If it was aliens with some sort of FTL then we should be seeing millions if not billions across the entire universe even our own galaxy but we arent and its probably not some sort of giant radio either as radio is far to slow to be useful over anything except for in system communication so if any such advanced civilizations exist they will either have something that clearly that doesnt travel at the speed of current radio or they would have to rely on courier ships for communication if they lack such ftl communication.
No, what its probably going to turn out to be is some semi rare star or something to do with a blackhole if not both.
