NASA’s Astronomy Picture of the Day has a very nice picture of Comet Machholz crossing the Pleides, or Seven Sisters. Subaru owners might find this group of stars particularly interesting.
I must admit it, I’m pretty empty today. I have a couple of topics that I could talk about in today’s podcast, but they seem of limited interest to anyone but myself. So, I’m throwing the topics out to my listeners and readers:
Is their some topic that you’d like to hear covered by the Brainwagon Radio Podcast? If so, send me an email or leave a comment in this thread (remember, I have moderation on, so it will take a bit for it to appear) and I’ll use this topic to build a podcast! Help me break through my writer’s podcaster’s block.
Today’s Gem is Things to Make, by Archibald Williams. Yes, it’s dated, but c’mon! Where else are you going to find plans for a silhouettograph? Get the PDF, the illustrations are nice, and the plain text version won’t do it justice.
