這些恐龍正在緊張地望著每年一度的英仙座流星雨,照片拍攝于中國內(nèi)蒙古自治區(qū)二連浩特恐龍博物館。以恐龍城著稱的二連浩特在20世紀20年代因發(fā)現(xiàn)恐龍化石而受到關(guān)注。據(jù)信，在大約7000萬年前的白堊紀時期，有20多種恐龍生活在這一地區(qū)。英仙座流星雨是一年中最明亮的流星雨之一，每年7月17日至8月24日之間出現(xiàn)。今年的流星燈光秀將在8月12日晚達到高潮。和大多數(shù)可預(yù)測的流星雨一樣，它發(fā)生在地球軌道與數(shù)百萬顆圍繞太陽運行的彗星之一的長橢圓軌道相交的時候(在本例中為斯威夫特-塔特爾彗星)。它被稱為英仙座流星雨，因為大部分流星似乎來自英仙座。

These dinosaurs are (nervously?) looking at the annual Perseid meteor shower, photographed at the Dinosaur Museum of Erenhot in the Inner Mongolia Autonomous Region of China. Known as Dinosaur City, Erenhot gained attention in the 1920s when dino fossils were found there. It's believed that more than 20 kinds of dinosaurs lived in the area during the Cretaceous Period around 70 million years ago.One of the brighter meteor showers of the year, the Perseids occur every year between July 17 and August 24. This year, the light show will peak on the night of August 12. Like most predictable meteor showers, it occurs when Earth's orbit intersects with the long elliptical path of one of the millions of comets that orbit the sun (in this case, Comet Swift-Tuttle). It's called the Perseid meteor shower because the bulk of the meteors will appear to originate out of the constellation Perseus.
