So time travel is real. Actually, you’re traveling through time right now. With every second of this article, you move one second into the future. Hehe. But there’s one person on Earth who has managed to time travel a little further into the future, 0.02 of a second. And that’s not the limit. Meet Sergei Krikalev. He’s an astronaut who spent 803 days, 9 hours and 39 minutes on the International Space Station. That’s the key to his time travel.

Dark, ever-hungry monsters live all across the Universe. They’re born when massive stars blast into space. Black holes as heavy as Earth are just as large as a ping pong ball. They don’t have a surface, but their gravity is so strong even light can’t escape it. Black holes don’t have physical boundaries like a membrane either. The event horizon, which is closest to a typical boundary, is a threshold which, after passing, you can’t get out. For a star, running into a black hole normally ends in a spectacular light show and its destruction. Just one star that astronomers know of managed to survive an encounter with a black hole as heavy as 400,000 Suns. It happened in a galaxy about 250 million light years away from Earth. Astronomers with really powerful equipment noticed bursts of X-rays that raged in space every nine hours. They thought they must be mayday signals from a star trapped by a cosmic abyss.

About 8 billion inhabitants of planet Earth found the same terrible news in one day. Someone saw it on TV. Others heard it on the phone while scrolling through social media or listening to music. Some witnessed this news in a dream while sleeping. Someone’s voice said it in all languages to ensure everyone understood it. “I have good and bad news for you. Let’s start with the bad news. You’re all characters in YouTube videos in which your planet gets into a situation where the Moon breaks in half. For the audience, it will be a hypothetical story. But for you, these events will become a reality. The good news is that... I was joking. There is no good news. But don’t worry, the apocalypse won’t start on your planet. Maybe just a little bit. Have a nice day.”

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.

Jupiter is the largest planet in the Solar System. More than 1,300 Earths could fit inside this gas giant. It’s also two and a half times more massive than all the other planets of the Solar System — combined! But if you think this is mind-boggling, I’ve got some great news for you! Very recently, a team of astronomers has discovered a much, much bigger planet with the help of the Subaru Telescope and the NASA Hubble Space Telescope.It’s a Jupiter-like protoplanet orbiting a very young star called AB Aurigae. 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.

It all started with a minor change on our planet. At first, people noticed the Moon had become brighter and a little bigger. But nobody paid attention to this. The Moon affected tides all over the world. The water flooded the beaches, but it wasn’t a tragedy. A lot of fish came close to the shores. People found giant squid, anglerfish, and other creatures next to the coast, although they usually live in the dark depths. New, stranger things happen every day. Birds no longer fly to the south in winter. They gather in huge groups flying around cities with no purpose. The Moon used to help them navigate in nature, so they can’t figure out which way to fly anymore.

Now, as much as we love epic space battles with blasters cutting through the black void and causing cheerful booms, that’s not exactly what happens when something explodes in the big black. Space is basically a vacuum, meaning it has no oxygen. And oxygen is an essential part of any process of burning we have here on Earth. You might argue that stars can burn and explode into supernovae, but that’s not exactly true either.

Astronomers have recently found a strange object far away from Earth. It disappears every two minutes and sends out waves of radio noise three times in one hour. It was first seen by a student named Tyrone O’Doherty while he was looking at the sky in his home country, Australia.This space object appears to be different from anything else we’ve seen before in space. Because of their “calculated” movements, scientists call these types of objects “transients.” Turns out, they are not that rare to find. When scientists study transients, most of the time, they look near a big star or near the things it leaves behind after it goes out.

Hey, space buffs! Just how well do you know our Solar System? Guess the planet: it’s more than twice as massive as all the other planets combined. It’s covered with striking swirls and stripes — which are actually windy clouds of cold ammonia and water, floating in an atmosphere of hydrogen and helium. Still no clue? Then look at this! It’s the infamous Great Red Spot — a giant storm larger than our home planet that has been raging for hundreds of years. Right you are! This cloudy world is Jupiter! And the main question is, “Is this planet our enemy or friend?” NASA’s Juno orbiter is exploring this gas giant at the moment, sending us tons of useful data. Jupiter is so big that 11 Earths could fit across its equator. If our planet was the size of a grape, Jupiter would be a basketball! The gas giant is the fifth planet from the Sun, orbiting around 484 million miles away.

Have you ever wondered what stars look like in galaxies far, far away? Researchers can generally only see the brightest stars, so with the data they managed to collect, they simply thought these stars were similar in size and weight to the ones we have in our own galaxy. It’s hard to explore the space around us though. When they study stars in other galaxies, it’s like they’re trying to see a tiny ant crawling on a leaf. Not easy, but some new fancy models allowed them to find more information about distant galaxies. They used a big telescope to study light from 140,000 different galaxies, some of which are billions of light-years away from us. They realized stars in distant galaxies are mostly larger than those in our Milky Way. They’re heavier too.

Okay so you’ve seen the movies and read the books on time travel. Most of them tell stories about entering some futuristic boxes — and in the blink of an eye, you’re in some different epoch. For now, this is just sci-fi. But there are ways to make time travel possible — at least theoretically. We just don’t have the technology figured out yet.For starters, time travel to the future could be achieved by traveling at high speeds. But not just “getting a ticket on the super highway” kind of speed. This is based on Einstein’s theory of special relativity. It explains that time slows down for objects that move at really high speeds. And the good news is scientists have already tested this theory, and it looks promising. They did it with the help of two identical clocks. One was placed on a jet, and one stayed on the ground.

So, Mars has two moons — Phobos and Deimos. And, apart from the bizarre shape, there’s nothing remarkable about them... Except for one thing. Not so long ago, scientists discovered a strange phenomenon on the surface of Phobos. And they still can’t find any explanation for it. What is this phenomenon? And what does it tell us about the history of our Solar System? Let’s find out. American astronomer Asaph Hall discovered Phobos and Deimos back in 1877. Do you know that all the planets in our Solar System are named after Greek and Roman deities? For example, Mars, or Ares, is the famous deity of war. That’s why the satellites of this red planet were named after the sons of Ares — Phobos and Deimos.

This planet must have been smaller than ours, the size of Mars. And the collision itself probably happened around 4.5 billion years ago.

But first things first: you take a moment to remember everything you know about the fourth planet from the Sun. It’s the last of the inner planets — those are the planets that lie within the asteroid belt. They’re also called terrestrial since they’re made up of rocks and metals. The atmosphere of Mars is much thinner than Earth’s. It contains 95% carbon dioxide and a mere 1% of oxygen. In other words, don’t even think about pulling off your helmet!

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?

On average, Earth’s waters rise by 14 hundredths of an inch each year, and sometimes I feel like, you know, getting some floaties. So we can’t help but wonder what if we end up living underwater? We now have evidence that humans could adapt to that. The Bajau — a group of people living in South-East Asia — have evolved to have enlarged spleens. The spleen is the organ that stores oxygen-rich red blood cells. When these cells are released into the bloodstream, they enable divers to hold their breath underwater for longer periods of time. This allows the Bajau people to free dive to depths of up to 230 feet!

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.
