Radio Signals Detected Coming From Distant Galaxy, What Does It Mean?

I saw this story this morning and Lauren and I quickly latched onto it during The Breakfast Club. There have been mysterious radio waves coming from a galaxy 1.5 billion light years away. Some of those signals actually repeated themselves, which makes it more mysterious.

According to the BBC's story, there could be multiple explanations. Could it be alien life, or an alien spaceship? Or is it just some space phenomenon creating this? Scientists are working on an answer and looking for more of these waves, but it is definitely something to keep an eye on.
