Understanding 星系 (xīngxì)
The word 星系 refers to a galaxy, a massive system of stars, stellar remnants, interstellar gas, dust, and dark matter bound together by gravity. It is a scientific term used primarily in astronomy.
Usage in Context
You will often see 星系 used in discussions about space, astronomy, and cosmology. For example, the Milky Way is called 银河系, literally 'Silver River Galaxy,' which is a specific 星系.
Common Collocations
- 银河系 (Yínhéxì): The Milky Way galaxy, the galaxy that contains our solar system.
- 星系之间 (xīngxì zhījiān): Between galaxies, used when discussing distances or relationships among galaxies.
- 星系结构 (xīngxì jiégòu): Galaxy structure, referring to the composition and arrangement of a galaxy.
Notes
星系 is a formal, scientific term and is not used in casual conversation unless the topic is astronomy or science. It is often paired with other scientific vocabulary. Avoid confusing 星系 with 星星 (xīngxing), which means 'star' in a more general or poetic sense.
When using 星系, the context usually involves large-scale space phenomena rather than individual stars or planets.
