This has been posted several times already. It's sensationalist. Before anyone gets too excited, be aware that Jupiter (as one example) emits radio waves [1].
I don't think the researchers are necessarily suggesting an alien origin (honestly, shame on them if they are). It's more likely sensationalist reporting. It's almost certainly natural in origin.
