Quadrantid Meteor Shower January 4, 2012

With clear skies rock and lunar stage the western sky watchers in Acadiana can handle a demanding meteorites night after midnight … position very welcome! The Quadrantid meteor shower is one of the best in the twelve months is often more than a hundred meteors per minute from a brilliant near the North Star. Storms tend to stay cold and privileged observers. Located between the constellations Bootes and Draco, NASA says the Veterans Quad early astronomical instrument used to observe the stars and symbolize plot.

A meteor shower is a celestial event where a number of meteors observed that radiate from a point in the night sky. These meteors are caused by streams of cosmic debris called meteoroids enter Earth’s atmosphere at very high speeds on parallel tracks. Unusual meteor showers are known as meteor outbursts and meteor storms, which can lead to more than 1,000 meteors per hour. [1]

Because meteor shower particles are all traveling in parallel paths, with the same speed, they all seem to an observer below to radiate from a single point in the sky. Meteor showers are almost always the name of the constellation from which meteors appear to emerge. The radiant also moves slightly from night to night against the background stars (radiant drift) due to the Earth moves in its orbit around the Sun See the “IMO” Meteor Shower Calendar 2007 (International Organization Meteor) for maps of drifting “fixed points”. The Working Group International Astronomical Union Nomenclature of meteors and meteorites Rain Data Center of the IAU nomenclature maintain and meteor showers are.

A meteor shower is the result of an interaction between a planet like Earth, and the waste streams of a comet. The “stone” can vary in size from a speck of dust to a small stone. When heated ice sublimates and vapor can drag along dust, sand and pebbles. Each time a comet changes by the Sun in its orbit, some of its ice evaporates and a degree of meteors was shed. The meteoroids spread along the comet’s orbit to a stream of meteors, also known as “dust tail” (as opposed to a “dust tail” comet caused by very small particles that are quickly swept away by the pressure as solar radiation).
