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 perception of the shooting star in

different parts of the world implies diverse meanings associated

with old beliefs sometimes. 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 dies. Yet,

even if popular beliefs give

different explanations to these cosmic phenomena, they have a very reasonable and easy to

understand scientific background. The fact is that we incorrectly call it a shooting star, as the thing in itself has nothing

of the attributes of a real star. Click over here for more

A shooting star is a meteoroid, or some form of

debris that falls on Earth and gets on fire at the entrance in the atmosphere. 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 shooting star often doesn't even get to touch the ground as it

burns completely in the atmosphere. Big-sized meteoroids may not burn completely and they 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 noticeable 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 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. 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 combusted during the

flight through the atmosphere. Past collisions were

devastating for ecosystems, with great flora and fauna damage; should such a shooting star fall in a city,

the effect would be that of a bomb dropping, with

a higher or lower

destructive force depending on the size of the meteor. You can
