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.

An amazing video published on youtube by National Geographic. How deep is the ocean (on average) and the Mariana Trench, the deepest part of the world’s oceans?

Our home planet, Earth, is the third of the four smaller inner planets (Mercury, Venus, Earth, and Mars). It is also the only planet in our solar system known to harbor life. Here are some interesting facts about Earth in the Solar System.

In 1950, the Italian physicist Enrico Fermi was chatting with his colleagues at the Los Alamos National Laboratory(1). They talked about the recent rise in UFO reports, then the conversation shifted to other subjects. But during the lunch, Fermi suddenly asked: “Where is everybody?”. He was talking about the extraterrestrial life, especially intelligent life. He made some calculations on the probability of Earth-like planets, the beginning of life, the probability of intelligent life and high technology and concluded that we ought to have been visited long ago and many times over.
But, there is no reliable evidence aliens have visited Earth and we have observed no intelligent extraterrestrial life with current technology nor has SETI found any transmissions from other civilizations. The Universe, apart from the Earth, seems “dead”.
So, where is everybody?

You must watch this! An amazing video by the filmmakers led by Julian Tryba: in May 2015, over the span of three weeks, they traveled in the Southwest of the United States (3,000 miles through Utah, Arizona, Nevada, and California) and filmed timelapses of several strikingly beautiful landscapes. Then they spliced the films together to create this wonderful video, a strange day-night world.

A nice interactive webpage by the BBC – The British Broadcasting Corporation: how you and the world have changed since you were born? You’re simply entering your birth date, gender, and height; selecting units (metric or imperial/US) and then watching how our planet (and you) has changed in your lifetime.

In two different locations in the coast of Hawaii, scientists have observed unusual interactions between bottlenose dolphins and humpback whales as dolphins “rode” the heads of whales: the whales lifted the dolphins up and out of the water, and then the dolphins slid back down. In the video published by the American Museum of Natural History, the two species seemed to cooperate in the activity, and neither displayed signs of aggression or distress. Whales and dolphins in Hawaiian waters often interact, but playful social activity such as this is extremely rare between species.

Thousands of (more than 9600) photos taken by the astronauts during the Apollo Program (1966-1972) now on the popular image and video hosting website Flickr. Network and administrative data systems specialist and Project Apollo Archive‘s creator Kipp Teague recently updated new and unprocessed versions of original NASA photo scans to the image sharing site.

You can see all the archive on the Project Apollo Archive page on Flickr. The photos are taken by the Sweden-made “Hasselblad” cameras from the Earth, from the Lunar orbit and on the surface of the Moon by astronauts with their chest-mounted cameras.
No, no no, and again: no! The Earth would NOT look like this without water. Please stop sharing this nonsense.

Here some numbers: the Earth has a diameter of about 12,735 kilometers (on average). The highest point on Earth is the top of Mt. Everest, at 8.85 km. The deepest point on Earth is the Mariana Trench, at about 11 km deep. Make the calculations and you can see, the Earth definitely would NOT look like below without water:
