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, according to reports.
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, researchers say, is supposed to be on a 'parabolic' orbit which means it probably originated from the outer skirts of the solar system from the Oort cloud which is a mass of icy debris which lies 50,000 times further from the sun than the Earth.
It is currently moving inwards from beyond Jupiter, and as it approaches the Earth, the 'dirty snowball' could produce a dazzling display, burning brighter than the moon and potentially being visible in broad daylight.
Comet ISON may prove to be brighter than any comet of the last century, visible even in broad daylight, and this may end up being its one and only trip to the solar system, as its trajectory may see it plunge into the sun in a fiery death.
Comets are dusty balls of ice, which generally originate from the Kuipler belt - a region of icy small bodies beyond Neptune. Occasionally, a comet gets dislodged from its orbit, and plunges in to the inner solar system. Halley's comet is the most well-known, named after Edmond Halley who noted the regular 75-76-year appearance of a comet, and predicted it would return in 1758. Halley's comet has passed within a fraction of the Earth before - in 1910 the Earth even moved through the comet's tail.
"This is a very exciting discovery. The comet looks like it could become a very spectacular sight in the evening sky after sunset from the UK in late November and early December next year," vice-president of the Society for Popular Astronomy Robin Scagell was quoted as saying by the paper.
"Our members will be eagerly following it as it makes its first trip around the Sun and hoping to see it shining brilliantly and displaying a magnificent tail as it releases powerful jets of gas and dust," Mr Scagell said.
