Among the electrical phenomena that occur in the Earth's atmosphere, the Fire of San Telmo is one of the most difficult to see. The Fires of San Telmo, in reality, are not any kind of fire. It is a kind of plasma that is caused by static electricity in the atmosphere. It could be said that it is a discharge of light similar to the sparks produced by metallic or pointed objects during a great storm.

An aurora is a luminosity that occurs at high altitude, and generally above 60 ° latitude, although it is also observed in other areas. As it occurs in the northern or southern hemisphere, it is called aurora borealis or southern aurora. The term polar aurora applies in both cases. The aurora consists of rapidly changing spots and luminous columns, of various shades.
This photo was taken by the Shuttle team when it was over Sudan, near the Red Sea. Sahara is a great desert of North Africa that constitutes the western sector of the great band of arid lands that extend between the Atlantic Ocean, to the west, and the Red Sea, to the east.
The surface of the Earth is broken. The cracks in the earth's crust, known as faults, can travel hundreds of kilometers. These failures are often the locations in which the main earthquakes occur, due to the drift experienced by the tectonic plates that cover the Earth's surface.
The cracks or crevices in the Moon, first discovered over 200 years ago with a small telescope, appear throughout the Moon. For now three types of rhymes are known: sinuous, with many meandering, arched curves that form wide arches, and straight, like the Ariadaeus rhyme shown in this photo.
A volcano is a geological formation that consists of a fissure in the crust of a planet on which a cone of volcanic matter accumulates. On top of the cone there is a concave chimney called crater. The cone is formed by the deposition of molten and solid matter that flows or is expelled through the chimney from inside the planet.
The spectacular Iguazu Falls are located on the border between Argentina and Brazil. The Iguazu River, through a large horseshoe-shaped arch 4 km long and about 70 m high, rushes into the Devil's Throat, a canyon that then continues for 20 km to the mouth of the Paraná.
The Colorado Plateau, located in the state of Arizona, is home to some of the most impressive wonders of nature. The Monument Valley are located within that region. It is an impressive effect of erosion that has made the softer materials desert, and is modeling rock structures based on wind and dust.
The high waves that approach the flat beaches begin to break at a considerable distance from the coast creating a foam that gradually spreads over the descending surface of the wave. The beaches are formed by sediments of different sizes, which can range from fine sand particles to boulders.
The aurora is the brightness caused in the Earth's ionosphere by the interaction of its magnetic field with charged particles from the solar wind. They are observed near the polar regions, and are known as Aurora Austral (southern hemisphere) or Boreal (northern). The brightness of the aurora occurs when the solar wind collides with the particles of the upper layers of the Earth's atmosphere, and is sometimes reinforced by high-energy subatomic particles from sunspots.
The first and only total lunar eclipse of 2001 occurred on January 9/10 when the Moon slid through the earth's shadow. Unlike a total solar eclipse, a total lunar eclipse is visible to anyone on the night side of the planet during this event. The night for this celestial event included Europe, Asia and Africa, where the Moon could be seen immersed in the gloom or dark part of the Earth for 62 minutes and passed exactly north of the center of the shadow.

If it is beautiful to see a large canyon on the earth's surface, it is most spectacular to see it underground. This is the case of Skocjan Grottoes, which are located in the Kras region, in southwest Slovenia. For thousands of years the Reka River has been eroding this natural space underground, to form a large underground canyon.
Each of the four parts into which a Solar year is divided is known as a ground station: spring, summer, autumn and winter. Solar year is understood as the time it takes for the Earth to revolve around the Sun, a path called translational movement. The axis on which the Earth rotates is inclined.
Photos of the Earth and the Moon 160 Photographs of the Earth and the Moon explained. In this collection of images of the Earth and the Moon, taken from various sources and grouped here for their educational and cultural interest, we intend to show a series of images about our planet and its satellite that are attractive and interesting.
On Earth, rocks are eroded by wind and water, creating solid soil and sand. On the moon, the long history of micrometeorite bombardment has practically pulverized the rocky surface creating a layer of lunar soil dust or regoliths. This lunar regolith could be a good scientific and industrial material.
Sometimes, large regions of the Earth catch fire. Since fire consumes oxygen and because oxygen is an indicator of life, fire on any planet could be an indicator of life, but in ours, it is usually a destructive indicator. Most of the Earth's soil has been burned by fire at some point.
The Sahara desert ranks first among the hot deserts of the world. Globally it is the third largest desert, after Antarctica and the Arctic. Its extension covers a large part of North Africa, similar to the size of the United States. As for figures, the Sahara has 20 liters of water per square meter, and "enjoys" temperatures that can reach 60 degrees Celsius in the shade.
On the banks of the world, under 19 meters of ice and gravel, there is a lake that can contain an ecosystem completely isolated from surface life. In a modern version of the classic of the universal literature, Lost World, by Sir Arthur Conan Doyle, NASA finances a group of scientists who are planning a mission to drill on the surface that covers the lake and obtain a water sample for Your analysis
Earth is a planet-ocean. From the Earth's low orbit, the Sea Star spacecraft instrument reviews the colors of all oceans to see changes in the climate and biosphere of our aquatic world. The images of the SeaWiFS can also follow the color changes in the land masses, as in this photograph of the Planet, taken on January 27, 2000, which shows us the region of the great lakes and the area of the Atlantic coast in North America.
With the name of El Niño, a climatic phenomenon is known to occur cyclically. In periods that occur every three to seven years, the surface waters of a large part of the tropical Pacific Ocean are heated or cooled between 1 and 3 degrees Celsius. It seems a ridiculous figure, but this change in temperature wreaks havoc worldwide.
