A comet 15 times brighter than Moon to dazzle Earth

A comet 15 times brighter than Moon to dazzle Earth

LONDON: A comet which shines 15 times brighter than the moon and potentially visible in broad daylight will fly by the Earth next year, giving humans a chance to witness one of the most spectacular events. Comet ISON is visiting the inner solar system and is set to put on spectacular views for the Northern Hemisphere across November and December in 2013 as it heads toward the sun, the Daily Mail reported.
The comet, discovered by astronomers in Russia using the International Scientific Optical Network telescope, will pass within two million miles of the sun's surface.
The comet is supposed to be on a 'parabolic' orbit which means it originated from the outer skirts of the solar system from the Oort cloud - a mass of icy debris which lies 50,000 times further from the sun. It is currently moving inwards from beyond Jupiter, and as it approaches Earth, it could produce a dazzling display.

Nazi-backed venture in part to trace origins of Aryan race
An ancient Buddhist statue that a Nazi expedition brought back from Tibet shortly before World War II was carved from a meteorite that crashed on Earth thousands of years ago.
What sounds like an Indiana Jones movie plot appears to have actually taken place, according to European researchers publishing in the journal Meteoritics and Planetary Science this month.
Elmar Buchner of the University of Stuttgart has said the statue was brought to Germany by the Schaefer expedition. The Nazi-backed venture set out for Tibet in 1938 in part to trace the origins of the Aryan race — a cornerstone of the Nazis’ racist ideology. The existence of the 10.6-kg statue, known as “iron man”, was only revealed in 2007 when its owner died and it came up for auction, he told AP.
German and Austrian scientists were able to get permission from its new owner, to conduct a chemical analysis that shows the statue came from the Chinga meteorite, which crashed in the area of what is now the Russian and Mongolian border around 15,000 years ago.
The meteorite was officially discovered in 1913, but Mr. Buchner said the statue could be 1,000 years old and represent a Buddhist god called Vaisravana. The Nazis were probably attracted to it by a left-facing swastika symbol on its front.
Scientists said the research linking the statue to the meteorite was credible.
“Looks like a solid piece of geochemical ‘forensic’ work,” said Qing-Zhu Yin, a researcher in geology at the University of California, Davis. “No terrestrial artefact would generally contain that much nickel content. Chemical elements don’t lie.”
Rhian Jones, an associate professor at the University of New Mexico who specialises in meteorites, said the claim appeared conclusive. But Mr. Yin cast doubt on the claim that the statue represented a Buddhist deity. “I am not a historian. But the ‘iron man’ does not look like a Buddha to me from my cultural background,” he said. “It looks more like a warrior with a sword ... (a) resemblance of Genghis Khan. ... I have never seen a Buddha with a sword or knife.”

Global warming could be combatted with asteroid dust acting like a sunshade for earth, scientists say

Global warming could be combatted with asteroid dust acting like a sunshade for earth, scientists say

  • Scottish scientists believe an asteroid could be maneuvered into position before a cloud of dust is blasted from the surface
  • Because an asteroid has its own gravitational pull, the dust would be anchored in place

Scottish scientists have come up with an intriguing new idea to combat global warming - blasting the surface of asteroids to create giant clouds of dust which would act as sunscreen for the planet.
Researchers at the University of Strathclyde believe a suitably sized asteroid could be moved into a position close to earth before a giant cloud of dust is blasted off its surface.
And because an asteroid creates a gravitational pull, the dust is held in position rather than being gradually dispersed across space.

The idea is the latest in a series of ambitious projects, known as geoengineering, which aim to alter the climate of the planet by reflecting, diverting or absorbing solar radiation. 
 

Research by he United Nations' Intergovernmental Panel on Climate Change suggests average global temperatures will increase by between 1.1C and 6.4C by the end of this century.
Russell Bewick, one of the research team at the University of Strathclyde told Live Science: 'People sometimes get the idea of giant screens blocking the entire sun.
'This is not the case ... as [the device] is constantly between the sun and the earth, it acts merely as a very light shade or filter.'
'I would like to make it clear that I would never suggest geoengineering in place of reducing our carbon emissions.
The asteroid would be moved into position at what is known as Lagrange point L1, a point in space where the gravitational pull of the Sun and the Earth balance each other out

'We can buy time to find a lasting solution to combat Earth’s climate change. The dust cloud is not a permanent cure, but it could offset the effects of climate change for a given time to allow slow-acting measures like carbon capture to take effect.'
An earlier proposal to shade Earth from the sun involved placing giant mirrors in space.
However this is seen as impractical due to the massive cost of building the giant mirrors and blasting them into orbit or constructing them in outer-space.
Another idea involved using blankets of dust to blot out the sun in the same way clouds do on earth.
However while this would be considerably cheaper than placing mirrors in space it is believed the dust would be dispersed due to the gravitational pull of the sun, moon and other planets.
So the Scottish team came up with the novel idea of using an asteroid's own gravitational pull to effectively anchor the cloud of dust and stop it drifting away.
The asteroid would be placed at what is known as Lagrange point L1, a point in space where the gravitational pull of the sun and the Earth balance each other out. L1 is about four times the distance from Earth to the moon.
The asteroid would be fitted with a 'mass driver,' powerful electromagnets that, as well as acting as an engine to maneuver the asteroid into position, could also blast a cloud of dust away from its surface.
The researchers have identified the largest near-Earth asteroid, 1036 Ganymed, as a suitable candidate.
They believe Ganymed could generate a dust cloud large enough to block out 6.58 per cent of solar radiation reaching earth, more than enough to combat any current levels of global warming.
The dust cloud generated would be about 5 quadrillion (5,000,000,000,000,000) kilograms in mass and about 1,600 miles wide.
The research team, from the University of Strathclyde, estimate a suitably-sized asteroid could generate a dust cloud large enough to block out 6.58 per cent of solar radiation reaching earth

Mr Bewick said: 'A very large asteroid is a potential threat to Earth, and therefore great care and testing would be required in the implementation of this scenario.
'Due to this, the political challenges would probably match the scale of the engineering challenge. Even for the capture of much smaller asteroids, there will likely be reservations from all areas of society, though the risks would be much less.'
The main challenge for the scientists is finding a way of moving such a large asteroid into place.
Mr Bewick added: 'The company Planetary Resources recently announced their intention to mine asteroids.
'The study that they base their plans on reckons that it will be possible to capture an asteroid with a mass of 500,000 kilograms by 2025.
'Comparing this to the mass of Ganymed makes the task of capturing it seem unfeasible, at least in everything except the very far term.
'However, smaller asteroids could be moved and clustered at the first Lagrange point.'

Srinagar, Sep 30: The internet-service-providing companies have blocked social networking sites including Facebook and YouTube in Kashmir without any official directive the state government.
 The cellular companies have also blocked GPRS facilities on the mobile telephones causing immense inconvenience to the subscribers.
 Greater Kashmir received over a dozen telephone calls from different areas of the Valley, complaining that the internet service has been blocked by companies including BSNL, Reliance, Aircel, Airtel and Vodafone.
 “The service is completely down. Apart from jamming the social networking sites, the companies have started to put restrictions on general use like e-mails and on search engines as well,” the callers said.
 They said their internet devices and GPRS service on mobile is not functioning in the wake of jamming of the service by the concerned cellular companies.
 A delegation of businessmen Sunday said the BSNL service on Blackberry was also jammed. “Never has it happened in the past. We are facing huge problems in the communication due to the slow functioning of the service. We had also enquired from the officials of the BSNL but they are not taking our word seriously,” the delegation said.
 General Manager Reliance (J&K) Ataullah Haque told Greater Kashmir that every company has jammed Facebook and YouTube but the rest of the services were functioning.
 “Basically government has issued a directive to block the Facebook but other services are functioning,” he said.
 Asked was the company in possession of the “official directive,” the GM said the document would be with the regulatory department of the company.
 When contracted, a top BSNL official said the services have been disrupted on the directions of the State Government.
 “We have blocked all the websites and services according to the government directive. Blackberry services have also been stopped,” he said.
 However, Minister for Information Technology, Aga Ruhullah has said there is no ban on Facebook and Youtube.
 “There is not any ban on these websites. I don’t have proper information of it. I can’t confirm whether there is any technical snag in it,” Ruhullah said.

Complete biography of K. Kamaraj


Complete biography of K. Kamaraj
"Face the problem. Don't evade it. Find a solution, however small. People will be satisfied if you do something."
On July 15, 1903, in a tiny town of Virdunagar, Tamil Nadu, and a little baby boy was born. His parents Kumaraswamy Nadar and Sivakami Ammal named him Kumaraswamy Kamaraj Nadar.
Kamaraj's father, Kumarswamy Nadar, who belonged to a family of traders, was a coconut merchant who sold and traded coconuts for a living. Their family was not rich and Kamaraj, right from his babyhood led a simple and a humble life. Kamaraj's mother Sivakamitada soft corner for her little son and called him "Raja" affectionately.
When Raja turned three, she enrolled him at the local elementary school, the Nayanar Vidyalaya close to his home. By and by he was shifted to a bigger school Kshatriya Vidyalaya, which provided high schooling at that time.
But tragedy struck their family. His father died unexpectedly within a year of Kamaraj's enrollment in school. His peaceful life was thoroughly disrupted, as there was no other earning member in the house.
Following his fathers death, Kamaraj fearfully asked his mother, "What are we going to do for a living, mother?"
Kamaraj's mother Sivakami, a woman of great determination replied, "I will sell all the jewellery I have and sustain you my dear Raja. Why do you worry? You will continue to go to school".
Thus, she sold all the jewels she had except her earrings. She deposited the money with a local Merchant and cared single handedly for the entire family on the monthly interest that the money earned.
Kamaraj was not a good student in school and dropped out when he was twelve years old. Thus his schooling lasted only for a few years. His relatives scolded him for his slackness.
One day Karuppiah, his maternal uncle called him aside and said, "Kamaraj you are so backward in studies. You might as well join me as apprentice in my cloth shop. I think that is the best thing for you."
Kamaraj readily agreed for the change.
When he was 15 years of age, the Jallianwala Bagh massacre took place in the country where the British as a sign of resentment towards the Indian freedom struggle, opened fire killing hundreds of innocent people. When Kamaraj heard this, he was touched and furious.
He told himself,” I will not sit quiet. I will join in India's struggle for freedom." The massacre was the turning point in his life.
Little Kamaraj loved to attend public meetings addressed by orators like Dr. Varadarajulu Naidu and George Joseph for the cause of the freedom struggle He would slip out from his uncle's shop to join processions and attend the meetings.
His relatives frowned upon Kamaraj's budding interest in politics and frequently chided him. They sent him to Thiruvananthapuram to work at another uncle's clock shop. But even in Thiruvananthapuram Kamaraj's fire for the country's freedom could not be quenched. There he participated in the Vaikom Satyagraha led by George Joseph of the Congress, against the atrocities of the higher caste Hindus on the Harijans much to the annoyance of his family.
Two years later when Kamaraj was seventeen, he saw Gandhiji at Madurai. He was struck by his simplicity and his non-violent attitude towards India's freedom struggle.
His relatives called him aside and said, "Kamaraj politics is not good for you. It is time you get married and settle down. You will be happy then."
But Kamaraj was stubborn and he declared his decision, "This is the path that I will choose. Please do not stop me. I will not get married."
Thus Kamaraj resolutely refused to bow to the dictates of his elders. And at such a young age he became a dedicated member of the Indian National Congress and enrolled himself as full-time worker.
Kamaraj was content for years to remain a Congress volunteer, working hard for the cause of the freedom movement. He was neither worried of his personal comfort nor did he care for higher placements in his career
When Kamaraj was 18, Gandhiji started the non-cooperation movement against the British. Kamaraj was one of the first to respond. He carried on the Propaganda in the villages, raised funds for Congress Work and took a leading part in organizing meetings.
Satyamurthy, one of the greatest orators and a fading figure of the Tamilnadu Congress Committee met Kamaraj when he was twenty. Later on he turned out to be Kamaraj's political guru and main source of inspiration.
Satyamurthy praising Kamaraj said, "He is the most efficient, loyal, indefatigable worker and skillful organizer I have ever seen"
Both of them developed a deep friendship and complemented each other's skills very well. They made a great team together much to the delight of the Congress leaders.
In April 1930, Kamaraj joined the Salt Satyagraha Movement at Vedaranyam. The British government sentenced him to two years of imprisonment for his active participation. This was his first term in prison. He was 27 at the time of arrest.
Following this, Kamaraj was implicated in the Virudhunagar Bomb Case two years later. Dr. Varadarajulu Naidu and George Joseph, who by then knew the faithful little boy who attended every one of their meetings, argued on his behalf and proved the charges to be baseless.
But his jail going did not stop there. It almost became a part of his career. He was arrested now and again, and in all he went to prison six times and spent more than 3,000 days in British Jails.
When he entered mainstream politics, he felt handicapped and realized the importance of a good education.
But Kamaraj who was strong-minded decided, "I will not feel sorry for myself. I shall start studying again."
Thus, he educated himself during his periods of imprisonment and even learned English from his co­worker.
While still in jail, Kamaraj was elected Chairman to the Municipal Council. Nine months later upon his release, Kamaraj went straight to the Municipality and tendered his resignation from his post.
When people asked him why he did so, he calmly replied "one should not accept any post to which one could not do full justice."
When Kamaraj was 33, Satyamurthy, his good friend and guru was elected President of the Provincial Congress. Following this he appointed Kamaraj as the General Secretary. Four years later they swapped positions. The party base was very much strengthened under their leadership.
When Kamaraj was 38, Gandhiji asked him to spread propaganda material for the Quit India movement. He was arrested once more on that account and was sentenced to three years in the Amaravath' prison. While in prison, his spirit was not deterred .read books and continued his self-education within the four walls.
Kamaraj kept his word and remained a bachelor throughout. He chose not to marry, as he was fully dedicated to the country's freedom struggle movement. Finally his efforts did pay off and when he was forty- four years of age, India became free.
By then, Kamaraj's guru Satyamurthy had already passed away. So deep was Kamaraj's devotion for him that when India gained independence, he first went to Satyamurthy's house and hoisted the Indian flag there.
On April 13, 1954, K. Kamaraj was elected the Chief Minister of Madras. To everyone's surprise, Kamaraj nominated C. Subramaniam and M. Bhakthavatsalam, who had contested his leadership, to the newly formed cabinet.
Kamaraj gave simple advice to his ministers, "Face the problem. Don't evade it. Find a solution, however small. People will be satisfied if you do something."
Under Kamaraj's guidance, the State made immense strides in education and trade. New schools were opened-, better facilities were added to existing ones. No village remained without a primary school and no panchayat without a high school. Kamaraj himself, though hardly attended school, did not stop in striving to eradicate illiteracy. He introduced free and compulsory education up to eleventh standard.
He introduced the Midday Meals Scheme to provide at least one meal per day to the lakhs of poor children. He introduced free school uniforms to weed out caste, creed and class distinctions among young minds.
Kamaraj was a firm believer of Gandhiji's principles. He said, "Mahatmaji not only spread the message freedom to the farthest comers of India, but also devoted his attention to the eradication of poverty and misery among the masses. That's is what I intend to do"
During Kamaraj's administration, a number of irrigation schemes were completed in record time. The Land Ceiling Act and the Tenancy Protection Act benefited small farmers and saved them from being exploited by landlords. Medium and small scale industries prospered in the midst of large industries making Madras one of the leaders in industrialization.
Nehru who was the Prime Minister then complimented Kamaraj saying, “Madras (renamed State of Tamil Nadu) is the best administered State in India."
Kamaraj remained Chief Minister for three consecutive terms. On October 2, 1963, almost nine years since he had become the chief minister, he resigned his post to serve a greater purpose. He noticed that the Congress party was slowly losing its vigor and came up with a plan, which was called the "Kamaraj Plan."
He proposed that all senior Congress leaders should resign form their posts and devote all their energy to the re-vitalization of the Congress. A number of Central and State ministers like Lai Bahadur Shastri, Jagjivan Ram, Morarji Desai and S.K. Patil followed suite and resigned from their posts. Kamaraj was then elected the President of the All India Congress and he successfully navigated the nation through the stormy years following Nehru's death.
On October 2, 1975, the day celebrated as Gandhi Jayanti, Kamaraj awoke from his afternoon nap feeling uneasy. He was 72 years of age,
His housekeeper, Vairavan worried said, "I will bring in the physician sir."
While he was on his way out, Kamaraj said, "Vairavan, put out the lights when you go out."
K. Kamaraj died before he came back. He was honoured with the highest civilian honor, the Bharat Ratna, posthumously in 1976.
He was perhaps the first non-English knowing Chief Minister in India. But it was during the nine years of his leadership that Tamilnadu came to be known as one of the best administered States in India.
