What is the main reason for positioning many radio telescopes across a large area and combining the signals?
A)to provide a backup system if one or more of the telescopes go down
B)to produce higher resolution images
C)to prevent interference between signals from the separate telescopes
D)to compensate for the motion of objects in the sky as a result of the Earth's rotation

Question

Quizplus · Accepted Answer

Positioning many radio telescopes across a large area and combining the signals can produce higher resolution images, allowing for more detailed observations and analysis. This is known as interferometry, and it allows for a larger effective "aperture" than any individual telescope, leading to increased resolving power.
