So called great comet

I had no idea that the brightest comet in 30 years was sweeping across the sky, before it already was beyond the horizons of the northern hemisphere. Luckily, fellow gazers in the south keep on
posting amazing photos to Flickr.
A comet discovered in August 2006 by Robert H. McNaught became the “Great Comet of 2007″ a bit of a sudden. Comets this spectacular are tricky snowballs on extreme orbits (McNaught is not expected to return for thousands of years), so every visit is unique on human timescale – and almost every visit unprecedented in recorded history.
The legendary Halley’s Comet is the best known exception. With an orbital period of 75 years, it is the only comet “guaranteed” to appear within a lifetime. Since its first predicted fly-by in 1758, it has become a “cultural event that links generations”.
Mark Twain had special connection to Halley’s Comet, his lifetime took place exactly between two appearances of the comet:
I came in with Halley’s Comet in 1835. It is coming again next year, and I expect to go out with it. It will be the greatest disappointment of my life if I don’t go out with Halley’s Comet. The Almighty has said, no doubt: “Now here are these two unaccountable freaks; they came in together, they must go out together.”
The last visit took place in the winter of 1985/86. Freezing on a hilltop the eight-year old me managed to crosshair the “cultural event” into the binocular’s field of view for about three point fourteen seconds. That visit of a lifetime coincided with the birth of my kid brother and the death of a grandfather. Later in the spring, Chernobyl exploded.
Unlike many other celestial events – a passage of a comet couldn’t be predicted by the wise of ancient cultures. Or even today’s – McNaught was discovered only five months before it went spectacular. Either this, or their eternity grazing quality has made them prime harbingers of doom. Numerous disasters have been attributed to the comets.
Even Halley’s arrival in 1910 caused panic, why? Astronomers had earlier found cyanide in another comet’s tail. As Earth was expected to pass through Halley’s poisonous tail, we all were to die. Comet Pills sold like candyfloss. Of course nothing happened – except Mark Twain died.
The first great comet of the age of www arrived in 1997. Again, it was chilly, but the sky was dark and clear. I walked down to the ice of the lake Kuortane and laid down on my back. No fear of accidentally falling asleep, because overhead loomed the spectacular Comet Hale-Bopp. Its separate dust and gas tail were clearly visible and the sky so transparent, that one could easily unlearn gravity and just fall into the stars.
Meanwhile, the cult of Heaven’s Gate had their own plans for the comet. For them Hale-Bopp was a camouflaged spaceship and its passage a solitary opportunity to reach afterlife. After 25 years of workings – they brought it all to a terrifying end, as 39 members of the cult committed a methodical mass suicide. The event shocked media internationally, President Clinton reacted on it and speculation spread in the internet. The cult had itself had used the web to recruit people and its members had built websites professionally to fund their cause.
It’s only been ten years since those events. Promisingly, so far it seems that McNaught has been received, as it is, the greatest comet for decades – nothing more, nothing less.
