Please read this if you wish to follow APOD during a US Government shut down.
Although the main APOD web page is served from NASA, APOD is written and edited by professional astronomers who do not work for NASA directly as civil service employees. Therefore, APOD will continue to be updated daily even if the US government shuts down, but will (likely) not be served from NASA during this period. To follow APOD during a shutdown, you can link to one APOD's mirror sites found here
Alternatively, you can also find APOD served from the same server that serves the Asterisk, this board. That will be here
Alternatively, you can follow APOD on Facebook here: http://www.facebook.com/AstronomyPictureOfTheDay
