The Radio Sky
For those of you who don't know me that well, I'm not just about the politics. Yes much of my formal university training is in political science and education, but I also have university level training in astrophysics, physics and chemistry. Why do I bring this up? Well, one of my many hobbies is astronomy (one of my other hobbies, model railroading has it's own page here). Specifically radio astronomy. As part of what I do in this hobby I use a radio telescope to scan the heavens. A preliminary result of some of this work is the picture below. It represents the various sky brightnesses at a frequency of 800 MHz. From least bright to most bright the colours are black, blue, turquoise, pink, purple, red, orange then yellow. The light blue outline that forms a “U” on the map is the visible Milky Way. It is clear that there's more to the sky than meets the eye.
