SPACE, EXPLAINED SIMPLY
How space missions turn questions into measurements.
01
NASA is the United States agency for aeronautics and space research. Its work includes human spaceflight, robotic missions, astronomy, Earth science, aviation, and technology development.
Every mission depends on scientists, engineers, and partner organisations. A launch is only one stage: instruments must be prepared, data transmitted, and results carefully analysed.
02
Webb observes the Universe mainly in infrared light. It is designed to investigate early galaxies, stellar birth, planet formation, and the atmospheres of some exoplanets.
Scientists study spectra as well as images, separating light by wavelength to learn about matter and temperature. Detecting a molecule alone does not prove that life exists.
03
Start any space headline by asking what was actually measured. Check whether it describes an observation, a computer model, or a future plan; words such as “possible” and “candidate” signal that more confirmation is needed.
An official mission page provides purpose and context, while a scientific paper explains method and limits. Checking both is a useful habit for any claim about space.
