Final answer:
Astronomers use radio telescopes, special infrared telescopes, and space telescopes to observe stars near the Sun. A solar eclipse also provides a temporary means to see such stars with visible light.
Step-by-step explanation:
Astronomers can observe stars near the Sun during the day with the help of specialized equipment such as radio telescopes which are not as affected by the Sun's brightness at certain wavelengths. Observations in invisible light from the ground are hindered by the Earth's atmosphere, but radio telescopes can detect different forms of electromagnetic radiation that penetrate through atmospheric layers even during the day. Thus, the correct answer would be B) Using infrared telescopes, however, option A) Only during a solar eclipse is also a means by which astronomers can observe stars in close proximity to the Sun. This is because solar eclipses temporarily block out the Sun’s light, allowing for visible observation of stars. This capability also hints at the benefits of the placement of telescopes in space to avoid atmospheric distortion entirely, although such missions can be costly and complicated.
