Visions of Eart by National Geographic



Not far from its Franklin Island colony, a lone Adélie punctuates the looping scrawl of penguin tracks across plates of Ross Sea pack ice. Some 2.7 million of the birds populate the Ross Sea region.

Eiffel Tower, Paris



The Eiffel Tower (French: Tour Eiffel, /tuʀ ɛfɛl/) is an iron tower built on the Champ de Mars beside the Seine River in Paris. The tower has become a global icon of France and is one of the most recognizable structures in the world.

Named after its designer, engineer Gustave Eiffel, the Eiffel Tower is the tallest building in Paris and one of the most recognized structures in the world.[1] More than 200,000,000 have visited the tower since its construction in 1889,[2] including 6,719,200 in 2006,[3] making it the most visited paid monument in the world.[4][5] Including the 24 m (79 ft) antenna, the structure is 325 m (1,063 ft) high (since 2000), which is equivalent to about 81 levels in a conventional building.

When the tower was completed in 1889 it was the world's tallest tower — a title it retained until 1930 when New York City's Chrysler Building (319 m — 1,047 ft tall) was completed.[6] The tower is now the fifth-tallest structure in France and the tallest structure in Paris, with the second-tallest being the Tour Montparnasse (210 m — 689 ft), although that will soon be surpassed by Tour AXA (225.11 m — 738.36 ft).



The metal structure of the Eiffel Tower weighs 7,300 tonnes while the entire structure including non-metal components is approximately 10,000 tonnes. Depending on the ambient temperature, the top of the tower may shift away from the sun by up to 18 cm (7 in) because of thermal expansion of the metal on the side facing the sun. The tower also sways 6-7 cm (2-3 in) in the wind.[7] As demonstration of the economy of design, if the 7300 tonnes of the metal structure were melted down it would fill the 125 meter square base to a depth of only 6 cm (2.36 in), assuming a density of the metal to be 7.8 tonnes per cubic meter. The tower has a mass less than the mass of the air contained in a cylinder of the same dimensions,[8] that is 324 meters high and 88.3 meters in radius. The weight of the tower is 10,100 tonnes compared to 10,265 tonnes of air.



The first and second levels are accessible by stairways and lifts. A ticket booth at the south tower base sells tickets to access the stairs which begin at that location. At the first platform the stairs continue up from the east tower and the third level summit is only accessible by lift. From the first or second platform the stairs are open for anyone to ascend or descend regardless of whether they have purchased a lift ticket or stair ticket. The actual count of stairs includes 9 steps to the ticket booth at the base, 328 steps to the first level, 340 steps to the second level and 18 steps to the lift platform on the second level. When exiting the lift at the third level there are 15 more steps to ascend to the upper observation platform. The step count is printed periodically on the side of the stairs to give an indication of progress of ascent. The majority of the ascent allows for an unhindered view of the area directly beneath and around the tower although some short stretches of the stairway are enclosed.

Maintenance of the tower includes applying 50 to 60 tonnes of paint every seven years to protect it from rust. In order to maintain a uniform appearance to an observer on the ground, three separate colors of paint are used on the tower, with the darkest on the bottom and the lightest at the top. On occasion the colour of the paint is changed; the tower is currently painted a shade of brownish-grey.[9] On the first floor there are interactive consoles hosting a poll for the colour to use for a future session of painting. The co-architects of the Eiffel Tower are Emile Nouguier, Maurice Koechlin and Stephen Sauvestre

The Sahel 2



Swallowing all but the tallest trees, dunes have buried cropland near the city of Goudoumaria, where a herder follows goats in search of forage. Reduced rainfall has withered vegetation and dried up wells in parts of southern Niger, forcing villagers to move. The Sahel experienced droughts in the 1970s and '80s, and although rainfall has increased since the 1990s, a decades-long dry spell continues.

Japan Timelapse

Japan (日本 Nihon or Nippon ? , officially 日本国 Nippon-koku (help·info) or Nihon-koku) is an island country in East Asia. Located in the Pacific Ocean, it lies to the east of China, Korea and Russia, stretching from the Sea of Okhotsk in the north to the East China Sea in the south. The characters that make up Japan's name mean "sun-origin", which is why Japan is sometimes identified as the "Land of the Rising Sun".



Japan comprises over 3,000 islands,[5] the largest of which are Honshū, Hokkaidō, Kyūshū and Shikoku, together accounting for 97% of land area. Most of the islands are mountainous, many volcanic; for example, Japan’s highest peak, Mount Fuji, is a volcano. Japan has the world's tenth largest population, with about 128 million people. The Greater Tokyo Area, which includes the capital city of Tokyo and several surrounding prefectures, is the largest metropolitan area in the world, with over 30 million residents.

Na Pali Coast



Just before setting, the moon silvers the waves washing Kalalau Beach. An old Hawaiian legend tells of Pele, goddess of fire, coming to this coast in search of a home, but she was driven away by a goddess of the sea. Their contest continues today, with the sea winning bit by bit.

Na Pali Coast



Dusk settles on Kalalau Beach at the valley's western edge. Though now a remote retreat for hikers and the occasional hermit, the largest valley on Nā Pali Coast sustained a significant population of native Hawaiians for more than 600 years. Though they abandoned Kalalau around 1919, their terraced taro fields are still evident throughout the deep valley, evoking a simpler time and a natural beauty that now attracts visitors from around the world.

The Sahel



Riding a mountain of belongings, migrants who had left Niger for Libya return home in the face of antiforeign sentiment. The Sahel was once the center of a camel-borne trade that took slaves, ivory, and gold to Europe and the Middle East, but it now lies on the margins of the world's economy. Many of the region's young men have gone to wealthier countries such as Libya and Algeria to find work.
