If you were given the chance to use a radio telescope to "listen" for signals from possible extraterrestrial civilizations, which 60-degree "pie wedge" would you choose, and why? How would the two factors that you explored in the previous question influence your choice?

60-degree "pie wedge"

Please elaborate on what a 60-degree "pie wedge" is... I've searched all over Google, and there's no reference that connects "pie wedge" with radio telescopes

What do we mean by a "60-degree pie wedge"?

Notice there are numbers around the outer edge of the galaxy, called Galactic Longitude. One example of a 60-degree pie wedge would be the region from 60 degrees to 120 degrees. (Notice that the difference between 60 and 120 is 60.)  In this artwork, that region is to the left of the Sun, and includes large parts of the Perseus Arm and the Outer Arm.

Thanks for sharing that. I tried doing some research, but couldn't find anything that would be helpful in answering this question. My hypothesis would be to select a wedge that has the highest density of stars. But then again, my knowledge of astronomy isn't strong enough to direct you to where that is, and if it is even possible.

If you end up finding the answer, please share it. This question has sparked my curiosity
