Solution

Solution Steps

Step 1: Understand the Question

The question asks which of the given options is NOT part of the "cosmic haystack problem" in receiving messages from other civilizations in space. The "cosmic haystack problem" refers to the challenges and uncertainties involved in searching for extraterrestrial signals.

Step 2: Analyze Each Option

We don't know what star might have planets with intelligent life: This is a part of the cosmic haystack problem because identifying which stars to focus on is a significant challenge.
We don't know whether the signal is always on (continuous) or only for a brief time every cycle: This is also part of the problem because the nature of the signal's transmission affects our ability to detect it.
We don't know what channel they may be using to send messages: This is another aspect of the problem, as the frequency or channel used for communication is unknown.
We don't know how to receive signals in the wavelength range that is the most likely for interstellar communications: This is not part of the cosmic haystack problem. Astronomers have the technology to receive signals across a wide range of wavelengths.
We don't know how other civilizations might encode messages in the carrier wave they send: This is part of the problem because the encoding method used by extraterrestrial civilizations is unknown.

Step 3: Identify the Correct Answer

Based on the analysis, the option that is NOT part of the cosmic haystack problem is the one related to the ability to receive signals in the most likely wavelength range.
