To improve the resolution of radio telescopes,astronomers ________.
A)group smaller telescopes in arrays,like the very large array in New Mexico
B)make bigger telescopes
C)place the telescope in outer space
D)scan the skies rapidly to detect the direction of the radio signal

Question

Quizplus · Accepted Answer

Grouping smaller telescopes in arrays allows astronomers to achieve a higher resolution than a single large telescope, as the signals from multiple smaller telescopes can be combined to create a larger effective receiver. This technique is used in the Very Large Array in New Mexico, among other radio observatories. Making bigger telescopes or placing them in outer space may increase sensitivity but does not necessarily improve resolution. Scanning the skies rapidly can help detect the direction of a radio signal, but does not inherently improve resolution.
