Radio waves are a form of electromagnetic radiation, just like visible light.

I mentioned a few weeks ago that we had joined Google's crowd-sourced question and answer system Aardvark. Now we have an 'Aardvark Group' so that you can send your questions directly to us! Join up at: http://vark.com/g/b657c4 ....

Dan Werthimer, Eric Korpela and I will be heading off to AbSciCon 2010 next week.

Dan's giving a *brand new* talk entitled When will earthlings find ET Should be interesting! Eric's presenting a poster on seti@home data analysis, and I'm presenting a poster describing some of our new SETI instrument architectures.

Want to ask us a question about SETI or astronomy? Try joining our Aardvark network! http://vark.com/s/Bu-l
