Question

Quizplus · Accepted Answer

Infrared telescopes are used to observe protostars because they can detect the temperature and the presence of dust. Protostars are surrounded by dense clouds of dust and gas, which absorb visible light, making it difficult for traditional telescopes to observe them. Infrared telescopes can detect the heat radiated by the protostars and the dust, allowing astronomers to study their formation and evolution.
