you are here

I just downloaded Where Is M13? from thinkastronomy.com.

Very interesting program. Answers question I had 30 years ago: where are we, in space, in the galaxy? But I wanted to know this in three dimensions!

I remember, at the time, trying to map this. On paper. On 2-D media. I even tried to carry it further, out to the galactic level. I'll have to track down my maps and maybe scan. Tim Ferris's book, Galaxies, was insightful.

Anyway, this is a fun little program. Nice to see it's available for all platforms.

Hey, look at that. A barred spiral!
