Why do astronomers utilize infrared telescopes and radio observations to study the structure of the Milky Way?
Answer
To penetrate through dense dust clouds that block visible light
Visible light is easily scattered or blocked by the dense dust clouds that permeate the Milky Way. To overcome this, astronomers use infrared telescopes and radio observations. Radio signals, specifically those emitted by ionized hydrogen, can pass through these dust clouds, allowing researchers to pinpoint the locations of star-forming regions that would otherwise remain hidden from view.
