10^-5 Hz! And I thought I was working at low frequency with my terahertz. I remember working in decametric in the past, but I've never been lower. These frequencies are inverse of orbital periods, aren't they? No way that's the frequency of the photons themselves.
Downside: A life in astrophysics means your life consists of weird numbers and little graphs on screens.
Upside: If you know enough astrophysics to read them, little graphs can be REALLY EXCITING.
