Spectacular Photos of Hurricane Earl from Outer Space

Based on the Saffir-Simpson scale of 1-5, Hurricane Earl Uncategorized 4. H Doglas astronaut Wheelock post spectacular photographs taken by Hurricane Earl from the International Space Station in his / her account at the microblogging site, Twitter.

Col. Wheelock upload pictures storm - which by the television and the media portrayed as a frightening momentum of the storm.

Meteorologists United States (U.S.) has raised the category four Hurricane Earl - warning potential 'catastrophic damage' can occur when the storm crossed the Caribbean to the U.S. mainland.

Earl has swept northern areas Virgin Island Monday morning. On Tuesday, August 31 is expected to pass through the Turks and Caicos Islands, and the Bahamas before heading to the U.S. east coast next week.

The Saffir-Simpson scale, from 1 to 5, which is used by the National Hurricane Center U.S. or U.S. National Hurricane Center - the category four Hurricane Earl is owned warning 'catastrophic damage could occur'. With a high risk of structural damage.

"It's very high risk, accidents and even death to humans, livestock, and pets due to building collapse or fall," the information the U.S. National Hurricane Center as the site loaded the Daily Telegraph, Tuesday, August 31, 2010.

Blows with the power of 215 kilometers per hour, heavy rains accompanied by Earl attack and big winds that stirred the eastern Caribbean Sea.

When moving to the northwest at 24 kilometers per hour, Hurricane Earl lowlands around the island, without making the landing.

This makes the previous warnings downgraded to a tropical storm warning for Puerto Rico, the United States and British Virgin Islands.

Earl storm strength could be stronger in the next few days. This was conveyed by monitoring the storm center.

Apparently, Extinct Dinosaurs Attacked Two Meteorite

Recent studies show that destroyed the lives of dinosaurs 65 million years ago caused by a beating at least two meteorites. Until now, scientists consider a single meteorite collision that destroyed them.

Previously, scientists have identified a large crater in the Gulf of Mexico as destructive events for the dinosaurs. Now the evidence has been found both in the Ukraine. This raises the possibility that Earth may have again bombarded by meteorites.

These new findings published in the journal Geology by Professor David Jolley of the University of Aberdeen.

When first proposed in 1980, the idea that meteorite impacts have killed the dinosaurs are still highly controversial. Then, the discovery of Chicxulub crater in the Gulf of Mexico, the United States, is considered a shot that justifies the theory.

The second discovery of the crater showed that the dinosaurs became extinct is driven by the collision of two times a meteorite, not a single attack.

Boltysh crater in the Ukraine were first reported in 2002. However, until now not clearly related to the time of the Chicxulub Crater.

In that study, scientists examined pollen and spores from plant fossils in layers of mud that fills the crater. They found, after the collision, the fern quickly meet the landscape.

Fern has a remarkable ability to bounce back after a disaster. Management layer of fern spores is considered a good indication of the impact of past events.

However, there was an unexpected discovery there. They found a second layer of ferns in one-meter layer above the first. It shows the impact of events before the collision.

Professor Simon Kelley of the Open University, another writer in the study, said, "We interpret this as the second layer after the Chicxulub impact crater."
This suggests that the Chicxulub Crater Boltysh and does not occur at the same time. They are separate layers for thousands of years seen from these two ferns. (* / BBC/OL-5)

Amazing, giant explosion in the galaxy M87

United States Space Agency (NASA) released a picture eruption 'mountain giants' in the large galaxy M87 - based on satellite observations, NASA, Chandra X-ray Observatory and the Very Large Array (VLA) of the National Science Foundation (NSF). 

The incident was observed from the amazing distance of about 50 million light years. Although different galaxies, M87 is relatively close to Earth and there is at the center of the Virgo cluster - which consists of thousands of galaxies. 

M87 cluster surrounding hot gas filled in the form of X-ray beam - detected by the Chandra satellite in blue. As this gas cools, it could fall into the center of the galaxy - and then continues to cool rapidly and form new stars. 

Meanwhile, the VLA radio observations (red) shows the M87 jet is the energetic particles produced by black holes (black hole) that interrupts this process. 

This beam is relatively cold gas lift near the galactic center and produce a shock wave in the atmosphere of the galaxy - because his strength is supersonic. 

Interaction of 'explosion' in the cosmic galaxy environment is very similar to the eruption in Iceland Eyjafjallajökull this happened in 2010. 

In Eyjafjallajökull, pockets of hot gas that exploded on the surface of lava produces shock waves that can be seen through the gray smoke of the volcano. 

This hot gas then rises into the atmosphere, which also dragged the dark ash. 

This process can be seen in movies about volcanoes Eyjafjallajökull where the smoke propagating shock wave, followed by the emergence of dark clouds of ash into the atmosphere. These clouds disrupt European aviation. 

In Eyjafjallajökull analogy, these particles of energy generated around the emergence of a black hole through the X-ray emitting cluster atmospheres - raised the most cold gas near the center of M87. 

This is similar to volcanic gases heat up the dark cloud containing particles of ash. And like a volcano on Earth, a shock wave can be seen as a black hole (black hole) pump energy particles into the cluster gas.

Objects thrown in Cirebon Meteor New Type?

 Cirebon-Indonesian citizens, Wednesday night, August 18, 2010, was startled by an object dropped from the sky misterus. National Aeronautics and Space Institute has not verify it as a meteorite. This is because the material is different from the usual meteorites. 

Objects found in the form of a melt and burn when he fell. This happens only once. 
"Items found at the scene of the melt and burn when it fell. Only once this happens like that," the researchers said Lapan, Thomas Djamaludin. 

National Aeronautics and Space Institute also received information from the surrounding community who watched, it glided back to Earth with such light is burning out. Light, said Knopf, seen by the people who are quite distant locations. 
"From the testimony of the community, when slid down, it can be seen from the people who were three miles from the scene," he said. 

According to Knopf, has been found in meteorites that fell to earth does not exist in the form of a melt, usually in the form of solid or ice. 
"If the meteorite, which is common for this is in the form of iron, rock, a mixture of iron and rock, and the most rare is the ice," he said. "The meteorite in the form of ice is very rare because it melts before reaching the earth." 

Thus, he said, Lapan can not conclude whether the objects that fall in Cirebon was indeed a meteor. Lapan, said Knopf, still need time to examine the elements contained therein. "It should be further analyzed to determine its chemical composition and object is what from where," he said. 
On location, objects falling from the sky was a hole about one meter in diameter and cause a stinging smell of sulfur. It was melting so menghujam ground, and thunderous noise.

This month, Three Planets emerging

August was a good time for astronomical observers, especially those who love observing celestial bodies around the Earth. Because, in this month a lot of scenery space that can be enjoyed and studied.

In the next few days, three of the brightest planets in the Milky Way can be seen directly from Earth. Planet Venus, Mars, and Saturn can be seen as they approached each other.

As quoted from Space.com page, on the night of 7 and 8 August when the U.S., these three planets will be only five degrees apart from each other and can be witnessed in the western sky after sunset.
The best scenery of the three planets can only be seen 60 to 90 minutes after sunset before they will be increasingly drowned and no longer in the top horizon.

Together they will form a triangle formation. For amateur observers, the following trick to identify each planet. Venus is the largest and brightest planet than Mars and Saturn. The planet Saturn will be located right next to Venus, with a yellowish color. Then, Planet Mars will be above the planet, emitting a reddish color.

Moon will participate enliven the scenery of this universe on August 12 evening until late August 13. At that time, in the form of crescent Moon will be on the left side of Venus with Mars and Saturn above them on the underside. And do not forget that Mercury will be living under the earlier set of celestial bodies. All will gather in the western horizon.

Two of the first week in August to be a good time to see Mercury, the planet is relatively unexplored. On August 12, the Moon looks much thinner, will be on top of Mercury.

Finally, on August 27, Moon in the form of nearly full moon will be located below Jupiter, king of the planet. At that time, look into the eastern sky begins at 9 tonight.

The Secret Behind Jupiter's Giant Size

Jupiter is the largest planet in the solar system. 120 times the size of Earth. However, recent measurements by the spacecraft reveal the planet's core at most 10 times the size of the planet we inhabit.

Recent studies found that about Jupiter, the giant planet has a core of very small compared with the size. Scientists believe, so the planet Jupiter, the largest in the Milky Way Galaxy because he swallowed the other small planets, before the swell.

As disclosed in the site of science, New Scientist, the core of Jupiter thought to have greater evaporation in a collision with a planet the size 10 times the size of Earth. This study provides new insight into a process that is fierce in the early formation of our solar system.

Researchers from Peking University, China has to imitate what might happen in the event that the collision. The simulation results show, rocky planets closer to Jupiter will be demolished as it hit the giant planet's atmosphere.
Half an hour later, the planet would fall into the core of Jupiter. Heavy elements in the core as the metal will evaporate and then mixed with hydrogen and helium in the atmosphere of Jupiter.Scientists believe this may explain why the core of Jupiter is very small but extremely dense atmosphere.

Douglas Lin of the University of California, said that while the smaller planet does not bump into him, Jupiter will continue to grow into a giant planet itself.

The research team said, elements in the planet Saturn may also be caused by something similar, a collision with a smaller planet.

The planets in our solar system created by collisions between dwarf planets that orbit the Sun, who was also born. In the process the impact, small planets to melt and form planets is greater.
Earth and Moon are the result of a collision between two giant planets about the size of Mars and Venus.

Collision process occurs in less than 24 hours, and the temperature of the earth at that time was very high, around 7000 degrees Celsius, where rock and metal can be melted.

Mars Approach to Earth August 27, Really ?


Lately, the news circulating on the internet that Mars will be closer to Earth on August 27th. It is said that visits to the direct eye, the red planet will look at the full moon from Earth.
At that time, Earth seemed to have two months.

The message that this is not the first time in circulation. The same message has been outstanding in 2004 and then - in the email format - titled 'Mars Spectacular' which is sent by an anonymous source. However, no mention in what year, the momentum of August 27th it will happen.

This news spread rapidly through cyberspace. Fill in the email, on August 27th Mars will be closer to Earth, only within a range of 34.65 miles (55 million kilometers), rare events that happened in the last 60,000 years.

Besides the appearance of Mars for the appearance of the Moon, the planet approaches the Earth's gravity will cause problems on Earth, creating problems that interfere with the tide.

Fortunately the approach of Mars to Earth news is false news. According to a spokesman for Scienceworks Planetarium, Rohan Astley, email continues to circulate the same every year, approaching the Month in August.

He added, did Mars ever closer to Earth, but not this year.

"Mars is ever closer to Earth in August 2003, but the appearance of the red planet was only clearly visible through a telescope, not with the direct eye," the page is loaded News.com.au, Monday, August 9, 2010.

As the page loaded Space, August 27th is meant by the email, is August 27, 2003, when Mars closer to Earth within 55.7 million kilometers.
Hubble telescope when it was perpetuating the image of the Mars spectacular. But then, with the seen direct eye, Mars looked no more than just the bright orange star, did not look like a full moon.

This year 2010, Mars will appear small, not like the appearance in 2003.

The appearance of 'Bull's Eyes' on Mars

Images 'bull eyes' post was taken by the HiRISE camera on the orbiting satellite
An appearance of 'bull's eye' on Mars sent to Earth from the camera's high-tech U.S. space agency, NASA's orbiting the red planet.
Photos unusual crater was taken by a camera High Resolution Imaging Science Experiment (HiRISE) is mounted on the Mars Reconnaissance Orbiter satellite.

NASA released this photo recently. Although the actual photographing Mars Reconnaissance Orbiter's unique crater on July 9, 2010 last. Its location at 46.6 degrees latitude and 194.9 degrees east longitude on the surface of Mars.

Now the task of scientists to uncover what exactly is causing the bulge in the center of the crater on Mars.

Whether it is a product of the layer below the surface of Mars or created due to the impact of collision.
"Collision on Mars could result from the material layer is strong or weak, for instance rich with no non-ice-ice-rich, resulting in a terracing, as seen between the holes inside and outside," wrote Sarah Milkovich, HiRISE science team member at the University of Arizona, like a loaded Space.

Previously, scientists have examined the terraced craters to estimate the thickness of lava flows on the Moon and in several other places.

"Sublimation is equitable and periglacial erosion of ice-rich material is open on the inside of the crater may explain why relatively few bumps it off, not right in the middle, from the terrace and the edge of a larger crater," writes Milkovich.
Bulge in the middle of the crater 'bull eyes' can also be explained by the theory that it was the impact of collision.
Previously, HiRISE reveals the appearance of the face of Mars taken by Viking 1 satellite owned by the United States on July 25, 1976. The appearance sparked thousands of conspiracy theories.

HiRISE shows a human face on Mars is a large rock in the middle of the desert.
HiRISE images are images generated from the nearest object was phenomenal. HiRISE images taken from the Reconnaissance satellite orbiting 300 miles above Mars - much closer than the position in 1976, 1873 miles.

Solar storm effects for Earth

The threat of 'tsunami sun' who had preached against the earth crowded nil. There was no tsunami or storm the sun on Tuesday, August 3, 2010.

Research Professor of Astronomy National Aeronautics and Space Agency (Lapan), Thomas Djamaluddin, say, a tsunami if the sun, will not adversely affect the earth. Tsunami affects only the sun around the point of explosion.

That allow an impact on the earth is the solar storm. IBHS if the burst of large-scale solar masses and towards the earth.

Research based National Oceanic and Atmospheric Administration (NOAA), sponsored by the United States space agency, NASA, solar storms occur when it comes up flares or large explosions in the atmosphere of the sun with its super high.

Solar storms can cause power stepping up to billions of watts of electricity. When it comes to the earth, its emission will affect the earth's magnetic field which in turn have an impact on satellite systems, electricity, and radio frequency. Earth at risk of losing electrical power.

Is the usual cycle of solar storms that occur every 11 years. However, this cycle is expected to reach its peak in 2012-2013.

Based on these predictions, a number of space agency has tried to prepare a number of strategies to cope with the storm the sun. Strategies to anticipate the loss of electric power, satellite, and radio frequency that sustains the life of today's modern society.

Solar storm ever hit the earth on 1 September 1859. However, at that time did not really impact because life in those days, electricity has not been sustained.

The threat of potential solar storm that struck the earth in 2012 is the time to reinforce the myth about the end of the world or the end of 2010. A myth is not enough scientific evidence to be trusted.

Martian life, Find The proof is in Nili Fossae

Nili Fossae formation on Mars have preliminary evidence that save life on Earth.
Search other life in outer space now leads to two places. First, Titan. Satellite of Saturn that has a lake of methane and ethane, and Enceladus, the water vapors - conditions like a place you can live a life.
The seond focus point to Mars, which is closest to Earth. Therefore, the red planet has a deposit of sulphate. On Earth, sulfate is the storage location of ancient organisms.

 
It is probable, sulphates on Mars also keeps a track record of life, just as on Earth.
As the site loaded the Christian Science Monitor (CSM), on Mars there are locations that are rich in minerals known as Nili Fossae.
This allegedly is the main location of the search traces of ancient life on Mars that may exist about four million billion years ago.

 
In his study, scientists using NASA satellite instruments, Mars Reconnaissance Orbiter to study the clay carbonate rocks on the surface of Mars. Layer was allegedly an ancient Martian era relic that is also called Noachian Period.

 
The scientists did not conclude that the Nili Fossae is actual proof of the existence of living beings on Mars. Only becomes possible.
"We think, of hydrothermal activity in Nili Fossae provide energy for biological activity on Mars in the early days," said the creature seekers scientists ekstraterresterial Search for Extraterrestrial Intelligence Institute (SETI), Adrian Brown.

 
These findings will be described in the journal Earth and Planetary Science Letters.
Brown and colleagues studied the hydrothermal formation of clay-carbonate rocks in the Nili Fossae region on Mars.

 
Their results indicate there are similarities between the formation of carbonate rocks in the Nili Fosae with traces of early life on Earth, and biological, particularly in Western Australia.
Nili Fossae region similar to the condition of East Pilbara in Western Australia - which stores the evidence of early life on Earth.
"In this article, we discuss the potential of Archean volcanic in the East Pilbara region of Western Australia as an analogue for the Noachian Nili fossae on Mars," said Brown.
"They indicate the existence of biomarkers - or proof of the existence of living organisms."
Nili Fossae is one of seven candidates for unmanned landing sites of NASA, Mars Science Laboratory, in the following missions.
