artiarThe beauty of a shooting star crossing the night sky is undeniable, but while for some people this is very romantic, for others it just suggests a bad omen. The perception of the shooting star in different parts of the world is both varied and suggestive. Thus, westerners commonly make a wish when they see a falling star, while in other traditions, any shooting star represents a sign that someone dies. Yet, although we give all sorts of explanations to such sky events, they have a very reasonable and easy to understand scientific background. Beautiful and great as a shooting star may be, it is just a false star. Click through here for more information relating to star sign compatibility.
A shooting star is a meteoroid, or some other boulder-sized debris form that enters Earth’s atmosphere and gets on fire. The great friction of the air masses and the presence of the oxygen associated with the high velocity of the meteoroid cause the star-like appearance. Thus, the combustion of the shooting star is complete before reaching the surface of the planet. Larger meteoroids that don’t burn completely because of their size fall on the ground causing crater formations. This time they are called meteors.
Scientists can identify the chemical structure of a shooting star by observing the light specter during the descent as well as the trajectory through the atmosphere. Though observable with the naked eye on the dark night sky only, meteoroids and meteors have been reported during the day, but this time they can be identified only by radio signals, with the sunlight preventing their observation otherwise. Thus, scientists have concluded that a shooting star can be light and fragile like a snowball or heavy and dense because of the hard metal core. A special kind of shooting star here is the one that passes through an atmosphere sector and gets out into space again to continue its speedy course.

A shooting star with a high burning intensity is called a fireball and the measurements result from comparing the light intensity of the meteor with the light normally reflected by a planet. As beautiful as it may look, a shooting star has a huge destructive potential if it is not totally combusted during the passage through the atmosphere. Past collisions proved devastating for ecosystems, with vegetation and animal losses; should such a shooting star fall in a city, the impact would be that of a bomb attack, with the intensity of the explosion varying according to the size of the meteorite.
