Question

question 1
what is the best wavelength to observe young stars being born?
gamma - rays
blue light
infrared
visible
ultraviolet

Explanation:

Young stars are often surrounded by dust clouds. Infrared light can penetrate these dust clouds better than gamma - rays (which are high - energy and not typically emitted in large amounts by young star - forming regions in a way that would be ideal for observation), blue light (which is scattered by dust), visible light (also scattered by dust), and ultraviolet light (absorbed by dust). Infrared wavelengths are less affected by the dust and can reveal the warm regions associated with young stars being born.

Answer:

infrared
