(also Edmund Halley)
- (1656-1742) an English astronomer (= scientist who studies the stars, planets, etc.) and mathematician who was a close friend of Isaac Newton. He is best remembered for Halley's comet, which was named after him. A comet is a bright object that moves through space round the sun with a tail of burning gas and dust. Halley correctly predicted that this one would return regularly to be seen in the night sky approximately every 76 years. It was last visible in 1986.
埃德蒙·哈雷（Edmond Halley）：（1656-1742）是一位英国天文学家（研究恒星，行星等的科学家）和数学家，曾与牛顿的密友。哈雷的彗星以他的名字命名。彗星是一个明亮的物体，它带着燃烧的气体和灰尘的尾巴在太阳周围移动。哈雷正确地预言，大约每76年，这颗星就会定期返回夜空中观看。它最后一次出现是在1986年。
