How do instruments like the James Webb Space Telescope (JWST) aid in studying "red monsters" whose redness is caused by obscuration?
Answer
By observing in infrared light, which penetrates the dust shroud more easily.
JWST is crucial because its sensitivity to longer infrared wavelengths allows it to pierce through the dusty cocoons that hide intense star formation, revealing that some supposedly old galaxies are actively forming young stars.
