The 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 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 through here for additional

A shooting star is a meteoroid, or some other boulder-sized debris form 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.

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

only at night, 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

determined 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 very bright shooting star 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 can often cause great damage on Earth’s surface if it is not totally burned during the

flight through the atmosphere. Past collisions were

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

the effect would be that of a bomb attack, with

the intensity of the explosion varying according to the size of the meteorite. You will
