how to handle an emergency, like a huge asteroid that is heading towards Earth!

CAPE CANAVERAL, Administrator of NASA, Charles Bolden, has a recommendation on how to handle an emergency, like a huge asteroid that is heading towards the city of New York: Pray. Good advice, if the USA believed in God; but that is not the current case, is it?

That is all that the United States-or any other country could do right now about unknown asteroids and meteorites that could travel on a collision course with Earth, Bolden said Tuesday lawmakers at a hearing before the Committee on Science of the House of Representatives.

An asteroid estimated to have been 17 meters in diameter exploded on February 15 Chelyabinsk, Russia, generating shock waves that smashed windows and damaged buildings. More than 1,500 people were injured.

Later that day, an asteroid larger and unrelated, which had been discovered the previous year, passed within 27,681 miles of Earth, closer than television satellites and climate orbiting the planet.

The events “serve as evidence that we live in an active solar system with potentially dangerous objects that pass through our neighborhood with surprising frequency,” said Rep. Eddie Bernice Johnson, D-Texas.

“We were lucky that last month’s events were just an interesting coincidence rather than a catastrophe,” said the committee chairman, Lamar Smith, a Texas Republican, who convened the hearing to find out what is being done and how much money is needed to better protect the planet.

NASA has found and is tracking about 95 percent of the largest objects flying near Earth, those with a diameter of 1 km or more.

“An asteroid that size, a mile or more, it could plausibly end civilization,” said science adviser John Holdren White House lawmakers at the hearing.

But about 10 percent of an estimated total of 10 000 possible asteroid “kill cities”, those with a diameter of 50 meters, have been found, said Holdren.

The average size objects that fall on the Earth every thousand years.

“From the information we have, we do not know of an asteroid that will threaten the U.S. population,” said Bolden. “But if that happens in the next three weeks, pray,” he added.

Besides increasing its monitoring efforts and international arms companies, NASA is seeking to develop technologies that divert an object that could travel with collision course with Earth.

“The chances of a near-Earth object hit us causing a huge number of casualties and destruction of infrastructure are very small, but the potential consequences of such an event are so great that it makes sense to take the risk seriously,” said Holdren.

Makes about 66 million years ago, an object 10 kilometers in diameter would have fallen into what is now known as the Yucatan Peninsula in Mexico, leading to the extinction of the dinosaurs, as well as most of the plant and animal life on Earth.

The asteroid that exploded over Russia last month is the biggest thing that has beaten the atmosphere of the Earth from the Tunguska event of 1908, when an asteroid or comet exploded over Siberia, felling 80 million trees over 2000 150 square kilometers.

Asteroid nears Earth

The U.S. space agency NASA released the first images of the asteroid is expected to pass tomorrow to just 27, 860 kilometers from Earth, the closest approximation of a cosmic object registered hazardous to our planet.

On its Web site, NASA posted a animated sequence in black and white made up of three images that you can see the path of the asteroid when it is still 748,000 miles from Earth.

The sequence was created by astronomers Remanzacco Observatory in Italy, from photos taken by remote control by the Faulkes Telescope South at Siding Springs (Australia), according to the space agency.

The asteroid was detected by amateur astronomers affiliated Sagra Observatory (Mallorca, Spain) a year ago, when it was at 4.3 million kilometers from Earth, and the planet is approaching 28,100 kilometers per hour.

The space rock, the size of half a football field, is so opaque that astronomers can only observe its trajectory in the infrared range of the spectrum which reflects the sun’s heat

Solar flare will hit Earth on Saturday (9:00 to 13:00 GMT)

According to NASA, if the eruption is strong enough, could damage communication systems and power grids

DALLAS, – A solar storm will arrive at Earth on Saturday causing geomagnetic conditions that could cause disruptions in satellite and radio signals, reported the National Aeronautics and Space Administration (NASA).

A huge flare and eruption of solar plasma from the Sun reported, called coronal mass ejection, or CME, which is now going directly toward Earth at about five million miles per hour.

It is expected that the effects of radiation or solar flare to reach the Earth between 5:00 and 9:00 am Eastern Time U.S. (9:00 to 13:00 GMT) on Saturday, according to forecasts by the NASA researchers and the Climate Prediction Center NOAA‘s Space.

The solar flare on Thursday was officially classified as an X1.4 class flare, so it becomes the strongest in the summer so far.

The flare and CME emerged from a massive sunspot known as AR1520, which scientists say could be up to 300 thousand kilometers long.

The arrival of the radiation by the coronal mass ejection to Earth likely to generate moderate geomagnetic storms that will last until Sunday, with the potential to cause temporary interruptions in radio and satellite networks as well as energy.

transit of Venus between the Sun and Earth

The transits of Venus, visible in Central America and North America and will continue to Europe, is a unique opportunity for science but also to human curiosity, say experts.

“Essentially it’s an eclipse, the interesting thing that happens every hundred years,” said Eduardo Araujo, a scientist at the National Oceanic and Atmospheric Administration (NOAA).

“The planet passes between Earth and Sun and looks like a small point that the Sun travels,” he said.

The distance is so great that it has no effect on the earth but it is a “great opportunity” for scientists to study the wavy motion, gravitational forces, density, and many aspects as possible.

Now begins the collection of data, the results will not be immediately, studies will be completed in months and present the first findings.

“It’s an opportunity from the standpoint of the scientific world and from the point of view of human curiosity is unique too,” said Araujo, who recalled that not all generations have the opportunity to see a transition.

Transits of Venus are rare, occur in pairs eight years apart and then not recur over a hundred years later. The last was 2004 and after this, that completes the pair, experts estimate that there will be another until 2117.

NASA planned to begin at 22:09 GMT and is expected to have a duration of seven hours.

The entry is expected to occur between 22:09 and 22:27 GMT on June 5 and depart between 4:32 and 04:50 GMT.

Araujo encouraged to participate in any activity that NASA centers, planetariums and scientific organizations have been organized throughout the world to see this unique spectacle.

Although, recalled that it must be done with caution and “never look at the sun with the naked eye” because it can cause anything from eye injuries or even blindness in severe cases.

Experts recommend looking through telescopes or special glasses prepared, never with normal sunglasses.

Transits of Venus captured public attention in the eighteenth century, when the size of the solar system was one of the greatest mysteries of science, NASA recalls in an article.

The relative distance of the planets was known but not their absolute distances-how many miles between us and another possible world, and Venus was the key, according to astronomer Edmund Halley deduced (1656-1742).

Halley found that observing the transit from various places on Earth, it should be possible to triangulate the distance to Venus, prompting international expeditions to survey the transits occurred in 1761 and 1769.

Other split the explorer James Cook, who was sent to Tahiti in French Polynesia today in an effort that some historians have called “the Apollo program of the eighteenth century.”

NASA says that the experiment, in retrospect, it sounded better than it was the result, because the bad weather in some places of observation and the limitations of primitive instruments caused “confusion” on the actual density of the atmosphere of Venus and other data.

A late nineteenth century, astronomers, with modern instruments and cameras, finally managed to measure the size of the solar system as Halley had suggested to the data of registered transits in 1874 and 1882.

Now scientists at the twenty-first century, with satellites in space and better cameras than ever, hoping to study hundreds of phenomena as the behavior of extra solar planets in the search for life in the universe.
