All,
Curiouser and curiouser.
Yesterday, the Earth Science Picture of the Day http://epod.usra.edu/blog/2011/11/antli ... vesta.html showed craters on Vesta (and compared them with antlion pits), an extraterrestrial subject, and today, the APOD http://apod.nasa.gov/apod/ap111108.htmlis of sundogs and thunder clouds, a thoroughly earth-bound topic!
But I'm not complaining!
