Damage Ozone Hole Covering an area of ​​North America

 Damage to the ozone layer at the South Pole reached an area of ​​27 million square kilometers. That breadth is greater than the breadth of North America about 25 million square kilometers.

''This happens because a lot of human behavior that unwittingly cause damage to the ozone,''said Head of Atmospheric Science and Technology Institute of Aeronautics and Space Agency (LAPAN), Novita Ambarsari, told reporters on the sidelines of the socialization of the Protection of the Ozone Layer in Armed Pusdik, Cimahi, Monday (4 / 7).

South Polar ozone hole is not in the sense that the actual hole in the ozone layer. However, said Novita, the ozone hole is a thinning of the ozone layer with a lower concentration of 220 DU. This value is based on observations of ozone at the South Pole which is never higher than 220 DU since 1979.

Meanwhile, based on data of total ozone measurements Nimbus satellite in June 2009, there are trends of decrease in total ozone concentrations in Indonesia amounting to 0.29 DU / year. Chemicals damaging the ozone layer is primarily derived from the type of chlorofluorocarbons (CFCs) used in various processes of products such as refrigerators, air coolers, and soft foam manufacturing processes as cleaning fluid.

"Materials ozone depleting substances are widely used in industrial fire extinguishers and Methyl Bromide used for pesticide ingredients,''said Novita.''Use of these materials increased rapidly since the 1970s that led to abortion in the atmosphere also increases."

He said how to resolve this problem by altering human behavior. Communities should be made aware that human beings should live longer with a comfortable and safe atmosphere. Education can be delivered in the form of stories and tangible evidence that people moved to live with a better way.

"A lot of people's habits is never an appropriate pattern back to nature such as turn on the TV without anyone watching it. In fact, the electricity comes from solar energy. Meanwhile, diesel fuel can not be updated and burns itself causes damage to the ozone layer," he said. 

This is the Origin of UFOs

On June 24, 1947, amateur pilot Kenneth Arnold flew a small airplane near Mt Rainier, Washington and saw a very odd-shaped objects. What is it?

It was located right on the left side of Arnold, 20-30 km north of the plane at the same altitude. It was a series of nine objects flying toward the sun shining over. Comparing the size of the plane, Arnold estimate the size of the object was as wide as 13-15 m.

Given this thing is capable of flying as far as 80 miles in 1 minute 42 seconds, Arnold is able to estimate the object traveling at the speed of 2736 km / h or three times faster than man-made aircraft that era.

However, as if controlled, flying objects that seem dipped and swerved around obstacles in the terrain. When these things disappeared in the distance, Arnold flew to Yakima, Washington, then landing and immediately tell the airport staff.

The next day, Arnold interviewed by journalists, and stories about it spread like fire across the nation. "At that time, there is still a presumption, Mars or Venus could be a new residential planet," says author Robert Sheaffer UFOs.

People think, this UFO is a Martian who came watching people who now have nuclear weapons, he added. Over time, the incident that is the theory first of many visits that is outer space. The era of UFO sightings began.

Arnold's sighting a "kind of sensation that made ​​headlines around the world, 'writes Martin Kottmeyer UFO expert. "Soon after, everyone is looking for a new airplane shaped like a plate," he continued.

In recent weeks, reports emerged of hundreds of objects flying around the world. While people thought the same thing with Arnold's view, there is a great irony that time. Namely, "Kenneth Arnold reported seeing flying saucers have not."

In fact, Arnold told the press, it was flying erratically, "As if the plate across the water". This thing is thin and flat when viewed from the end, he said. However, a crescent-shaped when viewed from above. However, reporter Bill Bequette of United Press interpreting, disc-shaped object was round.

According to UFO expert and deputy editor of Skeptical Inquirer Benjamin Radford, "The statement was to be one the greatest quotes in history to be a journalist". The phrase 'flying saucer' giving shape to the myth of UFOs from the beginning, writes Kottmeyer.

In the eyes of art, hoax, science fiction movies, tv shows and most reports alien abductions, UFOs described as flying saucers today. "Error Bequette himself unable to refutation of the theory of space for everyone. However, this error even leave a great paradox, Why would extraterrestrials redesign their aircraft to conform to Bequette's error? "Wrote Kottmeyer.

Although not see flying saucers, mostly co-pilot was convinced Arnold really see anything that day. So, what Arnold actually see? One theory holds, Arnold saw a fireball, meteor falling from the atmosphere. Furthermore, pieces of meteors will be tangible such as chains and shines very brightly and could move thousands of kilometers per hour.

However, many historians thought it was not bendar outer space, "It was probably only the pelicans flying in formation," said Sheaffer. Maybe Arnold misjudged the distance and thought things were great and are in great distances, but real close, he added.  

Crop Circle in East Jakarta

Beginning this May, the news spread that found certain patterns in the area of ​​rice fields in the City of Delta Mas, Cikarang, West Java. Cikarang crop circle was not soured similar findings in Sleman, January.

But last weekend, enlivened Kaskus forum discussions around video crop circle Cikarang. Description of the video on YouTube says the picture is taken from a camera mounted on a miniature helicopter that is controlled remotely.

Although often associated with UFOs, but some crop circles are works of art created by artists. Directions to make any crop cirle easily found on the Internet.

ADDITIONAL:
So, who's making crop circles in Cikarang it? According Okezone, it turned out to property filming! Now, rice at the site is back as usual. "It's been harvested. Once it is paid for the purposes of filming," said Mrs. Adi, a food vendor near the site.

Rice cultivators, said Mrs. Adi, paid Rp 200 thousand on 4 May, when filming was held.

Dawn spacecraft asteroid Vesta Approach

After a 3.5-year interplanetary journey, unmanned spacecraft, Dawn, began to approach his first destination, the asteroid Vesta. This vehicle is planned to be an end to journey into the solar system objects in the asteroid belt, namely the dwarf planet Ceres in 2015.

Aviation and Space Agency for the United States (NASA) announced last May 3, the Dawn spacecraft, launched from the U.S. Air Force Base, Cape Canaveral, Florida on September 27, 2007, starting near Vesta. Now, Dawn is just 1.21 million kilometers of Vesta and have traveled 4.8 billion kiometer from Earth.

The primary mission of this spacecraft is to collect information on two objects in the asteroid belt, Vesta and Ceres ie. Asteroid belt is a region that is rich asteroids between Mars and Jupiter.

If all plans went well, the engine driver of a vehicle will start to enter the orbit of Vesta on 16 July. When Dawn reaches a height of 16,000 km from the surface of Vesta, the vehicle will be caught by the gravity of Vesta.

Dawn will orbit Vesta for about one year. A number of instruments in the spacecraft will collect various data of this asteroid from its chemical composition, shape and texture of the surface topography, until the force of gravity.

VIDEO: UFO War in Heaven There's San Diego?

Visible movement of celestial objects in the night sky. UFO War?

Ed Grimsley, observers UFO (Unidentified Flying Object) and founder of the UFO community of Night Vision Sky Watch, record the 'sightings' UFO on April 30, 2011.

In a recording made ​​in San Diego, California, United States, the visible movement of celestial bodies.

The movement was a point that moves closer to another point, as in the circumstances to attack. Occasionally, visible also point away from the other point, such as trying to avoid the attack.

Ed Grimsley and his friends thought it was a UFO movement. In fact, they mention that the movement of a number of points showed no war is like a UFO. 


However, it has not obtained an astronomical explanation of the movements of a number of points that space. Not yet known whether there is movement of stars, meteors or other celestial body is massive in the night when Ed was recording.

Curious what the movement of celestial body in question? See the video.

Revealed, Human Ancestors More Similar Cow

London - The latest anthropological studies revealed that human ancestors, Paranthropus boisei, proved to have a cow-like behavior than ordinary people.

Previously, there were estimates, strong jaw Paranthropus boisei used to eating nuts, seeds, and fruits. Now, the results of recent studies indicate Paranthropus boisei teeth used to cut and eat the grass in large quantities.

"We did not expect to find berkebiasan primates eat like a cow in the family tree of human ancestors," said Professor Matt Sponheimer of the University of Colorado Boulderdi United States (U.S.).

Paranthropus boisei is part of the human lineage brother, known as australopithecines. Fossil australopithecines comes from Ethiopia and an estimated three million years old. This fossil is also known as Lucydan alleged 'modern ibu'manusia.

About two and a half million years ago, the australopithecines are divided into two two groups, namely homo sapiens (modern humans beginning) and type Paranhropus who later became extinct. The first fossil Paranthropus boisei or 'Nutcracker Man'ini discovered in Tanzania in 1959.
