This guide breaks down its literal meaning (“great emptiness”), cultural significance in China's modern space ambitions, and practical usage. Discover the crucial difference between 太空 (tàikōng) and 天空 (tiānkōng) (the sky), and explore related vocabulary for space exploration, astronauts, and the universe.

• Pinyin (with tone marks): tàikōng
• Part of Speech: Noun
• HSK Level: HSK 4
• Concise Definition: The physical universe beyond the earth's atmosphere; outer space.
• In a Nutshell: 太空 (tàikōng) is the direct and most common word for what we call “outer space” in English. It refers to the vast, empty expanse that contains stars, planets, and galaxies. Think of it in a scientific context—the place where rockets fly and astronauts conduct missions.

• 太 (tài): This character means “great,” “supreme,” “grand,” or “too.” It implies a scale that is immense and beyond the ordinary.
• 空 (kōng): This character means “empty,” “void,” “hollow,” or “sky.” It points to the vast emptiness and lack of air.
• Together, 太空 (tàikōng) literally translates to the “Great Emptiness” or “Supreme Void.” This is a wonderfully descriptive and almost poetic name for outer space, capturing its immense scale and emptiness in just two characters.

Historically, Chinese culture has been deeply connected to the heavens, but the focus was on 天空 (tiānkōng), the sky visible from Earth. Ancient astronomy was tied to philosophy, agriculture, and the Emperor's “Mandate of Heaven” (天命, tiānmìng), where celestial events were seen as signs for earthly affairs. The modern term 太空 (tàikōng), however, represents a shift from philosophical observation to scientific exploration. In contemporary China, 太空 is a powerful symbol of national pride, technological prowess, and future ambition. The success of the Chinese National Space Administration (CNSA)—with its lunar rovers, Mars missions, and the Tiangong space station (天宫空间站)—is a frequent source of positive news and a testament to the nation's rapid development. Compared to the American cultural view of space as the “final frontier,” often imbued with a spirit of individualism and discovery (think *Star Trek*), the Chinese perspective on 太空 is more often framed through the lens of national achievement and collective effort. It represents China's arrival as a major player on the world stage, a journey “to the sea of stars” (征途是星辰大海) undertaken by the nation as a whole.

太空 is used in a variety of modern contexts, almost always with a neutral or positive connotation related to science and progress.

• Science and Education: It is the standard technical term used in astronomy, physics, and any discussion about the cosmos.
• News and Media: You will constantly hear 太空 in news reports about rocket launches, satellite deployments, and updates from the Chinese space station.
• Science Fiction (科幻, kēhuàn): It is the default term for the setting of sci-fi movies, books, and games that take place beyond Earth.
• General Conversation: When talking about dreams of becoming an astronaut or the possibility of alien life, 太空 is the word you would use. It is a formal term, but universally understood by everyone.

  • English: My dream is to become an astronaut and travel to space.
  • Analysis: This sentence shows a personal aspiration. Note that 宇航员 (yǔhángyuán) is a general term for astronaut, while 航天员 (hángtiānyuán) is specifically used for Chinese astronauts.

The most common mistake for learners is confusing 太空 (tàikōng) with 天空 (tiānkōng).

• 太空 (tàikōng): Outer space. The vacuum, the cosmos, where planets and stars are. It is black.
• 天空 (tiānkōng): The sky. The Earth's atmosphere, where clouds and birds are. It is blue during the day.

Think of it this way: A rocket flies through the 天空 (tiānkōng) to get to 太空 (tàikōng).

• 错误 (Incorrect): 天气很好，太空是蓝色的。 (Tiānqì hěn hǎo, tàikōng shì lán sè de.)
  • Why it's wrong: This sentence says “The weather is good, outer space is blue.” Outer space is not blue. You are talking about the sky you see from Earth.
• 正确 (Correct): 天气很好，天空是蓝色的。 (Tiānqì hěn hǎo, tiānkōng shì lán sè de.)
  • Translation: “The weather is good, the sky is blue.”

Another point of nuance is the difference with 宇宙 (yǔzhòu):

• 太空 (tàikōng): Refers to the physical location/region of outer space.
• 宇宙 (yǔzhòu): Refers to the entire universe as a concept, including all of space, time, matter, and energy. It's a much broader, more philosophical, and scientific term.

You travel *in* 太空, but you study the origin of the 宇宙.

• 天空 (tiānkōng) - The sky; the atmosphere above the Earth. The most critical term to distinguish from 太空.
• 宇宙 (yǔzhòu) - The universe; the cosmos. The all-encompassing concept that contains 太空.
• 航天员 (hángtiānyuán) - Astronaut. This is the official term for a Chinese astronaut. (宇航员, yǔhángyuán, is more general).
• 空间站 (kōngjiānzhàn) - Space station. A structure orbiting Earth where astronauts live and work.
• 火箭 (huǒjiàn) - Rocket (lit. “fire arrow”). The vehicle used to travel to space.
• 行星 (xíngxīng) - Planet (lit. “wandering star”).
• 外星人 (wàixīngrén) - Alien; extraterrestrial (lit. “outer-star-person”).
• 探索 (tànsuǒ) - To explore; exploration. A verb often paired with 太空.
• 航天 (hángtiān) - Spaceflight; aerospace. The general field or industry.
• 飞船 (fēichuán) - Spaceship; spacecraft (lit. “flying ship”).
