On the Gregorian calendar, 2017 will soon begin, but to the Chinese it will be 4715, the year of the rooster. According to China&`&s ancient lunar calendar, the new year falls between January 20 and February 20. This year, it begins on January 28. To close the celebration, the great Feast of Lanterns is held on the first full moon of the New Year.

The dragon had been hibernating since the last festival and will go back to sleep for the rest of the year when the parade ends. 2013 Cervelo P5 Cervelo Cycles Every inch of this bike was designed for speed and performance. Developed for trathletes, the P5 is made of materials specially engineered to reduce vibration and increase performance. Engineers tested the P5 in wind tunnels and used state-of-the-art formula 1-level computational fluid dynamics software to create a super fast bike. Museum of Science and industry Collection. Mine Surface Facilities 1. The raw coal is transported to the surface via conveyors to the stockpile, for feeding into the raw coal silos. 2. Then, the coal is fed into the first stage of the crushing/screening and washing plant, where the coal is processed through a series of meshes, gravity cyclones and flotation to create a consistent size and to separate refuse rock. 3. Next, the cleaned and sized coal is sent to the thermal drying plant, where dryers reduce the moisture content, which in turn increases the BTU output of the coal. 4. The final dried coal is sent to the clean coal silos,for loading onto 100 ton coal cars. The coal is then sent directly onto it&`&s final destination, such as a power plant or a steed mill. Eye Spy: Once upon a time A long time ago in lands far and near Are wondrous stories we all love to hear A princess, a cat and old mother goose A girl who was so frightened she&`&s still on the loose Tales come to life, see petite Cinderella A ring, gift of love, from a much larger fella Stories of romance, heroes and laughter Find the same end: happy, ever after.

The screen fades to black, the talent&`&s unequalled Filming begins next week on the sequel. Eye Spy: Presto-Chango Now what have we here in our strange science lab? Some things that are changing from plain, dull and drab. Our doctor is shedding his morning white coat And sprouting a tail and brown fur at his throat. Do you see a big snake that is shedding his skin? Or a worm in a tank with his colorful skin? Six spiders stand by, all their eyes open wide Making up for three mice who can&`&t see well inside.

Find penguins in bow ties and tuxes and tails And ladies divine, one with a red veil A pink feather boa, a couple about to feast An icicle riding a bicycle on his way home Heading east. VENUS Venus is the hottest planet. Temperatures can reach 900 F On venus, one day is longer than one year Venus&`& atomosphere consists of poisonous carbon dioxide and sulfuric acid. Driving miles from the sun (at 60 mph): 128 years Your weight (if you weigh 100 lbs on earth): 91 lbs Dangers: You would be positioned by the atmosphere, burned by the heat, corroded by the acid, crushed by the weight of the clouds, and have no water to drink. MERCURY Mercury can best be seen from earth just after sunset or just before sunrise. Temperatures range from roughly -300F to 800F Evidence from NASA spacecraft suggests that Mercury has a thick iron core and tons of ice hidden deep in craters. Driving miles from the sun (at 60 mph): 69 years Your weight (if you weigh 100 lbs on earth): 38 lbs Dangers: You would freeze at night, boil during the day, have no air to breathe, no water to drink, and experience intense radiation. EARTH Earth is the densest major body in the Solar System. Earth is about 4.5 billion years old. Right now, Earth is racing around the Sound at 67,000 mph. Driving miles from the sun (at 60 mph): 177 years Life is possible on Earth due to its unique atopheric conditions, the existence of water, and temperate climate. Dangers: Storms, earthquakes, volcanoes, animal predators, diseases, war, pollution, the greenhouse effect and the loss of the ozone layer are among the many dangers. JUPITER Jupiter&`&s Great Red Spot is a hurricane-type storm that has lasted at least 300 years - its diameter is bigger than two Earths. Four of the Jupiter&`&s moons, first observed by Galileo, can be seen with binoculars. It is known as a gas-giant, due to its size and gaseous composition. Driving miles from the sun (at 60 mph): 920 years Your weight (if you weigh 100 lbs on earth): 250 lbs Dangers: There is no water, no air to breathe, and because the planet is composed of gases, not even a surface to stand on. Why are the frog&`&s eyes green? The frog&`&s eyes are green because scientists inserted a jellyfish gene into the frog&`&s DNA. Scientists engineered the gene so that it would work only in the eye. Frequently Asked Questions: How does the chick get out of its shell? The chick has a sharp tooth called an egg tooth, which it uses to crack the sell. The chick pecks its way around the shell until it can get out. How long does it take an egg to hatch? It takes 21 days for a freshly laid egg to develop into a chick. During the 21st day, the chick begins to emerge from the sell. This can take up to ten hours.
