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.

What if Mars still had liquid water on its surface and a thick atmosphere filled with clouds, like Earth? How would it look like? Software engineer Kevin Gill of JPL (NASA’s Jet Propulsion Laboratory) wondered this and prepared an image using data from NASA’s Mars Reconnaissance Orbiter (MRO)(1) and Mars Orbiter Laser Altimeter (MOLA)(2). The result is stunning!
Gill picked an arbitrary sea level and used GIMP (a free and open-source raster graphics editor used for image retouching and editing) to paint the features onto the satellite images using these measurements.

Like crocodiles, snakes also suffer from a prevalence of “big fish” stories and over-exaggeration in the internet era. In fact, it is very difficult to measure how large actually a snake is, especially if it’s really big. So, how big are the largest snakes actually?

If you search for the fastest land animals on the Internet, you will find many “fastest animals” lists, most of them are popular “top list” sites. But, in fact, there is a tendency to overestimate the speed of fast animals. Even the speed of the world’s fastest land animal, cheetah’s speed is usually highly overestimated.
Measuring an animal’s speed is a very hard task, and very few of them were properly authenticated. Some of them are really fast, that’s true, but what is the exact number? This information is usually not measured correctly.

A year after returning its first image, NASA’s EPIC camera, a four megapixel CCD camera and telescope attached the Deep Space Climate Observatory (DSCOVR) shows us an entire year of Earth from almost one million miles away. The result is the amazing video below.

The “Seven Wonders of the World“, describes seven great constructions known in the Hellenistic period – that’s why they are also known as the “Seven Wonders of the Ancient World”. In fact, in the Hellenistic era, each famous traveler had his own version of the list, but the best known and earliest surviving was from a poem by Greek-speaking epigrammist Antipater of Sidon, which he described in a poem composed about 140 BC:
“I have set eyes on the wall of lofty Babylon on which is a road for chariots, and the statue of Zeus by the Alpheus, and the hanging gardens, and the Colossus of the Sun, and the huge labor of the high pyramids, and the vast tomb of Mausolus; but when I saw the house of Artemis that mounted to the clouds, those other marvels lost their brilliancy, and I said, ‘Lo, apart from Olympus, the Sun never looked on aught so grand.'”
But, in fact, all “seven wonders of the world“ existed at the same time for a period of less than 60 years. And now, only the Great Pyramid of Giza still in existence. All the others somehow gone.
If Antipater of Sidon was living in the more recent times, say 19th century, he probably would prepare a very different list. Here are the alternative seven wonders of the world that still exist today (with the images and videos):
