Question

Quizplus · Accepted Answer

Sweeping the sky and pointed observations are complementary strategies used in the search for interstellar signals. Sweeping the sky involves searching a wide area in the sky for any signals, whereas pointed observations target specific stars or regions known to have a higher likelihood of harboring extraterrestrial life. The combination of both strategies increases the chances of detecting any signals, as it covers both a broad range of possibilities and potential target areas.
