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.

The good old Solar System is actually a pretty bizarre place, what with all its out-of-this-world phenomena that we, humans, haven’t managed to explain so far! There are rumors that a gigantic, undiscovered planet is hiding behind Neptune, volcanoes on Pluto spew ice, and a colossal canyon on Mars can accommodate the whole US territory! Well, let’s figure out if it’s true by talking about the most mystifying Solar System facts. The Solar System is 4.6 billion years old! So old — it’s a senior Solar System. Scientists came to this conclusion after they studied the oldest material they managed to get a hold of — and by that, I mean meteorites, of course.

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.

The world’s ocean levels have risen about 4 feet. The Bahamas? They’ve totally disappeared! 200 years from now. The Earth’s population is about 19 billion people.

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.

Is it possible to “put out” the Sun? For example, what would happen if we poured all of Earth’s oceans on it — or even more water? Well, let’s find out. The Universe is a place full of mysteries. Since ancient times, scientists have been arguing about how space works. But none of us has ever doubted the existence of one thing — the Sun. Ah, the center of our Solar system. It’s big, bright, and... immortal? Nah, not really. Actually, the Sun is just an ordinary star. It consists of 75% hydrogen, a little helium, and a pinch of other heavy elements. Gravity holds it all together. But in around 5 billion years, the life cycle of the Sun will come to an end. The hydrogen inside it will run out. Our star will begin to grow gradually. And you can’t even imagine just how BIG it will become!

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.

Among all the planets of the Solar System, our Earth is unique since it’s the only one that has developed life. But what if we got a competitor? What if a second Earth appeared out of nowhere? Then there would be two different scenarios. The first is the destruction of both planets. The second has an unexpected but pretty logical ending. But let’s start with the catastrophic scenario. The second Earth with the same conditions could exist only if it received absolutely the same amount of sunlight as our planet. The orbit that our Earth follows is perfect for getting the necessary amount of solar heat. If we were a little further away, the entire surface of our planet would resemble Antarctica. And if Earth was a little closer to the Sun, we’d all live in a huge desert inhabited by very few living beings. So, for the second Earth to be identical to ours, it’d need to follow the orbit of our planet.

The star is probably still forming and is no more than 5 million years old. For comparison, our Sun is 4.6 billion years old. The young star is located around 531 light-years away from Earth in the constellation of Auriga.

Black holes. The most terrifying, mysterious, and fascinating objects in the Universe. Eternally hungry, they eat everything in their path and are constantly expanding. But how small and how big can a black hole be? Let’s find out. It’s not very easy for a black hole to be born. Most often they’re just a result of a massive star ending its life cycle. If you take a star and squeeze it very, very hard, at some point it cannot withstand the pressure anymore. So it collapses and turns into a black hole.

Well, let’s find out. This here is a giant molecular cloud. They’re also sometimes called dark nebulae. Here, there are many interstellar clumps full of gas, dust, and piles of stars. These clouds have no clear boundaries and often take weird crazy forms. You can even see some of them with the naked eye. Look at the clear sky at night — they look like dark spots all across the bright Milky Way.

It’s hard not to wonder if there’s another form of life out there in the Universe when you look at the night sky. There’s this thing called Fermi Paradox. It basically says this: if civilizations that might live somewhere out there in the Universe are so common, why haven’t we found any signs of them? We’ve looked really hard, but we haven’t stumbled over any proof there are other forms of life somewhere in space. And we suspect there could be many civilizations because scientists have calculated there are possibly billions of habitable planets in our galaxy alone. So it would seem reasonable to assume that some of these planets could have developed intelligent life, possibly even civilizations that are more advanced than ours. So, Fermi Paradox basically asks, “Where’s the party? How come we weren’t invited?” And one of the potential answers to why we haven’t found any other form of life in the Universe is something called the Great Filter theory.
