Aurora Borealis

Aurora is a natural display of light in the sky that can be seen with the unaided eye only at night. An auroral display in the Northern Hemisphere is called the aurora borealis, or the northern lights. A similar phenomenon in the Southern Hemisphere is called the aurora australis. Auroras are the most visible effect of the sun's activity on the earth's atmosphere.

Most auroras occur in far northern and southern regions. They appear chiefly as arcs, clouds, and streaks. Some move, brighten, or flicker suddenly. The most common color in an aurora is green. But displays that occur extremely high in the sky may be red or purple. Most auroras occur about 60 to 620 miles (97 to 1,000 kilometers) above the earth. Some extend lengthwise across the sky for thousands of miles or kilometers.

Auroral displays are associated with the solar wind, a continuous flow of electrically charged particles from the sun. When these particles reach the earth's magnetic field, some get trapped. Many of these particles travel toward the earth's magnetic poles. When the charged particles strike atoms and molecules in the atmosphere, energy is released. Some of this energy appears in the form of auroras.

Auroras occur most frequently during the most intense phase of the 11-year sunspot cycle. During this phase, dark patches on the sun's surface, called sunspots, increase in number. Violent eruptions on the sun's surface, known as solar flares, are associated with sunspots. Electrons and protons released by solar flares add to the number of solar particles that interact with the earth's atmosphere. This increased interaction produces extremely bright auroras. It also results in sharp variations in the earth's magnetic field called magnetic storms. During these storms, auroras may shift from the polar regions toward the equator.

Loch Ness Monster: Real or Hoax?


The existence of the Loch Ness monster has been debated since centuries ago.

In my opinion, there is a great chance that the Loch Ness monster, often nicknamed Nessie does exist in Loch Ness, Scotland. Many attempts to prove it, such as the famous expedition led by Dr. Robert Rines in the year 1972. He and his fellow scientists found recorded evidence using a sonar that something big indeed lives in the great loch. Many sightings by professionals that are unlikely to lie say that Nessie has the form of an aquatic animal much like the extinct plesiosaurus.

Photographs of the monster has also been taken by people trying to find evidence, and many of this photographs has been proved real and not a hoax. But unfortunately, not all of these evidence are authentic. Photographs, videos, even Nessie footprints has been faked. And until now, no one, not even scientists has come up with a carcass or live specimen of this creature. Untill then, we may never be sure that a living creture the so called Loch Ness monster is really living in the loch. I think we should keep a look out for this creature, we might find Nessie as a living dinosaur who survived extinction!

The Legend of Malawen Lake

ONCE upon a time there was a husband and wife who lived near the jungle. They were very poor. They did not have any children yet. Every day they prayed to god to give them a child. One night the wife had a dream. An old man came to her and told her that she and her husband had to meditate for 100 days in the jungle. The wife told her husband about her dream. They hoped it was a sign from god to give them a child.

Later they went to the jungle. After spending for 100 days, they went home. And it was true! Not long after that the wife was pregnant. And nine months later the baby boy was born. The named him Kumbang Banaung.

Kumbang grew as a handsome and strong young man. However he was not obedient. He never listened to his parents' advice. And it happened again when he wanted to hunt in the jungle. It was already dark and his parents asked him to wait until morning. But Kumbang ignored it. He insisted to go to the jungle to hunt.

His parents could not do anything. His father gave Kumbang a magic plate called Malawen. The plate could help him in a difficult situation. After he received the plate, Kumbang went to the jungle.

It was dark and Kumbang could not see clearly. And he had to face the worst risk. He was lost! He kept on walking and finally he crossed the jungle. He arrived in a village. there was a party. Kumbang saw a very beautiful girl. He came to her and introduced himself.

The girl's name was Intan. her father was the head of the village. The party was her birthday party. Kumbang fell in love with her. And after the party was over, everybody went home. Kumbang also wanted to go home. He tried to memorized the way to go home. He was lucky. He could go back home. He arrived in the morning. His parents were so worried. Kumbang did not tell them about his experience. He planned to visit Intan again. And after his parents slept, he left the house.

Kumbang met Intan again. She was happy to see Kumbang. She also loved him. They continued to see each other in the following nights. And it made the villagers restless.

They did not like to see what Kumbang and Intan were doing every night. The villagers told the head of the village to do something. Intan's father had an idea. He came to a rich merchant and asked him to marry his son with Intan. The merchant agreed.

The head of the village told Intan that she would get married soon. Intan was so sad. She told Kumbang to propose her soon. Kumbang immediately told his parents. However they did not agree. They were poor and they thought it was not appropriate for him to propose a rich girl. Kumbang was so angry. He left the house. And he also brought the magic plate.

When he met Intan, Kumbang asked her to run away. And while they were leaving the village, some villagers saw them. They tried to stop the couple. Kumbang and Intan were running. They kept on running and finally they were at the side of a river. They had to cross the river but there was no sampan. Kumbang then remembered about his magic plate. He threw the magic plate to the river.

Amazingly, the plate grew bigger. He asked Intan to get on the plate. They used it as a sampan. While they were crossing the river, suddenly rain fell down heavily. There was a big storm. Heavy wind blew them upside down and finally they were drowning.

Slowly the river changed into a lake. People named the lake as Malawen Lake. People also believed that Kumbang and Intan changed as white crocodiles. They stayed in the lake. Up to now people still believe that the white crocodiles still live in the lake.
