Shooting Stars – A Really Poor Omen Or A Thing Of 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 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 represents a sign 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. 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 through here for more info relating to horoscopes compatibility.
A shooting star is a meteoroid, or some other boulder-sized debris form 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 incredible speed of the meteoroid cause the resemblance with a star. 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 ground causing crater formations. 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 on the dark night sky only, meteoroids and meteors have been reported 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 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.

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 can often cause great damage on Earth’s surface if it is not totally combusted during the passage 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.
