3.认识夏季星空中的显著星座

Recognize the prominent constellations in the summer sky.

认识银河

Know the galaxy.

在银河东“岸”有一颗亮星,在这颗亮星的两侧各有一颗比较暗的星 ,3颗星构成一个扁担形。这颗亮星叫做“牛郎星”。牛郎星位于天鹰星 。

There is a bright star on the East Bank of Yinhe river. There is a dark star on both sides of the bright star. Three stars form a pole shape. This bright star is called Altair. Altair is on the eagle.

在银河西“岸 ”,与牛郎星隔河相望 ,有一颗特别显眼的亮星 ,在这颗亮星附近还有4颗比较暗的星构成梭子形。这颗亮星叫做“织女星”。织女星位于天琴星座。

On the West Bank of the Milky way, across the river from Altair, there is a bright star which is very conspicuous. Near this bright star, there are four dark stars forming a shuttle shape. This bright star is called Vega. Vega is in the constellation lyre.

我国家喻户晓的牛郎织女的故事 就是根据这两颗亮星想象出来的

The story of Cowherd and weaver girl, which is well-known in our country, is based on these two bright stars.

认识天蝎座。

Meet Scorpio.

天蝎座是夏季南天最显眼的星 ,里面亮星云集 ,可以说是夏夜星座的代表

Scorpio is the most prominent star in the southern sky in summer, with bright stars in it, which can be said to be the representative of the summer night constellation

天蝎座中有一颗红色亮 星,犹如天蝎的心脏,他就是著名的心宿二 ,也叫“大火星 ”,还被称为“商星”。在夏天晚上八九点钟的时候 ,它位于南方离地平线不很远的地方 。因为这时候南边低空中多是些暗星,所以它非常显眼。找到了这颗星,天蝎座的其他部分就不难辨认出来了。

There is a bright red star in Scorpio, just like the heart of Scorpio. He is the famous Antares, also known as "Mars", also known as "quotient star". At eight or nine o'clock in the evening in summer, it is not far from the horizon in the south. Because there are many dark stars in the southern low sky at this time, it is very conspicuous. Once this star is found, the rest of Scorpio will not be difficult to recognize.

4.整理我们近一年来对星空的观察。

Sort out our observations of the starry sky in the past year.

画出四季中的北斗七星。

     去年秋末西沉的星座到今年秋天又回来了 ,到秋末会再西沉。

The constellations that sank westward at the end of last autumn will come back this autumn, and they will sink westward again at the end of autumn.

提出要研究的新问题
