1) An American-born giant panda will soon be travelling to China. The Chinese government has an agreement with foreign zoos to lend giant pandas out only for scientific study. After a few years, they, and any cubs they may produce, must all be returned to China. Mei Lan, a three-yearold female, is being prepared for her trip to China, where her parents were born. A special FedEx flight from the U.S. is being arranged for her.
2) Chinese Zookeepers are getting ready for her arrival by planning a special diet, and even language lessons for her. They are advertising for a tutor to teach Mei Lan Chinese. The caretakers at her new home, the Chengdu Panda Research Center in Sichuan, want to help her adapt quickly and feel comfortable in her new environment. Mei Lan has lived at a zoo in the city of Atlanta, Georgia, since her birth, and she is unfamiliar with Chinese. The teacher must have a bachelor's degree or higher and be fluent in both English and Chinese.

(1) If we look at the night sky carefully, we will see that the stars are of many different colors. Some are red, others are yellow and some are blue. This is also shown when we take color photographs of the night sky. You can take such a photograph with an ordinary camera as long as it is kept steady. A thirty second exposure is sufficient.
(2) Astronomers have been able to classify stars according to color. They have found that blue stars are the largest and red stars the smallest. However, there are a few stars which cannot be classified in this way. These are the superstars. For example, Ryiejol is a blue superstar as big as 40,000 suns and Beetle juice is a superstar with a size equal to 17,000 suns.
(3) Suppose an astronomer observes two stars, one brighter than the other. If neither of them is a superstar, he will know immediately that the brighter star is closer. Astronomers have instruments like light meters which can measure the brightness of a star quite accurately. It is possible to measure a star's distance from the earth if astronomers know the color, brightness and whether or not it is a superstar.
