存最古老的观测记录可能已有3500年的历史 。古代中国人把这些信息雕刻在动物的骨头 之上。学者们认为，这指的是大约3500年前 的天文观测。 • 在世界上，最古老的现存建筑之一,埃及金字 塔，建筑于4500年前。这似乎把天空中的一 个或多个明亮的星星的位置与之排成一行。 大约500年以后，英国的巨石阵一直被用来指 示夏至日出的位置。
The most elaborate of ancient observatories was built in Persia some 600 years ago by Ulugh Begh, but we do not know what it looked like.

The History of Space Observation and Travel
Para1. When were the first astronomical observations made? Para2. When were the first observation build? Para3. When was Halley’s Comet first seen? Para4. When were the first telescopes used? Para5. When was the fist artificial satellite launched? Para6. When did the first spacecraft land on another world?
One of the oldest surviving structures in the world, the Great Pyramid in Egypt, was built about 4,500 years ago.

About 500 years later, Stonehenge in England could have been used to indicate the midsummer sunrise position.

Para2. When were the first observation build?
The first “observatories” were built long before telescopes were invented. A structure in Korea, dating from about AD640, may have been an observatory. A building put up by the Toltec people of Mexico around the 13th century AD may also have been an observatory.
