| For over 350 years men have used
telescopes to find out more about the stars and planets. Our knowledge of the
stars has increased very greatly since Galileo, the famous Italian scientist,
made the first telescope in 1609. Men have used telescopes to study the moon’s
surface—its craters (环形山), mountains and plains. Now men have recently
built bigger and more powerful telescopes. They have discovered new groups of
stars. Modem telescopes have shown us that certain stars are not single at all;
they are groups of millions of stars. The largest telescope in the world has a mirror which is 200 inches wide. It is at Mount Palomar in America and it has shown us millions of new stars. The light from these stars has taken a million years tO reach the earth. |

{{B}}Find Yourself Packing It On Blame
Friends{{/B}} Obesity can spread from person to person, much like a virus, researchers are reporting today. When one person gains weight, close friends tend to gain weight, too. Their study, published in The New England Journal of Medicine, involved a detailed analysis of a large social network of 12,067 people who had been closely followed for 32 years, from 1971 to 2003. The investigators knew who was friends with whom as well as who was a spouse or sibling or neighbor, and they knew how much each person weighed at various times over three decades. That let them reconstruct what happened over the years as individuals became obese. Did their friends also become obese Did family members Or neighbors The A.
