What is the MAIN reason for using several radio telescopes together as an interferometer?
A) to obtain much better angular resolution or sharpness in the images
B) to ensure that at least one of the telescopes is in a radio-interference-free zone
C) to collect more radiation from very faint sources
D) to ensure that observations are uninterrupted by the failure of one or two telescopes

Question

Quizplus · Accepted Answer

The main reason for using several radio telescopes together as an interferometer is to obtain much better angular resolution or sharpness in the images. By combining the signals from multiple telescopes, interferometry allows for more precise measurements of the position and properties of cosmic objects.
