Aliens have landed at Stonehenge! Actually they haven't, and we aren't serious about horoscopes either, but we nearly had you fooled there. Luckily, the rest of our April show has real astronomy in it. We find out some more about gravitational wave detectors and we talk about quasars and black holes. As always we have the news with Megan, get Tim to answer your questions, get a roundup of other podcasts from Stuart and Ian tells us what we can see in the night sky.
