Shooting Stars – Very Beautiful Or Merely Plain Unfortunate?

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 is both varied and suggestive. Thus, westerners commonly make a wish when they

see a falling star, while in other parts of the globe, any shooting

star represents a sign that someone has passed away. 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 over here for more

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 incredible speed of the meteoroid cause the resemblance

with a star. 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.

The light specter as well as the trajectory of the shooting star allow scientists to speculate

on the structure or chemical composition of the falling body. Though noticeable with the naked eye

on the dark night sky only, meteoroids and meteors also fall during

the day, but this time they are detected only by radio signals, with the sunlight making them very difficult to spot

otherwise. Thus, scientists have

concluded that the weight and structure of a shooting star can vary

a lot from snowball lightness to metal heaviness. A very unusual phenomenon is that of a shooting star that passes through just a sector of the

atmosphere without burning completely before resuming its journey in outer space. You

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 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

passage through the atmosphere. Past collisions were

devastating for ecosystems, with vegetation and animal

losses; 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
