英语词汇“astronomer”的英英意思、用法、释义、翻译、读音、例句、短语、词组-英语词典

A scientist who studies the objects in the sky, including planets, galaxies, black holes, and stars, is called an astronomer.

These days, the terms astronomer and astrophysicist are used interchangeably, to talk about any physicist who specializes in celestial bodies and the forces that affect them. Astronomers use telescopes and cameras to observe the stars and other objects in the sky, and they often use complicated math to make predictions and solve puzzles about their movements and locations. The Greek root, astronomia, literally means "star arrangement."
