People are shouting and waving their hands in the auction room. The presenter can’t calm everyone down because the lot on the table is the most expensive dirt in the world. Its price is about $9 billion. But it’s really hard to imagine its real value. Because it’s dirt from Mars. It’s so expensive because it’s going to take one decade, billions of dollars, and three space missions to deliver the dirt here, to Earth. And we’ve already started the first mission. On July 30, 2020, a single-use Atlas V rocket was launched from Earth’s surface toward Mars. The cost of launching such a rocket is about $109 million. The rocket carried the Perseverance rover and Ingenuity drone. The flight took about seven months. On February 18, 2021, the rocket finally reached its destination. The landing module carrying the rover and drone was launched into the atmosphere of Mars. The robotic heroes traveled inside a capsule faster than the speed of sound. Underneath, the capsule was protected by a heat shield to keep its valuable cargo from burning due to high temperatures.

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 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.

Recently, Chinese scientists discovered something interesting on the Moon... An unusual crystal. Moreover, they found out that this crystal contains an element that can literally replace nuclear fuel! Let’s find out more. The composition of the Moon has long remained a mystery to us. Half a century has already passed since the Apollo mission. Unfortunately, we haven’t traveled to the Moon much since then, so it’s not surprising that it’s not so easy for us to study it. But recently we’ve made a breakthrough in this area! In December 2020, Chinese scientists sent a Chang’e-5 probe to the Moon. The mission was named after the ancient Chinese deity of the Moon, Chang’e. Quite poetic, isn’t it?

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.

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.

Do you know that Leonardo da Vinci created a drawing of a mechanical robot in knight’s armor in 1495? According to the detailed plan, this knight could move and swing a sword thanks to an internal mechanical system consisting of ropes and gears. Whether Leonardo built this robot is unknown, but in 2002, one robotics engineer created this mechanical knight. And do you know what the first real robot looked like? It wasn’t a person in a cardboard robot suit. It was a real machine powered by electricity. It looked like a large box with an arm sticking out of it — like a smaller version of a crane. An inventor from Kentucky, George Devol, created it in the 1950s. He patented his invention and called it “Unimate.” The box with a mechanical arm was used in a TV show. The robot hit a golf ball into a cup, poured a drink into a mug, and impersonated a music band. People were delighted, but the invention didn’t bring George Devol money.

Imagine stepping out of your spacecraft and setting foot on the surface of the Moon. Under your feet, the ground is covered with a fine material that looks like powder. That’s lunar dust. You look around and take a lungful of fresh air. It smells very different from the air on Earth but still nice... Unfortunately, this is a highly unlikely scenario. And one of the reasons is that the Moon has almost no atmosphere. Earth’s natural satellite is too small — less than 2% of our planet’s mass. That’s why it doesn’t have a magnetic field strong enough to keep an atmosphere. But even if the Moon had it, solar winds would immediately pull it away.

Back in the late 1960s and early 70s, it was the first time in our history we set foot on a surface that wasn’t Earth. During the several trips to the Moon in the Apollo program, astronomers brought back some rocks and soil to study.

They didn’t do anything at first, aware that decades into the future, they’d have more advanced equipment to conduct these studies. The researchers named the lunar soil “regolith” and used the seeds of a particular plant called blah-bah-blah-baa — you can read it here [Arabidopsis thaliana] which is found in Asia, Europe, and parts of Africa. It’s similar to such veggies as cauliflower, Brussels sprouts, and broccoli. Yum.

It’s a clear night, and you are outside looking at the stars. The Milky Way alone seems overwhelmingly huge. You check on your phone and discover that the galaxy you’re in at this exact moment is 100,000 light-years wide. For scale, 1 light-year is already a very long distance. For example, it takes 4.2 light-years to go from Earth to Proxima Centauri, which is the closest star to our planet other than the Sun. So 100 thousand light-years is way more than we normal humans can fathom. And that’s just one galaxy. There’s a whole lot more out there.
