In 2006, Planet Earth, the British television series produced by the BBC Natural History Unit “has changed our view of the world”. It was the first nature documentary series filmed in high definition. It took five years in the making and it was the most expensive nature documentary series ever commissioned by the BBC. Now, ten years later, in February 2016, the BBC announced a six-part sequel had been commissioned, titled Planet Earth II. On October 2016, BBC released the new series’ trailer.

Earth is still the only planet we know where water can exist in liquid form on the surface and the water is vital for all known forms of life. Rain brings life: it is a major component of the water cycle (also known as the hydrologic cycle, the continuous movement of water on, above and below the surface of the Earth) and is responsible for depositing most of the fresh water on the Earth. Here are the top ten wettest places on Earth.

Earth is a blue marble in the space: the water, gives our planet its blue color: about 71 percent of the Earth’s surface is water-covered. There is roughly 326 million cubic miles (1.332 billion cubic kilometers) water on the Earth’s surface. Almost 97% of that water is salty (ocean water). But where all that water came from?

Alex Kuzoian and Jessica Orwig of Business Insider has prepared a video titled “Here’s why Elon Musk wants to colonize Mars”. In the video, we see some reasons why we should colonize Mars someday.

We are living on a tiny life-bearing rock, an oasis, in a large, very large and hostile desert called “Universe”. The universe is big, really big, in fact, even our solar system is shockingly large compared to Earth. But again, our brains have problems dealing with the big numbers and the large objects.
Jacqui Frank of Business Insider has prepared video comparing our planet with large objects (and distances) in the Universe. These amazing to-scale visuals will help to recognize how small (and fragile) our planet is.

The title describes itself. Artist and designer Josh Worth has created a great web page which is actually a scaled model of our solar system. He scaled the Moon to only one pixel (the radius of the Moon is 1,737 km / 1079.322 mi) and put the planets and other objects like the Kuiper Belt accordingly.

Since the human brain cannot deal with the really large numbers, it is a good way to understand how big is our Solar system actually (it is really big!).
Our planet is getting warmer every year, and the horrible fact is, global warming is accelerating. As a natural result, the glaciers are melting at an increasing speed.
Almost 10% of the world’s land surface is currently covered with glaciers, mostly in places like Greenland and Antarctica. The amount of water locked up in ice and snow is only about 1.7 percent of all water on Earth (332,500,000 cubic miles, or 1,386,000,000 cubic kilometers), but the majority of total freshwater on Earth, about 68.7%, is held in ice caps and glaciers. And if all land ice melted the seas would rise about 70 meters (about 230 feet).
What if all these ice melted? What would Earth look like? Alex Kuzoian of Business Insider prepared a video showing the effects of the global melting, and if it happens, “this would dramatically reshape the continents and drown many of the world’s major cities.”

Earth has a mild climate, which enables the life on its surface. But there are some places exist which probably you won’t want to be there, at least uncovered. Here are the hottest and coldest places of our planet.

Our old planet, the Earth is 4.54 billion years old. In fact, the human mind can no longer make any sense of large numbers like that. Numbers like 1, 2, 14, 20, 50 are all quantities that we encounter quite frequently in our daily lives. And our brain evolved to conceptualize numbers like that: our ancestors saw two lions; they hunted five deer in one hunting party, the population of their tribe was 20, etc… But when the numbers are getting big, i.e. 1,000; 10,000… the problem begins: these numbers become increasingly difficult to conceptualize. Now, what happens when we try to conceptualize quantities like billions, like the Earth’s age? We can’t actually rationalize the immensity of such a big number. Because we haven’t a model of 4.54 billion that’s been compressed into something recognizable to the human mind.
To put this number into a perspective, Alex Kuzoian of Business insider prepared a beautiful video: you can watch Earth’s lifespan as the distance from Los Angeles to New York City. Along the trip, we see the formation of our Moon, the beginning of the life, the evolving of the multi-cellular organisms, and the rise and fall of the dinosaurs. Probably the most interesting part is that modern humans only evolved 175 meters (570 feet) from the finishing line of this journey. And the big jump to the first multi-cellular organisms.

Earth, the blue planet: the oceans combined with the atmosphere makes the planet look blue. So its color mainly comes from water. About 71% of the Earth’s surface is covered with water, in fact, Earth is still the only planet we know where water can exist in liquid form on the surface. Water is also vital for all known forms of life. But there are numerous places on Earth that receive rainfall less than even 0.76 mm annually. One place even receives absolutely no rainfall. Here are the top ten driest places on Earth.
