On this spontaneous camping trip, I took the train from the Netherlands to travel to Eastern Europe. For years already I have been intrigued to explore the rare wild areas in Europe. Stories about lush, still untouched forests. Are they really that wild? Stories about illegal logging and murdering of forest rangers. Stories about bears taking over towns.. …have brought me to Romania. Here I hope to get an idea of the dynamics between humans and nature in these vast landscapes, where we can still find some of the wild origins, of what the temperate zone would have looked like. Something that is not existent anymore in my home country. Let me share this camping trip with you guys! Enjoy! Thanks to Agent Green for their support and for using some of their footage!

In the late 17th century, French monarchs were expected to keep mistresses, and Louis XIV was no different. In fact, throughout his reign, he would go on to father over 12 illegitimate children. #LouisXIV #PrivateLivesOfTheMonarchs #SmithsonianChannel From The Private Lives of Monarchs: Louis XIV http://bit.ly/33Hpng2 Subscribe to The Smithsonian Channel: https://bit.ly/2FE6OSh Twitter: https://bit.ly/33lH712 Instagram: https://bit.ly/3iw9Iay Facebook: https://bit.ly/3kkVOZp

Exceptional People: Arm Fishing, Burning Soccer & Wildlife Hunting in Texas | Mavericks Unlimited On this episode of “Mavericks Unlimited,” we attempt catching huge fish with your bare hands – that’s “noodling”. The catfish weigh up to 30 kilos and will bite! But fish are not the only dangerous animals lurking in the muddy waters. In addition, we watch young boys playing football with a burning ball. Nothing out of the ordinary in Indonesia. Temperatures of more than 150 degrees and direct skin contact. Why would anyone do something like that? And finally we go safari hunting in the heart of Texas, where African animals not normally found in the US are kept to be shot by amateur hunters. ▬▬▬▬▬▬▬▬▬ Subscribe Free Documentary Channel for free: https://bit.ly/2YJ4XzQ Support us on Patreon: https://www.patreon.com/freedocumentary Facebook: https://bit.ly/2QfRxbG Twitter: https://bit.ly/2QlwRiI ▬▬▬▬▬▬▬▬▬ #FreeDocumentary #Documentary #MostExtremePeople ▬▬▬▬▬▬▬▬▬ Free Documentary is dedicated to bringing high-class documentaries to you on YouTube for free.

There’s a 13th zodiac sign? You ll also learn about Earth’s wobble on its axis and what “precession” is. Was the north star always the north star? We talk about the north star of ancient times and what the night sky will look like in the future. How does precession affect your zodiac sign? We explore how the current zodiac differs from when it was first invented. What is Ophiuchus? And is Cancer really the lamest constellation??? All that and more on another StarTalk explainer!

Here s a big mystery in astronomy: fast radio bursts. Brief shrieks of radio waves coming from space. What are they? Where do they come from? Astronomers have no idea.

What’s actually happening is that you’re tagging along as I learn more and more about new and cool things happening in the Universe. I dig into them like a badger hiding a cow carcass, and we all get to enjoy the cache of knowledge I uncover. Okay, that analogy got a little weird. Anyway, my point is. Squirrel! Fast radio bursts are the new cosmic whatzits confusing and baffling astronomers, and now we get to take a front seat and watch them move through all stages of process of discovery. Stage 1: A strange new anomaly is discovered that doesn’t fit any current model of the cosmos. For example, strange Boyajian’s Star. You know, that star that probably doesn’t have an alien megastructure orbiting around it, but astronomers can’t rule that out just yet? Stage 2: Astronomers struggle to find other examples of this thing. They pitch ideas for new missions and scientific instruments. No idea is too crazy, until it’s proven to be too crazy. Examples include dark matter, dark energy, and that idea that we’re living in a Stage 3: Astronomers develop a model for the thing, find evidence that matches their predictions, and vast majority of the astronomical community comes to a consensus on what this thing is. Like quasars and gamma ray bursts. YouTuber’s make their videos. Textbooks are updated. Balance is restored. Today we’re going to talk about Fast Radio Bursts. They just moved from Stage 1 to Stage 2. Let’s dig in. Fast radio bursts, or FRBs, or “Furbys” were first detected in 2007 by the astronomer Duncan Lorimer from West Virginia University. He was looking through an archive of pulsar observations. Pulsars, of course, are newly formed neutron stars, the remnants left over from supernova explosions. They spin rapidly, blasting out twin beams of radiation. Some can spin hundreds of times a second, so precisely you could set your watch to them. In this data, Lorimer made a “that’s funny” observation, when he noticed one blast of radio waves that squealed for 5 milliseconds and then it was gone. It didn’t match any other observation or prediction of what should be out there, so astronomers set out to find more of them. Over the last 10 years, astronomers have found about 25 more examples of Fast Radio Bursts. Each one only lasts a few milliseconds, and then fades away forever. A one time event that can appear anywhere in the sky and only last for a couple milliseconds and never repeats is not an astronomer’s favorite target of study. Actually, one FRB has been found to repeat, maybe. The question, of course, is “what are they?”. And the answer, right now is, “astronomers have no idea.” In fact, until very recently, astronomers weren’t ever certain they were coming from space at all. We’re surrounded by radio signals all the time, so a terrestrial source of fast radio bursts seems totally logical. About a week ago, astronomers from Australia announced that FRBs are definitely coming from outside the Earth. They used the Molonglo Observatory Synthesis Telescope (or MOST) in Canberra to gather data on a large patch of sky. Then they sifted through 1,000 terabytes of data and found just 3 fast radio bursts. Three. Since MOST is farsighted and can’t perceive any radio signals closer than 10,000 km away, the signals had to be coming outside planet Earth. They were “extraterrestrial” in origin. Right now, fast radio bursts are infuriating to astronomers. They don’t seem to match up with any other events we can see. They’re not the afterglow of a supernova, or tied in some way to gamma ray bursts. In order to really figure out what’s going on, astronomers need new tools, and there’s a perfect instrument coming. Astronomers are building a new telescope called the Canadian Hydrogen Intensity Mapping Experiment (or CHIME), which is under construction near the town of Penticton in my own British Columbia.

And has recently swiveled to point its one of these jets directly at us. Is this an intergalactic death ray of an alien civilization that has suddenly noticed us? Absolutely not, and there’s no danger at all. But it’s a pretty cool phenomenon anyway, and something we’ve never seen before.
