For the next week, the twilight sky will feature a close alignment of two bright shiny red objects, Mars and Antares, and the slender Moon wending its way through the southwestern sky. The Moon encounters the ringed planet Saturn on Saturday 27th and then brackets the close pairing of orange-red Mars and the red supergiant star Antares in the constellation Scorpius. This first lunar cycle of autumn should start out beautifully with the waxing Moon and some lovely alignments. Look south and west shortly after sunset each evening for the best viewing.
In 2005 I began writing a column for the San Francisco Waldorf School newsletter called "The Urban Astronomer." I started this blog in 2007 as a place to archive my articles and to offer additional insights on the night sky - even if you live in a big city. In 2008 I became an occasional guest on the KFOG Morning Show, and more recently on KALW and KGO. Archived shows are posted on the blog.
