Astronomy is one of the most exciting science because many celestial phenomena that are simply awesome and beautiful to see. Not only that, the whole universe is a mystery that can never be fully explained by science. There are new discoveries, as the existence of distant galaxies and black holes that are constantly being revealed by the space exploration programs. The reason why we are so fascinated these celestial objects is because many of them pose a threat to our human existence. Whatever cataclysm that occurs may lead to further the destruction of our planet.
More of these strange events are happening in very large distances from Earth and are too far from causing a disaster. However, there are some that are relatively near us. Among these are the asteroids that are large rocks with a diameter up to miles. These celestial objects have become the talk of the town by astronomers, diviners, and the public because of fears that if one of them hits us, the human race will deleted. Scientists are still searching for evidence supporting the theory of dinosaur extinction caused by huge asteroid impacts.
It is very important to separate fact from fiction regarding the asteroids. According to popular culture represented by the books Science fiction and films, one of the craziest ideas is that these spaces objects allegedly used by aliens to dominate the world. Some alien life forms are believed to be found in areas of impact, a strange epidemic spawning and cause havoc humans. However, the concept is the most popular asteroid crashes to Earth and using our latest technology to prevent the disaster said.
To allay our fears, the scientific community is still conducting research on the nature and composition of these celestial bodies. Their studies helped us understand the truth about asteroids. These are actually the debris that can range from a golf ball huge boulders as large as continents. Because they do not distinguish particular orbits of planets and moons, and they can actually hit several times our planet. However, who entered the atmosphere of our Earth are called meteorites and these are generally small. Some are known as meteors, as were completely burnt and have completely turned into dust. The chances of a sudden Direct from a giant asteroid is relatively small, but astronomers do not take this for granted. Using telescopes that are strategically placed in different sites around the world, they continue to look up the signs of asteroids that can enter a collision course with our planet dangerous.
Another fact is that an asteroid belt between Mars and Jupiter. This is where most asteroids come. Astronomers have separated these classes according to their material composition and the proximity of that planets. Those who are closest to Mars belong to Class S, while those closest to Jupiter are known as Classes C, D and V. The classes are called Centaur asteroids and they include materials and compositions are known to drift the vast space of Jupiter to Uranus. For an overview firsthand these celestial monsters, scientists have sent spacecraft to fly near them. The asteroid Ida has been called observed by the Galileo spacecraft from a distance of about 1,000 miles and found that its own moon. Some probes have actually landed on asteroids and amazing photographs sent to us to enjoy.
