Perhaps also worth noting - if you're nowhere near the (explored) system, you can look at the system map and if it has at least one station/outpost and a planet with metallic rings (analysis of the rings appears on the left of the system view when you select the planet), it's a fair bet there's a RES in them thar rings...
