45. Iceland Volcano
It was in the vicinity of Reykjavik, the capital of Iceland, and soon all of Northern Europe came under the enormous cloud of ash from the volcano.
46. Belt of Venus
The Belt of Venus is a phenomenon that occurs at night dusty, when a band of pink or brown sky appears in the sky and horizon.
Cumuliform is a cloud produced by:
These cause the heating of air, usually with a lot of moisture in them. The unobstructed pyrocumulus is formed only if there is very little wind, so the spa can rise to the level of condensation without mixing too much with the ambient air.
48. Sprites, elves and blue jets
Luminous phenomena that occur in the upper atmosphere have been the poetic names of sprites (sprites), elves (elves) and blue jets (blue jets).
These strange glow were observed repeatedly by stratospheric aircraft pilots and initially were classified as UFOs. Later, the Science finally identified and gave them the name boring group of Transient Luminous Events (in English, Transient Luminous Events or TLE).
The sprites (sprites) are electrical discharges that emit a red light and produced at an approximate altitude of 80 kilometers. Their cousins, the "blue jets" (blue jets) are blue light cones are formed at a lower height than the elves, sometimes at the same time as the first. These events typically last only fractions of a second and are being studied by scientists to discover the precise reasons for its formation.
49. Amsterdam Canals frozen
The weather in Amsterdam has always been unpleasant when winter comes, and it is normal to see snow in the Dutch capital. In Amsterdam every two or three years the Amsterdam canals freeze and become a popular tourist destination.
Notably, virtually never can practice this activity in the channels running through the city, as the buildings fall cold enough power, but if you can do in the canals on the outskirts of Amsterdam, such as channel Kinderdijk
41. Moon's Valley (Argentina-San Juan)
Ischigualasto Provincial Park or Valley of the Moon, located in the far north of the province of San Juan, Department Fertile Valley is a protected area of 275,369 ha., Celebrated at the scientific level as an important reserve protects paleontological .
It is the only place you can be fully exposed and fully differential throughout the Triassic period in full and orderly. It is estimated that the geological formations of this site have an age between 180 and 230 million years. Located 330 km from the city of San Juan and 80 in San Agustin del Valle Fertil.
42. Ice Circles
Ice circles are due to exceptional conditions of the flow of rivers during freezing. If the ice on the river's surface accumulates to a greater degree in the center than at the edges, with a steady stream and very weak, it spins it creates a swirling action that produces centrifugal force finally ice a perfect circle .
43. The Cavern or Cave of the Witches (Argentina - Mendoza)
The Cave of the Witches is located in the Department of Malargue. The area comprises approximately 450 hectares and was declared a reserve in 1990. The cave entrance is located at an altitude of 1800 meters above sea level.
Cave of the Witches, is a particular subterranean environment, where once again the diversity of the planet beyond our capacity for wonder. Ancient marine rocks host a large cavity, lined with rare mineral forms stalactites, stalagmites, columns, cast, are forming a strange scenario.
Over 3000 meters of galleries have been developed through levels of calcareous rocks (limestone) from the Jurassic period. Sectors or levels typically found with abundant ammonites, molluscs dominated marine environments during the Jurassic and Cretaceous.
The Cavern is a major tourist offer in the south of Mendoza and annually hosts more than 10000 visitors. Presents beautifully decorated with different items, called speleothems.
44. Arctic Roads
The summer of 2007 will go down in history as the year Geography for the first time the sea route was opened Northwest Passage. The European Space Agency (ESA), whose satellites monitor the frozen Arctic Ocean ice has announced that the accelerated melting this region gets blown in northern Canada for the first time allowing the passage of navigation.
35. Spotted Lake
This large and curious lake, Kliluk, is among the Canadian province of British Columbia and the U.S. state of Washington. Inside are rich natural resources, but the funny thing is the strange formation of circles with white borders, where puddles reflecting mirrors or doors to other worlds sunlight with blue and green.
36. Noctilucent clouds
Noctilucent clouds, are weak in a cloud phenomena, the most brilliant and dominant in polar cloud layers. Also known as polar mesospheric clouds are in the upper layers of the atmosphere, and are visible at the end of twilight. They are composed of water ice crystals.
Noctilucent clouds form only under very specific conditions, its presence may be a clue to the changes occurring in the upper atmosphere. Since its discovery, the appearance of noctilucent clouds has been increasing in frequency, brightness and extent. It is theorized that the increase is related to climate change.
37. Faraday cage
In many cases, aircraft in flight receive "the visit" of a ray with its powerful electric shock. It is estimated that in the world, an airplane receives a ray day.
But what happens to the planes did not explode and your passengers are kept safe. Simply put, the current does not penetrate inside the device, but flows on the surface of the housing. Similarly, neither does the fuel discharge, thus avoiding misfortune
38. Ice Caves Eisriesenwelt (Austria)
These caves include the caves of the world's longest ice. At present only a small part is open to the public, small and like a maze, but enough to make the visitors feel the wonderful and mysterious quirk of nature.
39. Fire Whirls
Also known as demons of fire, appear in or around the big fire, when presented the right combination of weather conditions. The whirlwinds of fire can be generated by natural events like earthquakes and storms, which can be incredibly dangerous, in some cases, have been known to have nearly a mile high, convelocidades wind over 100 mph and a duration of 20 minutes or more.
40. Dry Iguazu Falls
Tourists in the summer of 2006 approached the border between Brazil and Argentina to see one of the most breathtaking spectacles of nature, Iguazu Falls, and witnessed the worst drought of the same
29. Sun Pillars
These spectacular pillars occur when the sun is reflected in the high clouds in the different layers of ice. It creates a column of light that reaches the sky. You can also view the moon pillars.
30. Colorful Moon
This phenomenon is something that most people have seen an orange moon hanging in the sky. This is due to scattering of light rays, while the light passes through more atmosphere (usually toward the horizon or close to it) have a much wider dispersion and we see the largest moon, and the light turns red, blue or orange (in addition to air pollutants also influence to the color).
When the moon is directly above us, or maximum height in the sky, the atmospheric layer is thinner and therefore the refraction is lower, that's when we see more small, bright and white.
31. Ball Lightning or sparks
This is a very rare phenomenon, which involves a beam into a ball and moving much slower than normal lightning. It is reported that can grow to about two feet in diameter and can cause great harm. There are reports of lightning that destroyed buildings
The phenomenon known as parhelion ("sundog" in English) is an optical phenomenon of common occurrence, associated with reflection / refraction of light, the product of a lot of ice particles in cirrus clouds. Much like the halos (in fact can and do happen at the same time), manifest as a 22 degree left or right of the sun as bright spots and even colorful in the sky.
33. Crimson Tide
Red tides are caused by the sudden influx of large amounts of color from unicellular algae that can turn whole areas of an ocean or beach blood red. Although some of these trips can be harmless, others may be precursors of deadly toxins that cause death of fish, birds and marine mammals. In some cases, even humans have been affected by red tides.
34. Moon's Valley (Brazil)
The Valley of the Moon in Brazil is a huge valley with eroded rock pools, located within a forest of Brazil, near a river. Its rock formations are considered among the oldest in the world and consist of quartz and other crystals
23. Basalt columns
Seem constructions made by human hands, but they are completely natural. The columns of mostly hexagonal basalt are igneous rocks with high iron content in the spring to the surface as magma can cool and break with surprising ways. The hexagonal basalt columns are the result of a sudden cooling of a thick lava flow, which generates deep fractures.
Although the columns formed, most of which have six sides, many of them barely have four or three sides. Contrary to what one might think, if the cooling of volcanic magma is slower, the greater the size of columns generated. One of the major basalt formations is the Giant's Causeway in northern Ireland, although we note that the phenomenon is repeated in several parts of the world
24. Ice Penitentes
The formation of snow penitents are formed at high altitude, thin leaf-shaped, pointed, looking towards the sun. Are in areas over 4000 meters, are usually visible with advancing spring, can vary from a few centimeters up to five meters. Often hamper the work of climbers and explorers who must cross to reach the top of the great peaks of the world.
The name given, "penitents", evokes the parishioners who parade covering his body with long white robes and pointy caps denoting penance during Holy Week
25. Ray Green
Also known as the green flash. This occurs very briefly before total sunset and after amanecer.Aparece as a green flash above the sun that lasts very short time, usually only a few minutes. It causadopor the refraction of light in the atmosphere
26. The Salt Desert
This immense desert of salt is in Tunupa, Bolivia and is also known by the name of Uyuni. It is the world's largest desert of salt and includes active volcanoes, tall cactus, plains of geysers that make the place a kind of infinite mirage, an otherworldly landscape.
Sinkholes or sinks are one of the most frightening of the natural world. Over time, water eroded the soil under the surface until in some cases, land yields and sinks into the ground. Many sinkholes are naturally occurring, while others are the result of human intervention
28. Voronya Cave, the deepest cave
Inside the chasm Krubeya-Voronya, located in the Republic of Abkhazia in the Caucasus Mountains and very close to the mysterious Black Sea, lies the deepest cave found by the man. With more than 2,000 meters has been and remains a dream for any caver that claims to be, and also of those who yearn to discover whether the theory to arrive "in the center of the Earth" is true.
17. Frozen Lighthouse
A lighthouse on Lake Erie, located on the border between Canada and the United States, is transformed into a giant ice sculpture because of the intense cold and the friction of the waves high winds. It is impressive to see how everything around it is frozen too.
It is very likely that the monsters and sea serpents that many terrified sailors have believed do see over time, have actually been the moving column of water belonging to waterspouts. Vortices waterspouts are usually long and thin, similar to the neck of a dragon, and motion caused by strong winds, reminiscent of a snake.
The fear and imagination of the sailors helped make fantastic supernatural properties and these unusual weather phenomena. To absorb large amounts of water ry, lakes and seas, also dragged a considerable number of small animals that are then dumped several miles away from their place of origin, thus causing the mysterious rain of frogs and fish.
19. Lightning Catatumbo
Catatumbo Lightning is a unique weather phenomenon that occurs in the south of Lake Maracaibo in Venezuela, named Catatumbo River.
This phenomenon is characterized by almost continuous lightning and silent (especially by large distances), which is produced in clouds of large vertical electrical arcing between 2 and 10 km in height (or more), as the trade winds penetrate the surface of the lake in the afternoon (when evaporation is greater) and are forced to climb the mountain system of Perijá (of 3,750 m) and Cordillera de Mérida, Venezuelan Andes branch ( of 5,000 m, approximately).
The origin of this phenomenon is in the orographic effect of these ridges that enclose and restrain the northeast winds produce a cloud of great vertical development, mainly concentrated in the Catatumbo River basin. This phenomenon is easy to see from hundreds of miles away, ie from the lake itself (where no clouds usually occur at night) so it is also known as the Lighthouse of Maracaibo, as the boats that plied the area could navigate at night without problems at the time of sailing.
It has an annual occurrence of 140 to 160 nights or more, lasting up to 10 hours per night and produces up to 280 downloads per hour. In addition, these thunderstorms produce a high percentage of all ozone generated worldwide as Catatumbo lightning can be seen as a major individual regenerative earth's ozone layer, producing approximately 1,176,000 downloads atmospheric electricity. The origin of the formation of ozone is found in the ionization of atmospheric gases with intense electric shock.
20. The Stone Forest
The Shilin Stone Forest known as "the first wonder of the world" is located 86km south of Kunming, capital of Yunnan province. Over 400 kilometers of a huge forest of stone, known for its karst topography. In 2007 fu listed as a World Heritage Site and lakes where they sink the rock formations are incredible feast for the eyes.
21. The deserts of Antarctica
Authentic Antarctic dry valleys, dark soil of gravel spread, similar to volcanic regions of the Canary Islands compared with the planet Mars. The place has a cool, dry air so that anything that dies there is preserved as a mummy or a natural freezer. In areas can be found corpses of seals may have died there for hundreds of years.
22. Socotra Island
The place looks like a space unpublished novel by Jules Verne "Journey to the Center of the Earth", the strange vegetation make it a unique ecosystem and almost alien. It is part of an archipelago of four islands in the Indian Ocean which separated from Africa about 6 or 7 million years. Like the Galapagos Islands, it contains more than 700 extremely rare species to the human eye, both flora and fauna, all, about one third are endemic
11. Mammoth clouds
Mammoth or Mammatus clouds are one of the most unusual and spectacular formations that can be found in heaven.
It consists of a set of cells that are hung from the bottom of a thundercloud. Its formation is the result of a process that could be described as convection in the opposite direction during the storm moist air flows upwards to the boundary of the troposphere, at that level the temperature drop and the air is interrupted stabilized, this causes the cloud expands horizontally rising air cooler areas without clouds.
12. Naica Caves
It is a truly unique, if you can see the pictures below you will understand what I mean, personally I think a really wonderful, many people probably want to take a short sightseeing tour of this Magnificent place, of course we must take into account that each person must have adequate protection for entry to this cave.
The cave is 300 meters deep, at a temperature of 45 º C to 48 º C and 100% humidity, so that anyone can access it, let alone spend more than 8 minutes without proper protection.
Naica Mine, where the cave is nearly 100 years, and is the primary lead producer in Mexico, but is also famous for the various crystal formations found inside, the oldest being the Cave of Swords was discovered in 1910, to 120 meters deep. The name makes sense when you see the images.
13. The hot springs in Japan Blood
Known as one of Bepu jigoku (hells of Japan) bloody hot springs comprise nine spectacular natural hot springs in the light most appropriate to be referred to the bathroom. The reddish color is due to the high iron content of hot water.
A supercell is a huge rotating storm. It may take several hours as a single entity. These storms are the most feasible to produce long-lasting tornadoes and hailstones the size of an apple.
The supercells tend to form in very unstable conditions and strong winds at high altitudes. Also show a more organized system of internal movement they have a much longer life than before. Supercell is common in the emergence of strong currents that make rotary potentially the most dangerous of the convective storm types. They can produce high winds, large hail and tornadoes length on a wide path.
15. The River Tinto
Our little Mars on Earth is in Spain, and no wonder since NASA itself has been here several experiments for its resemblance to the red planet. The area is a mining site that gives the area a barren, almost lunar appearance. The high copper content of the waters and terrain make this dye your red, hence its name.
16. Lunar Rainbow
A lunar rainbow (also known as white rainbow) is a rainbow that occurs at night. Lunar rainbows are relatively faint, due to the limited amount of light coming from the moon. Like the rainbow, lunar rainbows are always on the opposite side of the sky from which comes the moonlight.
It is difficult to distinguish colors in a rainbow moon because the light is usually too weak to excite the cone receptors of the eye colors. However, the cameras themselves are able to capture the different colors
6. Skyquake, skyquakes or Sky Earthquake
It is an explosion in the sky, the sound is generated by a particular movement of gases, which has no concrete scientific explanation yet. The phenomenon has been identified in the United States places like Florida and Pennsylvania, but also in Australia.
Many times you think might have been a plane breaking the sound barrier, but according to Meteorological pages studying strange phenomena is believed that the noise of explosion arises when a layer of air is warmer than the rest and hit the cold air comes a kind of explosion
7. Fire Rainbow
The probability of observing one of these peculiar rainbow are extremely low. Are caused by a rare convergence of rays of the sun in some clouds must have a specific position. By reflecting sunlight, the ice crystals in these clouds produce visible rays of different spectra. As it is extremely unusual to see pictures of this phenomenon is not very popular and can take a snapshot is very fortunate
8. Lenticular Clouds
Did you ever wonder about the truth of UFOs? These clouds are stationary, and are formed at high altitudes in mountainous and isolated from other clouds.
Among the climbers these clouds are seen as a harbinger of a storm. Glider pilots are continually looking clouds such as the weather system that involves a large vertical air movements, and the precise place where the updraft is very easy to predict by observing the orientation of the cloud.
The world record glider distance: 3,000 km, and altitude: 14,938 m, were obtained with this type of cloud. Airline pilots avoid them due to turbulence created in the rotor systems.
9. Fish Rain
Rare and yet real. This has occurred occasionally throughout history, from Biblical times until recent history. Meteorologists are still unsure of the cause but is believed to waterspouts (tornadoes at sea) takes over the fish of the sea at high altitude and then fall as rain.
The rain of fish is common in Honduras, occurs between May and July. Since 1998 a festival called "Festival of Fish Rain Rain '
10. Ice Wave
The SUT (also called "ice wave") is a natural phenomenon that occurs in cold climates. The phenomenon occurs when the sea creating a layer of ice that the sea itself pushes toward the coast creating a "wave of ice." Some have described it as a "tsunami" of ice. The phenomenon is rare and very strange. Some scientists believe it is a phenomenon caused by global warming
1. Aurora borealis
An aurora borealis or polar occurs when a solar mass ejection collides with the north and south poles of Earth's magnetosphere, producing a diffuse but predominantly light projected onto the terrestrial ionosphere.
Occur when charged particles (protons and electrons), are guided by the Earth's magnetic field and affect the atmosphere near the poles. When these particles collide with atoms and molecules of oxygen and nitrogen, which are the most abundant components of air, part of the energy of the collision excites these atoms to energy levels such that when you energize return that energy as visible light .
2. Light Pillars
The pillars light or bright light appear as vertical columns to the sky. These pillars are visible when light is reflected directly into ice crystals, either by sunlight (as in the two images above) or by artificial sources such as street lights or parks. Despite its appearance of solid columns of light, the visual effect is created by our point of view relative.
3. The stones that move alone
In the notorious Death Valley in the United States there is a singular phenomenon, these stones seem to float above a barren desert that was once mud. For decades, scientists have theorized plausible explanations for this anomaly, where a stone weighing several kilos can travel several hundred meters "alone."
Many believe that this movement is due to strong wind, but that does not explain that rocks of different size and weight moving at a pace parallel and in different directions. In addition, physics calculations do not support this theory, since for some stones would be needed to move higher wind speeds hundreds of miles per hour. The wind can move small stones, but how you move some tens of kilograms?
4. The eye of the Sahara
This structure Richat, on the African continent, is visible from space thanks to its nearly 50km in diameter and draws attention to its curious concentric rings. Located in the Sahara Desert, Mauritania, at a height of 400 meters above sea level. Is believed to be the product of a meteorite impact .
5. Frozen Niagara Falls
Niagara Falls often have cold winters, but not as far north as you might think by looking at photographs of the freeze of 2010. The main waterfall is on the same latitude as the city of Lugo. North America, however, lacks the influence of the warm Gulf Stream and its winters are colder than those of Western Europe, but not as much as this year, being really cold.
June 8, 2011
Until not long ago the work in archeology was filled with a large scale component.
Most of the work and findings were carried out by hundreds of hours spent digging, scraping, cleaning and decrypt sought to find areas where historical remains.
Archaeology progresses as time passes and more and more new technologies and mechanisms used to facilitate job search.
In the Great Pyramid of Giza has been working for several years a group of archaeologists provided the most advanced technological equipment.
The star machine is none other than the "Pyramid Rover", a small robot that can get to where the man can not.
Thanks to this gadget in recent years have found several doors and / or sealed chambers inside the Egyptian pyramids, but this time went a little further on their performance, as it has been able to shoot and show the hieroglyphs and marks painted on the inside, a place where the human eye had never had access.
This has been possible through a small hole that was in one of the walls and where they introduced the micro-camera.
It is not the first time that the robot has explored the hidden corridors of the pyramid, but the first in which he could focus on the details on the walls. This progress has occurred thanks to a new type of flexible micro-camera that can be bent from side to side instead of just focusing on a straight line.
With these new findings may know much more than how they were constructed over 4,500 years ago the Egyptian pyramids and the reason for the network of tunnels and secret chambers that they contain.
A few days ago the news was also known in which we explained that the use of new technological advances by American archaeologists (with the help of the BBC) and satellite imagery, had succeeded in discovering 17 pyramids under the mud and sands of Egypt.
The report revealed that 1,000 graves and about 3,000 buildings were also discovered through the application of technology in archaeological research.
