Radio Signals From Space Explained?

We've been getting regular radio signals from space that have scientists perplexed for a while now, many of which seem to generate from the same location, over and over again. Those of us who are dying to make contact with life on another planet are obviously hoping for some intelligence behind the signals, but now scientists believe that the signals may actually be from a wobbling star!

The waves may come from high energy beams from the star, which would explain why they've been coming from the same place all this time. But would they be so regular as well? How many of us are actually picturing some being working on a distant version of Morse Code here?

What do you think the mysterious signals are coming from?
