It's just an interest. I often have http://astronomy.fm/ on my PC and when I either go to bed early or cannot sleep I listen to it on my internet radio.
I just regard this interest as an ordinary extension of the basic need to know about my town, county, region, country, planet, galaxy, universe etc.
Without being confident at all that I would get a reply I began to ask questions by email to a top physicist (& expert in several other sciences) and a couple of the senior astronomers at SETI (Mountain View / Hat Creek in the USA). I do not trouble these people more than maybe twice a month. They do answer questions. Hat Creek is where the radio telescopes are located, necessarily in a high and quiet area out of the way with no radio traffic that could badly effect these radio telescopes. Mountain View is 300 miles away where the astronomers control the radio telescopes. They only go to Hat Creek for publicity purposes and to make documentaries. The radio telescopes make for more interesting viewing than the office at Mountain View. This office is in Silicon Valley and SETI folk often go down the road to Microsoft to give public lectures which are put onto the internet. Microsoft have good lecture theatre facilities.
Paul Allen (deceased joint founder of Microsoft) in 2009 paid for the radio telescopes and the necessary computer hardware and software at Hat Creek, a cost of 25 million dollars. There are 42 small radio telescopes which the software can make into one big telescope. But they can also be split into a maximum of 4 groups so that each group can be pointed in a different direction. Each group can be any number of telescopes such that the total number does not exceed 42, i.e 6, 10, 7 and 19.
That's strange,I put a post on here about Red Dwarf and now I'm getting news updates about Naylor taking Grant to court over the programme,coincidence?
Also I've been hit by those f@#king adverts again that block my whole screen,for some reason I haven't seen them for the past couple of months and now they are back with a vengeance
