there!

Are you ready to dive into the deep blue sea and uncover the real reason we're not ocean explorers extraordinaire? The ocean is hiding in plain sight, and we humans love shiny stuff on land more than underwater gems. The ocean gets super intense, and our human bodies just ain't built to handle that underwater squeeze. And don't forget the technology struggle. The ocean's depths are tricky, and our tech is still figuring out how to handle all those challenges. And last but not least, the ocean is like a VIP club for some exclusive marine creatures.

The ocean's "false bottom" is a remarkable phenomenon that occurs in certain marine environments. It's not a physical layer but rather a fascinating optical illusion. In crystal-clear waters, when you look down into the sea, it can seem like you're peering into an abyss with no end in sight. So, when you think you're seeing an endless abyss beneath you, you're actually experiencing an optical distortion. In reality, there's a true ocean floor that might be much closer than it appears, hiding beneath the illusion of the "false bottom."

They call it the Grand Canyon for a reason, right? It's grand, big, huge! You could fit the whole of Manhattan into it! But the Valles Marineris on Mars is way bigger, almost 10 times the size of our "little" Grand Canyon! Mariner Valley covers nearly a quarter of the way round the Red Planet. Here on Earth, it'd cut all the way across the US coast-to-coast...plus some!

Our solar system is full of mind-blowingly huge canyons and chasms. There’s Tiu Valles, where researchers think there was once water on Mars and boiling volcanic lava! Even right here on Earth, the Grand Canyon has some serious rivals. Yarlung Tsangpo is the deepest on our planet. Some people call it the “Everest of Canyons” - you could fit a 2,000 story building in it!

Take a journey across our solar system and get to know our own home planet a little better by looking at the biggest, deepest, longest, and most strikingly beautiful canyons out there! ?
