Is there an alien civilization next door? It’s quite possible. Proxima Centauri b is in the habitable zone and is pretty similar in mass to the Earth. NASA's telescope might have detected proof of artificial lights coming from that planet. What is it? An alien city or maybe lights from their vehicles? Or some sort of signal they might be sending us?

To many of us, the concept of flying cars is synonymous with something futuristic, just like Sci-Fi architecture or silver jumpsuits. But what if we could not only create flying cars but also send them into space? With no oxygen and no water, there's no chance that a flying car would rust. But how fast could such vehicle move in space?

Did you know that the most intelligent people are usually the least happy individuals among us? If you can relate to most of the signs of a smart person we’ve put together, you must have a high IQ, but might be rather unhappy in life. Follow professional advice of leading experts in psychology to transform your life in a positive way.

The sun has a regular heartbeat, and we call it the solar cycle. But it's been a bit of a drama queen lately because it's experiencing a "solar minimum." Translation: fewer sunspots and less solar activity. Solar flares and sunspots usually spice things up, but they've been pretty scarce lately. Scientists have noticed that the Sun's magnetic field is getting all tangled up. This could mean some interesting magnetic storms on Earth, so keep an eye out for crazy auroras! Some folks are even suggesting this could be the start of a "Grand Solar Minimum" where the Sun chills out and we see cooler temperatures on Earth. So, keep those shades handy because the Sun's unpredictable behavior is making the space news headlines!

We've all been there – the heart-wrenching moment when your favorite snack takes a nosedive onto the floor. But wait up; science says you've got about a five-second grace period to scoop it up and declare it safe to munch, right? The whole "5-second rule" might not be legit science, but if it's a clean surface, and you're feeling brave, why not give it a go? Just remember, no amount of fast thinking can save a snack from a sticky floor or a pet-hair party, so trust your instincts and rock on with your impromptu floor feast.

It was a mining disaster in Chile that left them stranded, and the whole world held its breath. They had to ration food and water, and communication was basically non-existent. But they didn't give up. Rescuers worked tirelessly, and when they finally pulled those miners to safety, it was like a miracle. It's a story of human resilience and the incredible will to survive against all odds for a whole 69 days.

The Moon is always in the sky and we can see it as it reflects the Sun's light. When and where you see the Earth's natural satellite depends on the phase of the Moon. But what if you looked up into the sky and saw something different? What if the Moon turned into a giant disco ball? Would day and night seem like an endless disco party? Let's imagine what it'd be like...

What SIM does stand for? It means subscriber identity module or subscriber identification module. The first SIM card in the world was developed in 1991 by the German company Giesecke & Devrient. They sold 300 SIM cards to Radiolinja, a Finnish wireless network operator. In 1992, they sold the first GSM mobile phone with a SIM card; it was a Nokia 1101. Today, it’s hard to find a person who’s never used a SIM card – over 7 billion gadgets around the world use them to make calls, send SMS and surf the web.

How does a mechanical watch work? Unlike a quartz watch, it doesn't get its energy from a battery. Then, where does it receive its power from?

What are those white lines on your smartphone? How do you separate yolks from whites with an empty plastic bottle? And how can duct tape help you to open tough lids? There're so many objects surrounding us we know very little about. And the more we know, the more useful these items can be. Let's take a look at the most unusual secrets hidden in everyday things.

Nowadays you can get almost anywhere you want by plane. But there are places on Earth over which planes can't fly. They are restricted zones you can’t enter for security or secrecy reasons. Let's explore some of them and find out, why it's forbidden to fly over these places... One of such zones is Disneyland and Disney World. It's forbidden to fly over the theme park without a special waiver and the restriction goes 3,000 feet above sea level. Another place protected from helicopters is a huge hole in Earth's surface. The giant pit is a diamond mine and it messes with the flow of air, creating a vortex that helicopters might get in... How's it possible?

The ocean covers more than 70 percent of the surface of the Earth. It's hard to imagine our planet without the blue color of the oceans. But what if all the water in the oceans disappeared? Let's see how life would change if the oceans dried up. The landscape would definitely be spectacular. People would have finally found out the secrets of the ocean depths. We'd see that the bottom of the ocean is covered with mud volcanoes, seamounts, canyons and cold seeps. But what'd happen to the oceans creatures?

Why do we say “OK”? It’s hard to believe there was ever a time when some words didn’t exist. Had you been around before 1839, for instance, you wouldn’t have had a clue what OK means because OK wasn’t a thing yet! It's easily one of the most widely-used expressions around the world. It isn’t confined to one region, language, or even purpose! You use it to show that you got the message, like when your boss says, “Hey, I need you to send me a copy of that report” and you reply, “OK!” Yet if you think that something was just mediocre, you say, “Eh, the movie was OK.”

There are some things we use or do all the time without knowing the true reason behind them. Instead of taking them for granted, find out what the most curious facts about everyday objects you never had time to Google. Why are plane windows rounded? Why are sneakers called sneakers? What is the right way to peel a banana? You’ll be surprised to find out the answers to these questions. Did you think croissants were from France? If yes, then you’re not alone. Given the French name, it’s obvious that most people would think they originated in France. But that’s not true. Croissants actually hail from Vienna, Austria. Trailers were originally shown at the end of a feature film screening, but the practice didn’t last long because patrons would leave the theater soon after the films ended. Barbie’s full name is Barbara Millicent Roberts. And, she doesn’t come from Malibu, but a fictional place called Willows in Wisconsin instead. No one can imagine any electronics to be associated with water. But the USB logo has a subtle link to water. It is modeled after the trident of Poseidon, the god of the Sea and other waters.
