It may sound cliche, but the question ‘Are we alone?’ is still one that captures the imagination of many people, including of course, scientists. With the now regular discovery of exoplanets orbiting other stars, the prospect that there may be other intelligent life out there somewhere (or any kind of life) has only become more exciting and compelling. When it comes to intelligent extraterrestrials, SETI is a name that has become part of our modern culture, the Search for Extra-Terrestrial Intelligence. SETI focuses on looking for radio and optical signals that could originate from an advanced society, a technique that in itself has generated much debate. After several decades of searching, a definitive signal has yet to be found, but there have been tantalizing possibilities. Unfortunately, none of those have yet panned out as the signal. Now, another interesting radio signal is making the news – could it be the evidence scientists are looking for or is it another dead-end?
