I would say our best candidate for a planet with intelligent life. That’s cheating though since we don’t have one (maybe life, but no signs of intelligence yet). The center of the galaxy (outside its black hole) would also be fascinating to pan around what must be a dizzyingly different night sky.

You do have the separate problems of getting any information back home (in a reasonable time at the speed of light) and potentially power (could we ever get a signal from current technology telescopes we place really far away)?
