What advantage does data from the James Webb Space Telescope provide in analyzing nebula structure?
Answer
It allows for much better characterization of the warm dust components that trace older, slower ejection events.
The James Webb Space Telescope (JWST) utilizes its capabilities, particularly in capturing infrared light, to enhance the study of planetary nebulae structure. By observing in different light spectra, astronomers can distinguish between layers of ejected material that formed at different epochs. Specifically, JWST data is crucial for characterizing the warmer dust components. This dust traces the material ejected during the earlier, slower wind phase, which forms the outer boundaries of the nebula, helping to reconstruct the full timeline of the star's mass loss history.
