New "persecution of Christians" have launched worldwide


New "persecution of Christians" have begun worldwide, especially in Muslim states, particularly in the Middle East where Christians are essentially threatened with extinction. 200 million Christians, about 10% of Christians worldwide, "dealt disadvantaged in society, harassed or oppressed actively for their beliefs."
H Civitas, the famous British "think tank" for the civil society,  adopted recently an extensive study on " Christianophobia ", signed by Rupert Shortt, scholar, editor of The Times Literary Supplement and fellow of Blackfriars Hall, Oxford. The study makes it clear that Christians worldwide suffer more hostility than any other religious group, while politicians appear essentially "blind" before the extent of violence against Christians in Africa, Asia and the Middle East. Among half to two thirds of the Christians of the Middle East have been forced either to migrate or killed during the last century, leaving the land where Jesus was born without Christians. Apart from violent attacks, killing and plunder, the study notes that "Christians who say their religious beliefs are employed in public services find their professional advancement virtually impossible." Recall that in Britain, where the research was published there have been cases of Christians who even threatened with dismissal because pectoral cross worn when working in the public and private sectors.
Often the persecution and "Christianophobia" relate to fears of authoritarian regimes that Eastern Christianity is a "Western belief" that aims to katavarathrosi them. And contributed to this wasteful use of the term "Crusade» (crusades) by George W. Bush, creating the feeling that one is imminent coordinated attack of Christianity on Islam, which had to fight back.
The state prosecution of Christianity occurs in greater China, where more Christians imprisoned than anywhere else in the world, says the UK Telegraph.
The actual hostility against Christians is constantly growing, and unfortunately help the "Arab Spring," which brought more assertive Islamic political forces in things. The study recorded hundreds of cases of attack by fanatics against Christians, mostly in Egypt, Iraq, Pakistan, Syria, Nigeria, Burma and China.
The only Christian minister in Pakistan, the Catholic Shahbaz Bhatti, was assassinated last year. The Telegraph carries that after the murder was videotaped message with the words: "I prefer to die for my principles and for the justice in my community rather than to compromise. Share with you that I believe in Jesus Christ, who gave his life for us. "
The Primate of the Orthodox Church, the Syrian Patriarch of Antioch and All the East John of Damascus called all Christians to remain in Syria despite the continuation of the civil war. In his first speech after his election called on the warring parties to end the conflict. In audiovisual message posted on the internet, dissidents threatened to attack two Christian villages where residents do not prosecute government troops there.
Note that the politicians in the western world or icily indifferent to religious genocide taking place on a large scale, as demonstrated by the study of Shortt, or fear that any expression of concern will be featured racist, brandishing political cost.

COMET ISON




ΜΑΛΟΝ ΤΟ ΤΕΛΟΣ ΤΟΥ ΚΟΣΜΟΥ ΑΝΑΒΛΗΘΗΚΕ ΓΙΑ ΛΙΓΟΥΣ ΜΗΝΕΣ!
In 2013 a comet called Ison will put on a once in a lifetime show. The comet is expected to be visible to the naked eye for several months in late 2013, and could at times be brighter than the Moon.
It will be visible from all around the world.


At the moment it is a faint object, visible only in sophisticated telescopes as a point of light moving slowly against the background stars. It doesn't seem much – a frozen chunk of rock and ice – one of many moving in the depths of space. But this one is being tracked with eager anticipation by astronomers from around the world, and in a year everyone could know its name.
Comet Ison could draw millions out into the dark to witness what could be the brightest comet seen in many generations – brighter even than the full Moon.
It was found as a blur on an electronic image of the night sky taken through a telescope at the Kislovodsk Observatory in Russia as part of a project to survey the sky looking for comets and asteroids – chunks of rock and ice that litter space. Astronomers Vitali Nevski and Artyom Novichonok were expecting to use the International Scientific Optical Network's (Ison) 40cm telescope on the night of 20 September but clouds halted their plans.


It was a frustrating night but about half an hour prior to the beginning of morning twilight, they noticed the sky was clearing and got the telescope and camera up and running to obtain some survey images in the constellations of Gemini and Cancer.
When the images were obtained Nevski loaded them into a computer program designed to detect asteroids and comets moving between images. He noticed a rather bright object with unusually slow movement, which he thought could only mean it was situated way beyond the orbit of Jupiter. But he couldn't tell if the object was a comet, so Novichonok booked time on a larger telescope to take another look. Less than a day later the new images revealed that Nevski and Novichonok had discovered a comet, which was named Comet Ison. A database search showed it has been seen in images taken by other telescopes earlier that year and in late 2011. These observations allowed its orbit to be calculated, and when astronomers did that they let out a collective "wow."
Comet Ison has taken millions of years to reach us travelling from the so-called Oort cloud – a reservoir of trillions and trillions of chunks of rock and ice, leftovers from the birth of the planets. It reaches out more than a light-year – a quarter of the way to the nearest star. In the Oort cloud the Sun is but a distant point of light whose feeble gravity is just enough to hold onto the cloud. Every once in a while a tiny tug of gravity, perhaps from a nearby star or wandering object, disturbs the cloud sending some of its comets out into interstellar space to be lost forever and a few are scattered sunward. Comet Ison is making its first, and perhaps only visit to us. Its life has been cold, frozen hard and unchanging, but it is moving closer to the Sun, and getting warmer.
Ison's surface is very dark – darker than asphalt – pockmarked and dusty with ice beneath the surface. It's a small body, a few tens of miles across, with a tiny pull of gravity. If you stood upon it you could leap 20 miles into space taking over a week to come down again, watching as the comet rotated beneath you. You could walk to the equator, kneel down and gather up handfuls of comet material to make snowballs, throw them in a direction against the comet's spin and watch them hang motionless in front of you. But it will not remain quiet on Comet Ison for the Sun's heat will bring it to life.
By the end of summer it will become visible in small telescopes and binoculars. By October it will pass close to Mars and things will begin to stir. The surface will shift as the ice responds to the thermal shock, cracks will appear in the crust, tiny puffs of gas will rise from it as it is warmed. The comet's tail is forming.
Slowly at first but with increasing vigour, as it passes the orbit of Earth, the gas and dust geysers will gather force. The space around the comet becomes brilliant as the ice below the surface turns into gas and erupts, reflecting the light of the Sun. Now Ison is surrounded by a cloud of gas called the coma, hundreds of thousands of miles from side to side. The comet's rotation curves these jets into space as they trail into spirals behind it. As they move out the gas trails are stopped and blown backwards by the Solar Wind.
By late November it will be visible to the unaided eye just after dark in the same direction as the setting Sun. Its tail could stretch like a searchlight into the sky above the horizon. Then it will swing rapidly around the Sun, passing within two million miles of it, far closer than any planet ever does, to emerge visible in the evening sky heading northward towards the pole star. It could be an "unaided eye" object for months. When it is close in its approach to the Sun it could become intensely brilliant but at that stage it would be difficult and dangerous to see without special instrumentation as it would be only a degree from the sun.
Remarkably Ison might not be the only spectacular comet visible next year. Another comet, called 2014 L4 (PanSTARRS), was discovered last year and in March and April it could also be a magnificent object in the evening sky. 2013 could be the year of the great comets.
As Comet Ison heads back to deep space in 2014 the sky above it would begin to clear as the dust and gas geysers loose their energy. Returning to the place where the Sun is a distant point of light, Comet Ison may never return. Its tail points outward now as the solar wind is at its back, and it fades and the comet falls quiet once more, this time forever.
