First detailed images of ocean currents


The European satellite GOCE-Explorer Gravity field and Ocean Circulation, for its contraction in English, was able to obtain, for the first time, extremely detailed images of how water currents move around the planet. These images record the effect of gravity on the ocean currents, which allows scientists to determine the direction and speed of the same.

The data obtained by Goce used to improve climate models studying how the oceans move heat around the globe. In the new map you can clearly see the famous Gulf Stream, the most intense of all streams, in which the water passes rapidly, reaching even more than a meter per second, in some places.

An asteroid with us on our trip around the sun


Astronomers detected an asteroid which follows the orbit of the Earth around the sun. The rock-between 200 and 300 meters in diameter and 2010 TK7-christened it the Trojans, which are those that share an orbit with a planet near stable points. Because they remain in front of or behind the planets in the same orbit, never collide with them.

According to the science specialist for the BBC, Jonathan Amos, it is a fascinating finding because the relative stability and proximity of the Trojan asteroids makes them potential targets for future space missions, when they go beyond the International Space Station (EEI).

The telescopes of the world is ready for a giant asteroid


Has a diameter of more than four football fields or, as defined by NASA, is as big an aircraft carrier. This is a big one, in terms of space; pass close to Earth. YU55, as the space rock is called circular, not dangerous in any way, there is no risk of collision with the Earth as it is in the closest point (about 324,600 kilometers), its gravitational effect on the Earth will be so minuscule that can hardly be measured. But his interest in another aspect: its rarity.

NASA astronomers discovered the smallest planet


Astronomers discovered the smallest planet outside our solar system. This is the first that is certainly rocky like Earth. Measurements of extraordinary precision-called Kepler showed that 10b is 1.4 times the diameter of Earth and a mass 4.6 times greater than he. However, because it orbits very close to its star, the exoplanet could not support life. The discovery has been hailed as "one of the deepest in the history of mankind."

Why some planets orbit backwards?


Experts from Northwestern University in Illinois, USA, conduct a study that was published in the scientific journal Nature, and which required to find the reasons for this phenomenon that breaks with the standard theory of planet configuration. According to this theory, a planet must rotate in the same direction as their star, just like in our solar system. "It's very strange, and it is even rarer because the planet is very close to the star," said Frederic Rasio, an astrophysicist at Northwestern University.

Earth in the third dimension


The German satellite TanDEM-X was launch into orbit on a mission to map more accurate to be made available to the surface of the Earth. The satellite will fly radar technology with identical platform called TerraSAR-X launched in 2007. Both measured variations in the height of the globe with an accuracy of better than two meters.

Its digital elevation model will have many uses, from helping military jets fly ultra low height to show where rescue workers was worse the damage caused by an earthquake.

Significance makes Earth look like a potato


A satellite is record variations in Earth's significance gives us a different view of our planet from space looks like a potato. And yet, the information provided by this model is the sharpest view we have of how gravity varies across the Earth. The device was released by the team working on the European satellite GOCE.

Are a new type of planets and dark alone?


U.S. astronomers discovered what they explain as a new class of planets: 10 dark bodies floating lonely far from any host star. The discovery was detected in the center of the Milky Way. The scientists, who published the findings in the journal Nature, believe these planets, which are the size of Jupiter, were expelled from their original planetary systems.

According to Professor David Bennett, professor of astrophysics and cosmology at the University of Notre Dame in Indiana,

Mars is still an "embryo" of planet


The planet Mars twisted in record time and reached its current size in just three million years, much faster than scientists thought. That rate of formation of the Red Planet could explain that its mass is one tenth of that of the Earth. The study supports a theory more than two decades, according to which the planet remained small because it avoided collisions with what would become the "planetary construction materials", ie other objects in space. The finding is published in the journal Nature.

In the early days of the solar system before the planets were formed, a cloud of gas and dust surrounding the Sun Scientists believe that the planets arose from the accumulation of this material driven by electrostatic energy.

The mysterious birthday Neptune


Neptune is approximately 4400 million kilometers away from Earth. Neptune is about to celebrate its first birthday. On July 12 will be a year-Neptunian-terrestrial or 164.79 years since its discovery on September 24, 1846. But why do we know so little about the distant planet?

At approximately 4400 million kilometers from Earth lies Neptune, the first planet in the solar system to be discovered deliberately. After classification of the planet Uranus in 1780, astronomers have been puzzled by his strange orbit. Scientists concluded that either Isaac Newton's laws had a fundamental flaw or something else-another-planet Uranus was pulling its expected orbit. And so began the search for the eighth planet.

Hubble finds out fourth moon of Pluto


 The Hubble Space Telescope exposed a fourth moon orbiting the planet Pluto, as NASA said.


The Hubble was looking rings around the planet, located in the outer edge of our solar system, when he came across P4, the temporary name has received newfound moon.

Mercury shows best kept secrets


Mercury place in foreign hidden craters, volcanic nature has an powerful, large amount of sulfur and convulses with energy blasts. These are the first findings of the data obtained by NASA's Messenger probe.

After nearly three months orbiting Mercury, this device has sent to Earth new data-with some surprises, on the composition of the Solar System planet closest to the Sun. The probe entered orbit around Mercury on March 18 and thus became the first spacecraft to achieve.

Discovery of a diamond planet


A new planet, made of a material alike to diamond ultradense, was discovered by a group of Australian scientists. It could be the most valuable rock sighted but never too far from the reach of explorer’s golddigger. At about 400,000 light years from Earth, the planet is located about one-eighth of the distance that separates us from the center of the Milky Way. Believed to be the only remnant of what was once a giant star in our own Milky Way.

That star, is now a pulsar, a type of neutron star characterized by very intense emit radiation, which was discovered in 2009. Its diameter is only 20 kilometers. Australian scientists found that the radiation was interrupted every two hours and 10 minutes, a sign that another celestial body orbiting around it. After observation with large telescopes in the UK and Hawaii (USA), discover the new planet.

Brightness
The planet appears to be smaller than Jupiter but has more mass. The scientists, who published their discovery in the journal Science, believe it is the densest planet ever discovered and composed mainly of carbon. Because it is so dense, scientists believe that carbon must be crystalline, so a large part of this exotic diamond planet would.

His theory is that high environmental pressure caused his core crystallized carbon into diamond. What is not clear is how she should look closely watched. Ben Stappers of the University of Manchester told Reuters that can only speculate: "I imagine that there would be a picture of a very shiny object."

Discovered a planet 36 light years away could harbor life


A planet with features that make it suitable for harboring life was discovered by a group of astronomers who used a powerful telescope in Chile. He has been called HD85512b and is about 36 light-years away. Its discovery by European astronomers announced a Monday and the scientific community considers it as already known planet other than Earth most likely to contain life.

The theft of a million dollars in the Large Millimeter Telescope in Mexico


Sometimes the study and observation of the universe is very Earthlings encounter problems, as with the Large Millimeter Telescope located on top of an extinct volcano at 4580 meters altitude in Puebla, east of Mexico. Recently the Attorney (prosecutor) General's Office (PGR) arrested two youths who are accused of stealing between 126 and 128 subpanels aluminum and nickel that would be installed on the device.

A billion pixels for a billion stars


E2v has worked for more than five years to produce all of the Gaia CCD. I doubt those going to buy a can of paint to store hardware chain Homebase has in the English town of Chelmsford think too much about what happens in the factory adjoining art. It is the headquarters of e2v; a company that gained fame after World War II manufactured lamps for television industry but now produces camera sensors for some of the most important space missions.

The key to the origin of the universe could be under water


The telescopes are composed of a series of strings coupled to glass beads. Soon humanity will have many more "eyes" scanning the universe in search of particles that we can solve the existing enigmas surrounding its origin. The high-energy cosmic neutrinos can be detected only by a few hidden devices in the most unexpected places: Inside Mountains, underground, underwater, and even in solid ice.

Scientists use them to unlock the mysteries of the universe, to know the nature of dark matter, the evolution of stars and the origin of cosmic rays.

Chilean telescope exposes the largest group of galaxies


An international team of astronomers discovered the group of young galaxies in the Universe largest telescope thanks to VTL (Very Large Telescope, Very Large Telescope), the European Southern Observatory (ESO, for its acronym in English), located in the Chilean desert Atacama.

Technically, scientists called their discovery ACT-CL J0102-4915, but I know so familiar with the name El Gordo, Spanish for having discovered in Chile and in honor of his size. More than 7,000 million light years from Earth, this galaxy cluster is the largest ever seen in the distant universe? It was discovered early.

One possible explanation for UFOs (finally)


Some unidentified phenomena like UFOs, could be explained by a light or electrical phenomenon little known, says Australian astrophysicist Stephen Hughes.The scientist made a detailed study of an unusual event occurred in 2006 when a large number of meteors were seen in the sky over Brisbane. His appearance came while a bright green object was seen rolling down the nearby mountains.

Looking for life in a piece of heaven


A exclusive meteorite that could hold clues to the birth of our solar system may now be considered as reached London, the Natural History Museum (NHM). The Ivuna meteorite, which until now was part of a private collection of an American, has the same chemical makeup than the solar system formed about 4,500 million years.

Ivuna landed in Tanzania in 1938 and was a rock of 750 grams which was then divided into several samples.

Life in the deep sea


The seabed of our planet is teeming with life forms unknown, according to an article in the journal Nature. Bacteria on the seabed could be older than life on the planet's surface.
Scientists suggest that between 60% and 70% of all bacteria live deep in the seabed of the Earth, away from sunlight. Some of the new bacteria identified are about 16 million years and survived some 400 meters deep.

Europe creationism discussion


Creationism rejects the evolution of species through natural selection. The Council of Europe, which is responsible for ensuring respect for human rights in the Old Continent, began to discuss a report that warns of the dangers of teaching creationist theories in schools.

Creationism challenges the commonly accepted theory of evolution of species and holds that the earth is no more than 10,000 years old and

Prepare for the encounter with extraterrestrials


World governments should start preparing a synchronized way to an ultimate meeting with extraterrestrial life, says an impressive group of scientists in the UK. In an edition of the journal Philosophical Transactions A of the Royal Society British institution, the scientists note that for the first time in the history of mankind "is a realistic possibility of whether or not we are alone in the Universe."

The "broth of life" could cook with element alien

The examination of meteorites realizes too much numbers of left-handed amino acids. There is more evidence than ever that life on Earth may have originated as a result of material from asteroids or comets. Previous research had already shown as amino acids, the structure blocks for constructing natural life could form anywhere in the universe.

These molecules can form in two different versions, but life on Earth is based on only one of them. Now research published in the Astrophysical Journal Letters shows how conditions that 

Does the meteorite that brought the instructions for life on Earth?


Some think that meteorites brought indispensable materials for the beginning of life. A meteorite discovered in Antarctica would give strength to the argument that life on Earth may have started due to a boost from space, scientists say. The analysis shows that the meteorite is rich in the gas ammonia. Contain the element nitrogen, found in proteins and DNA that form the basis of the life as we know.

The diamonds and the Origin of Life


Small pieces of diamond fake an embryonic Earth may contain the oldest traces of life, according to a study. The analysis showed that the crystals contain a type of carbon often associated with plants and bacteria. The rare gems were found inside zircon crystals, formed a few hundred million years after the Earth formed. In an article published in the journal Nature the researchers caution that the results are not definitive proof of early life forms, but "do not exclude" the possibility.

Scientists observe "evidence" of extraterrestrial life


A traffic journal asked thousands of researchers to observe the claim of a NASA scientist that found evidence of fossilized bacteria on three meteorites aliens.

Richard Hoover, an astrobiologist at Marshall Space Flight Center of the U.S. space agency said that the bacteria found are fossilized remains of organisms that lived in the heavenly bodies, comets, moons and other-that gave rise to the three meteors.

UFOs: the truth is out there


Let me be completely honest. I do not believe in UFOs. Nothing could persuade me to believe that there are aliens flying over us or to come to tea. It is one of the few issues on which my opinion is taken and no evidence that they can cite you changes it. I always thought that there is no evidence that comes from the Martians but was planted by earthlings to convince us that aliens exist. But I'm interested in the stories of close encounters of the third kind? 

Concerned about UFOs


The subject of UFOs has long captured the popular imagination but also the attention of governments around the world, showing secret documents made ​​public Thursday by the National Archives of the United Kingdom. Documents Ministry of Defense, which will be in the public domain for a month, show how the UFO phenomenon was discussed seriously in high-level talks between government and security services worldwide, including the United Nations and the Agency Central U.S. Intelligence, CIA.

"New evidence" of aliens in New Mexico

Communication released by the Federal Bureau of Investigation (FBI, for its acronym in English) has generated enthusiasm among urologists who see evidence of the existence of aliens with humanoid form. Some even claim that the files appear to provide evidence for the theory that aliens landed in Roswell, New Mexico, in 1947.The documents in question date back to 1949 and tell how three men, on patrols several kilometers away from each other, said they had seen an unidentified flying object (UFO)

Hubble captures a stunning image of the brightest galaxy


The Hubble Space Telescope has captured an image of a spiral galaxy with bars that can help understand the Milky Way.
Most of the known spiral galaxies fall into this category of "slash" - which is defined by its pronounced structure bars across their centers.
The existence of this structure can indicate the age of the galaxy.
Two thirds of the nearest galaxies are young and bar, while only a fifth of the oldest and most distant have it.
The new image is a milestone in the long history of the Hubble Space Telescope in the stunning astronomical imaging.

The orbits of the planets


Why all planets occupy the same orbital plane around? The best guess is that all astronomical move in the same orbital plane because they were born of one and the same flat disk of matter.

Theories suggest that the solar system was originally a huge mass of rotating gas and dust, which was perhaps initially spherical. At some point in this process of condensation and becoming more pronounced rotation,
