What's behind the Moon? Each month, our Moon [ http://antwrp.gsfc.nasa.gov/apod/ap010218.html ] passes in front of -- and outshines -- many an interesting star field. Exceptions occur during a new Moon [ http://aa.usno.navy.mil/faq/docs/moon_phases.html ] and during a total eclipse [ http://www.mreclipse.com ]. In the background of a new Moon [ http://www.nineplanets.org/luna.html ] is usually the Sun [ http://www.nineplanets.org/sol.html ], an even brighter orb that even more easily outshines everything behind it, except during a total solar eclipse [ http://antwrp.gsfc.nasa.gov/apod/ap010408.html ]. Even the longest total solar eclipse [ http://antwrp.gsfc.nasa.gov/apod/ap030106.html ] lasts just a few minutes, while the Sun's corona [ http://www-istp.gsfc.nasa.gov/Education/wcorona.html ] still remains bright. During a total lunar eclipse [ http://antwrp.gsfc.nasa.gov/apod/ap030522.html ], however, the full Moon [ http://antwrp.gsfc.nasa.gov/apod/ap000113.html ] dims and a majestic star field may present itself for an hour or more. Such was the case during the middle of last month, when a rare glimpse of an eclipsed Moon superposed in front of the disk of our home Milky Way Galaxy [ http://antwrp.gsfc.nasa.gov/apod/ap990224.html ] was captured. Although fully in the Earth's shadow [ http://www.mreclipse.com/Special/LEprimer.html ], the eclipsed Moon is still the brightest object on the right. The above image was captured during sub-zero weather from the Teide 2003 expedition [ http://www.shelios.com/teide2003/ciencia.htm ] to Mirador del Pico Viejo [ http://www.arrakis.es/~jalopezd/espa/sender_12.htm ], a mountain in the Canary Islands [ http://www.red2000.com/spain/canarias/ ], Spain [ http://www.cia.gov/cia/publications/factbook/geos/sp.html ], off the northwest coast of Africa [ http://www.library.northwestern.edu/africana/map/ ].
