[DC] When Superman looks up at the night sky from Earth, can he see any Alien Civilizations? Is his super-vision that powerful? Similarly, are there any advanced alien civilizations/cultures/planets within range of his super-hearing when he's on Earth?

Basically, what could Superman tell humanity about the Universe if he decided to use his super-senses (and ONLY his super-senses; no actual flying to Space or anything like that) to become an Astronomer?

Hes not that powerful. He can't see through all the distortion from atmosphere and solar radiation to spot individual cities on planets far away. He can probably tell a little more than a telescope can but it's still a blur with some odd light refraction at best. Could be ice on the planet or could be satellites in orbit. As for his hearing he can only hear in atmosphere. In space there's nothing for sound to travel through so he can't hear anything in the void or from beyond it.
