Ahh, Earth... the third rock from the Sun. The blue planet. You get it. Its atmosphere is made up of around 78% nitrogen, 21% oxygen, and 1% argon, water vapor, and carbon dioxide, a nice balance for any living creature to breathe. The weather here is also perfect for life to exist, unlike in places like Saturn, Mercury, or any other celestial object in our Solar System — we have the troposphere to thank for that. It’s the densest part of the atmosphere on our planet and is 5 to 9 miles thick. It’s the layer of the atmosphere that always affects our weather and secures the right conditions for life to exist and to have bodies of water.

In our Solar system, most planets spin counterclockwise — but not Venus. This rebel planet decided to spin clockwise, and scientists are still trying to figure out why. By the way, why do planets rotate in general? What defines the speed of their rotation? Does the Sun rotate? Buckle up and let’s try to answer these questions. Venus is the second planet from the Sun and the hottest planet in our Solar system. Did you know that Venus is sometimes called Earth’s “twin”? That’s because it’s similar in size and composition to our own planet. But that’s where the similarities end, because Venus is a pretty crazy place, to say the least. For example, the weather. On Venus, it’s always hot and cloudy. And when I say “hot”, I mean it — it’s like over 800°F there! And those clouds? They’re not made of water like the ones on Earth. Instead, they’re made of sulfuric acid. So yeah, you wouldn’t want to go outside without a really good sunscreen on Venus.

You’re on a plane heading to an important astronomy convention when you see a large figure outside your window that eclipses the whole Sun. You spit out all of your coffee, and everyone in the plane stares outside in shock. You then notice that it has rings like Saturn. You were supposed to fly to Japan, but you’re forced to land in California.As soon as you land, you look up in the sky and see some more giant planet-like structures floating around in the sky. Everyone is taking pictures and trying to figure out what’s going on. Suddenly you notice a huge ball of fire crashing down near the airport. Everyone scrambles for safety, and luckily, it ends up in the middle of the runway with no one around. The bad news is that there’s no more runway for planes to land.

We’re flying past the planets of our Solar System. We pass by Mars, Jupiter, Saturn, Uranus, and Neptune. Then we move through dark space beyond the edge of our world. We’ve reached our destination. It’s the Oort cloud. It’s a hypothetical region around the Solar System that holds tons of asteroids and blocks of ice. It’s likely to be where the largest comet in human history was born. And now, it’s heading toward the Sun! Bernardinelli-Bernstein was discovered totally by accident during the Dark Energy Survey. Our telescopes were pointed at distant space. Their main goal was to learn more about how the Universe was expanding. Astronomers also wanted to make a more detailed map of the observable universe.Scientists analyzed over 80,000 images and found a moving object. It was alarmingly close to our home planet. Its size was an impressive 62[ml (100 km)] miles. That’s about the width of Lake Michigan. It was an already active comet with a long tail. Usually, comets get a tail when they come close to the Sun. The heat from the star warms the comet’s surface, and light materials, like ice, begin to evaporate. This forms a cloud of steam and dust that stretches far beyond the comet.

You take off from Earth and park your spacecraft somewhere near the Moon. You’re now almost 240,000 miles away from your home planet. That’s almost 100 widths of the United States. Now, you take out a giant hammer and an enormous chisel using the robotic arms of your spaceship. You place the chisel at the Earth’s North Pole and strike its head with the hammer. Earth splits open like an eggshell, and you see it... Another planet.It’s Theia. And it’s hiding inside our planet like a yolk in an egg. You’d need to go back in time 4.5 billion years to find out how it got there. This beautiful nebula will soon become our Solar System. Colored dust and various space debris are slowly coming closer toward the common center. Soon this jigsaw puzzle of debris becomes too heavy and dense. The temperature inside the giant is rising. Soon, it gets so high that it triggers a nuclear chain reaction.

The Sun, our majestic and life-sustaining star, has been a constant presence in our skies since time immemorial. Its radiant energy provides warmth, light, and the conditions necessary for life to thrive on Earth. But have you ever wondered what would happen if our Sun suddenly vanished and was replaced by another star?Arcturus. A huge red star. It’s just bursting from inside out! The red sea of plasma on its surface rages and pulsates. This star burns anything that comes close to it. And now... flop! Arcturus is gone! But at the same moment, it reappears at the center of our solar system, replacing the Sun. What we see in the sky isn’t a small yellow dot anymore, but a giant red ball. It’s 25 times wider and 30% heavier than the Sun.

I hope you feel well-rested. Because I’ve got a tough task for you. Don’t worry — it’s fun! You’re going to visit different planets of our Solar System and try to run on each of them! Let’s figure out where you can run the fastest and where you can barely walk! The fastest man on Earth, Usain Bolt, can run with an average speed of about 23 miles per hour. But his top speed is higher — up to 27 miles per hour! Sadly, we can’t all be Usain Bolts. The average person runs at a speed of 6 to 8 mph. But maybe, there’s a planet out there where you can beat the famous Jamaican sprinter’s records? But first things first, what will affect your speed when you run on other planets? For one thing, gravity. Depending on how strong it is on the planet you visit, it’ll influence your weight. And in most cases, the heavier you are, the more slowly you run.

If you landed on Mercury, the first thing you’d notice would be how close it is to the Sun. It’s actually the closest planet to the big ball of fire and the smallest. But it’s not the hottest planet. Venus takes credit for that. It takes Earth 365 days to orbit the Sun, and it takes Mercury more than 3 months. Well, 88 days, to be exact. The days are boiling hot, with the temperature reaching above 800 °F (425 °C). But on the other side of the planet that the Sun doesn’t reach, the temperatures drop to −300 °F (-180 °C). Mercury’s atmosphere can’t hold any heat when it’s nighttime, just like a desert. Deserts have no atmosphere, which is why they have no moisture, and no clouds or rain.If you manage to get from one end of the planet to the other and always stay in between the scorching heat and freezing cold, then you can survive. But oxygen isn’t a friend to Mercury’s atmosphere. So you’d just live for as long as you can hold your breath. Plus, there’s a magnetic field that has solar winds from the Sun that create plasma tornadoes.

Let’s pretend that humanity faces a huge threat from outer space. We’ll imagine that a giant planet-eating octopus comes to our solar system to eat Venus, Mars, Earth, Jupiter, and other planets, except Saturn. Therefore, people decide to move to the big planet with giant rings. Fortunately, they already have cool technologies that allow them to make such trips. So, we quickly get into giant ships, take off, and fly to Saturn. Life on the planet itself is impossible because it has no solid ground. The ship won’t be able to land there. This is a giant gas ball that is 9 times wider than Earth.

Mercury gets a bad rap for always being hot, but that’s not entirely true. The planet’s got no atmosphere, so its temperature swings are wild. When it’s facing the Sun, it can get up to a blistering 800°F, but when it’s turned away, it drops to a frigid −290°F. The reason for this is that Earth has a cozy atmosphere that keeps our temps in check. Mercury doesn’t have that luxury, so it’s at the mercy of the Sun’s rays. But despite all that, Mercury’s still worth checking out. It’s close to the Sun, which makes it a prime spot for studying how solar radiation affects planets. And even though it’s not exactly hospitable to life, there are still plenty of mysteries to unravel.

Tyrannosaurus, Triceratops, Velociraptor... All gone. But because of that, we’re all alive! According to science, the human race was developing more safely without these gigantic creatures hunting us. But what if that asteroid had crashed to the ground a few miles away from the place where it fell? What would the world be like today?

Then there are meteoroid impacts. Thermal quakes occur when the frigid lunar crust expands. It happens when the morning sun illuminates the satellite after a two-week-long deep-freeze lunar night.

There were some physiological obstacles. Astronauts had to deliver tons of equipment and energy-generating and life-supporting systems to the Red Planet.

I have to say — it would be hard to visit the biggest waterfall in the world because it’s underwater. Deep down below, there are fissures and caverns on the ocean floor. They form when water oozes through the layers of salt that are beneath it. This water is filled with dissolved salt. This makes it denser than the water surrounding it, which is why it ends up settling into these fissures. Such type of dense water forms a massive waterfall near Denmark. It’s a giant cascade that plummets 11,500 feet. That’s over three times the height of the well-known Angel Falls in Venezuela. So, the colder water of this waterfall sinks after it collides with the surrounding water that’s less dense.
