There is something very peculiar about
watching a shooting star, as the effect it has on people greatly varies from individual to individual
and from culture to culture. The understanding of the shooting star in
different parts of the world is both varied and suggestive. Thus, westerners often make a wish when they
see a falling star, while in other parts of the globe, any shooting
star tells people that someone has passed away. Yet,
even if popular beliefs give
different explanations to these cosmic phenomena, 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 over here for more

A shooting star is a meteoroid, or some form of
debris that enters
Earth’s atmosphere and gets on fire. The friction of
the air masses, the ram pressure 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 making smaller or larger craters. Such falling stars are known as 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
only at night, meteoroids and meteors also fall during
the day, but this time they can be
identified only by radio signals, with the sunlight making them very difficult to spot
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. You

A shooting star with a high burning intensity is called a
fireball and the measurements are made by comparing the light intensity of
the meteor with that of a planet. As beautiful
as it may look, a shooting star has a huge
destructive potential if it is not totally burned during the
flight through the atmosphere. Past collisions proved
devastating for ecosystems, with great flora and fauna damage; should such a shooting star fall in a city,
the impact would be that of a bomb dropping, with
the intensity of the explosion varying according to the size of the meteorite. You should
