Looking without our eyes

There is so much out there that we cannot see. Wonders. Phenomena that we can only imagine. And it's all because we have always lived here, surrounded by the light of our sun, struggling to adapt and survive on this planet. Nevertheless, nothing can stop us from imagining how it would be if life was something that was happening in a much broader region of space, instead of being limited by a planet. What if life was struggling to survive on an entire solar system - or even in a galaxy (or in a large portion of the universe? Sure we could come up with a huge amount of arguments that would clearly show that this hypothetic scenario is, at least, non-sense. However, if by some way, life could evolve and become a solar-system, galactic or a universal phenomena, then it would have to adapt "its creatures" to the extremely "weird" environment. Beings which could only see visible light would definitely be eliminated rapidly (unless they somehow could come up with a smart "external" solution, like human beings). Thus, multi-wavelength vision would be highly important, not only to search for points of interest, but also to probe some of the biggest dangerous along the galaxy. What other changes would have to take place? Will they ever happen?
