In the middle of the South Pacific Ocean, there’s a location called “Point Nemo”. It’s not a place that humans live – in fact, there is no land there – not an island, not even a small rock. It is actually the remotest place from any human civilization you can find on Earth. It lies at least 2,688 km (1,670 mi) from the nearest land. It is also called “Oceanic pole of inaccessibility”.Notes 1

Where native large crocodilians and humans live close to each other, crocodile attacks on humans occasionally occur. In fact, only 6 out of 22 crocodilian species are considered dangerous to adult humans.Notes 1 And in those six species, only individuals 2 meters (6.6 feet) and longer in length are capable of killing adult humans. Two species, which are also the largest and most aggressive, saltwater crocodile and Nile crocodile are well-known reputation for preying on humans. These two also have the most documented cases. Each year, hundreds of people die of either Nile or saltwater crocodile attacks. The mugger crocodile, which can be found throughout the Indian subcontinent and the surrounding countries, also very dangerous to humans, killing many people in India every year. Despite the American crocodile is considered to be less aggressive, a few (unverified) fatally attacks reported. Also, species/individuals smaller than 2 meters can inflict painful and dangerous bites on adult humans and they even capable of killing children. Even then, according to the Worldwide Crocodilian Attack Database most interactions between crocodiles and humans are non-eventful.

Crocodiles are aquatic reptiles, and among the most feared carnivores on Earth, because of their size, big powerful jaws and aggressiveness. They are so successful predators – once they were living alongside the dinosaurs. After the Chicxulub impact, which happened around 66 million years ago, the non-avian dinosaurs were gone but crocodiles were managed to survive. Here are top 20 amazing crocodile facts about these fascinating beasts.

The billionaire founder of SpaceX, Elon Musk has revealed a new plan to colonize Moon and Mars with giant reusable spaceships. He provided an update on their Mars colonization plan at the International Astronautical Congress (IAC)Notes 1 in Adelaide, Australia this week. Musk plans sending 1 million people to Mars using BFRNotes 2, and “making life multiplanetary”. He has highly ambitious plans, like launching and landing at least two uncrewed cargo ships on Mars as early as 2022.

Birds (Aves) range in size and weight from the 5 cm (2 in) and 1.6-2 grams bee hummingbird to the 2.75 m (9 ft) and 104-156 kg (229-344 lbs) ostrich. Here are the top 15 largest birds in the world (by body weight).
Birds form one of six basic animal groups, with the others being amphibians, fish, invertebrates, mammals and reptiles. They are endothermic vertebrates, characterized by feathers, toothless beaked jaws, a high metabolic rate, a four-chambered heart, and a lightweight but strong skeleton. They reproduce by laying of hard-shelled eggs (eggs fertilize inside the female). The fossil record indicates that birds are the last surviving group of dinosaurs. So, they are also termed avian dinosaurs.

You may have heard it has been said that if our planet were shrunk down to the size of a billiard ball, it would be smoother than it. In other words, the Earth is smoother than a billiard ball. Is that true?

Identifying the largest dinosaurs ever lived isn’t an easy task, because it’s very rare to unearth a complete fossil. Furthermore, only a tiny percentage of these amazing animals ever fossilized, and most of these “lucky” bodies will remain buried underground forever. So, we may never know exactly what dinosaur was the biggest (or the tiniest) ever.
Despite this fact, size always has been one of the most interesting aspects of these prehistoric animals. There are extreme variations in their size, from the tiny hummingbirds, which can weigh as little as three grams, to the titanosaurs, which could weigh as much as 70 tonnes, or even more.
Here are some of the largest dinosaurs ever lived.

You have probably heard references made to the “dark side” of the Moon – there’s even a Pink Floyd album with that name. But, in fact, there’s no “dark side” of the moon. Because it is not illuminated by the Earth, it is illuminated by the Sun. All the surface of the moon lit by the Sun as the Moon rotates.

In the last few years, a series of photos circulating over the Internet via email and online, usually with the title of “Man Who Befriended a Great White Shark”, showing close encounters between a man and a great white shark. The sites who publish these photos (and sometimes PowerPoint presentations) claim that an Australian fisherman named Arnold Pointer once freed a great white shark from a fishing net, and the shark has followed him around ever since.

Our civilization emit so much CO2 into the Earth’s atmosphere, that only planting trees is not enough, according to a new study.
