It’s there, I finally see it, for the first time in my life! A grayish body far away in the sky, hidden behind the clouds, the size of 1-4 of a full moon. It won’t be there for long, the last time it was there was 33 years ago — and we’ll have to wait for 33 years more to see it again.Tellus, the mysterious planet humankind still have so much to learn about. For a long time, Earth was the only planet quietly traveling its circular orbit around the center of our Solar System, the Sun. Our solar system was generally a pretty stable place. Jupiter, Saturn, Mars, and other planets — they all acted in a predictable way, always the same orbits. Until some time ago something unexpected happened — another planet entered the Earth’s orbit.

Gold Isn’t Rare Like We Thought

While choosing the best metal to use for goods exchanging, our ancestors considered many different types. Gold seemed to be a good choice since it’s resistant to corrosion, and you can melt it over a flame, which makes it easy to stamp it as a coin or work with it in any other way. Gold is not that rare but is not easy to find and extract in larger amounts with pre-industrial technology. Geologists believe most of the Gold on our planet came from space with meteorite storms more than two billion years ago. It’s one of the densest metals on our planet, and humans have mined around 180,000 tonnes of it by now. If you want to tell if the diamond you’re holding is real or fake, breathe out on it. The genuine diamond will remain transparent, while the fake one will get foggy.

But, you notice another athlete running as quickly as you. You notice a puddle ahead of you and jump over it. You jump so far and so high it feels physically impossible.

Most Expensive Thing on Earth Takes Billions of Years to Make

Most Expensive Thing on Earth Takes Billions of Years to Make

The most expensive stuff in the universe — yeah, grandiose — is called anti-matter. Its existence was first theorized in 1930, when the electron was discovered. Scientists thought it might mean the exact opposite should exist too, and they called this hypothetical particle “positron.” Later, antipodes of other elementary particles, protons and neutrons, were proven to exist as well.When a particle and its evil twin collide with each other, they disappear, releasing literal tons of energy — 10,000 times more than a nuclear reaction does. But there’s a catch: it takes about 100 billion years to create just 1 g of anti-matter, and it can only be created using the Large Hadron Collider. That’s why the cost of this substance is about $62 trillion bucks. And we’re not even close to getting that much!Throughout the entire history of space observation, only two objects from another star system, or maybe even another galaxy, have entered our Solar System. The first one was the Oumuamua asteroid, discovered in 2017. The second was Borisov — a comet found in August 2019. The cloud of dust that surrounds it allows scientists to learn more about substances that may have come to us from another galaxy.

Asteroids flying around is sometimes like a fierce game of dodgeball where you never know when some of them can go in your direction. So we can just track the situation and hope for the best! To figure out the risk, scientists from different organizations have to study the positions and paths of the asteroids that come close to our planet, especially those that are at least 0.6 miles wide. And the good news is that none of these asteroids will probably hit us for at least the next 1,000 years. Phew!

This fly is tiny [0.08 to 0.23 inches long], but it’s still Antarctica’s largest terrestrial bug.

When we say ‘extinction’ — say it with me: “extinction” — we usually think of dinosaurs that went for lunch with a humongous asteroid and wiped out from the face of Earth. We don’t think of ourselves possibly going away in the near future. But what we forget is that there have been five mass extinctions that our planet witnessed in the last half a billion years, not just one. And we can be nearing the sixth one, where one of the species to possibly disappear are humans. The first great mass extinction came about 440 million years ago, in the — Period. Back then, life was mostly thriving in the oceans and along the coastlines. Biodiversity was great at the time: there were thousands of different species. Trilobites, sea scorpions, and all kinds of weird-looking mollusks and even fish — you name it, Ordovician had it.

Have you ever seen a skyscraper that can change its shape? The creators of the F&F Tower in Panama City had a concept and only $50 million, which isn’t a lot in skyscraper money. So, they couldn’t afford a mistake, and they finished a concrete structure with the 39 upper floors rotating 9 degrees around an axis from the first attempt without spending any extra time or materials. Dubai’s Rotating Tower will look different every time you see it once it’s finished. Each of its 80 floors will rotate 360 degrees individually around the center of the building. The lucky residents will be able to control that rotation, which means they can choose their view from the window. A complete lap should take about 90 minutes. And no, the tower won’t be a huge waste of electricity — it will produce its own energy! Wind turbines between the floors will drive the rotations.

Did you know that there’s an astronomical object in which space and time actually swap places? How does it work? And what exactly does “swapping space and time” mean? Well, let’s figure it out. Imagine that you’re on a spacecraft. The vehicle can only move straight. Your path leads to some inevitable point, and you have no idea what lies ahead. You can only hope that it won’t be too bad. Meanwhile, everything around you is complete madness. A chaotic collage of many historical events. What do you see? Ancient humans and dinosaurs? The birth of the universe? A... future? Who knows. That’s what the universe would look like if we swapped time and space. And, theoretically, this is what you’d see if you fell into a black hole and somehow were able to survive. But how is something like this even possible?

The largest planet in the Solar System is a gas giant, which means it’s made up mostly of gases. Due to the pressure and temperature differences, these gases separate into layers. This creates those red and white bands that can be clearly seen from Earth.

Did you know that humans are real space people? You were born in Space. Heck, even I was born in Space. We all were born in Space! But for humans to be here on Earth, so many conditions have to be precisely correct that it is highly improbable that we even exist. But we do. First, we — and any other space creatures who might be out there — have to live on a planet orbiting a yellow-ish white star, not a red star or a blue star. Not a blue star because they burn out too quickly — in a few million years — there wouldn’t be time for evolution to do its relatively slow magic and produce intelligent beings. Blue stars also tend to swell up and turn red — when they collapse and explode! It makes it highly unlikely that any civilization could prosper near a blue star.

Ah, yes. February 14, 2000. Just a regular Valentine’s Day, some flowers and some candy, the beginning of the new millennium, and... A good day to make history. NEAR Shoemaker (which stands for Near-Earth Asteroid Rendezvous) spacecraft, launched in 1996 [February], finally got a date with asteroid 433 Eros. It wasn’t about swiping right but going around Eros and completing the first soft landing on an asteroid ever.NEAR almost didn’t make it there, because an engine misfire from 1998 brought it into the wrong trajectory, and it missed the target. Yet, engineers decided to let NEAR do the circle around the Sun for one more year — and it eventually made it.NEAR Shoemaker was created to find, target, and stalk some smaller space objects for around a year and collect important data about them. This spacecraft got more than 160,000 pictures of the asteroid’s surface which helped with research in the years to come — before that, some scientists took asteroids for just some random flying piles.
