[Homework]【整理】2012-05-07&05-09 “超级月亮”背后的科学

Homework: It was last night right around here ______ the super moon. Well, tonight, if you lucky have the clear sky, you will have quite shown, but we want to know the science behind why it would seem bigger and brighter that we've seen in years. Who can forget that famous flight 80 in silhouette. Watch barely after the moon is a wonderful life. Just see the world now toward pull down. And of course, there was share said we've all silent one point. I never seen a moon like that before. And if you look at bit little sky tonight chances are you will be star struck again or should we say moonstruck the super moon, the biggest and brightest full moon of this year. It turns out not all full moons are created equal orbit around the earth  Isn't a perfect circle, is a ellipse.  And tonight's moon known as a perigee full moon, will be closed to us at the exact moment. When it becomes full 221000 miles away, at 17000 miles closer than the typicle full moon. And it's the proximity that will give us a few 13% brighter, 14% bigger. Bigger than everything is illuminated. Look at these images from the last super moon. People like specks on the harizon that playing imaging being on that fight. And it turns out there's more to the science of the super moon. In fact, ocean tides will be more extreme this weekend, but about those stories of full moons bring out bizarre behavior. Come on, come on…It's all a mean severe researcher. And one more spectacle in the sky to look for those tiny specks capured byNASA telescopes. Here, those are fireballs, a meteor shower, all pieces of debris from hades, comet this year. The people tonight into tomorrow sign to say about 40 to 60 meters per hour, all of them perhaps a little more difficult to spot.
