Shooting Stars - A Really Terrible Omen Or A Thing Of Great Beauty
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 implies diverse meanings associated
with old beliefs sometimes. 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. 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 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 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 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 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 very bright shooting star 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
passage through the atmosphere. Past collisions proved
devastating for ecosystems, with vegetation and animal
losses; if such a shooting star fell in a city,
the effect would be that of a bomb attack, with
a higher or lower
destructive force depending on the size of the meteor. You can
