A plethora of constellations
The earliest sunset of the year will be Monday December 7th at approximately 4:35 pm. We will start to see sunsets coming later and later, but the total length of day is still shrinking. The shortest day will just be over 9 hours of light. How about the age old chicken and egg question. What comes first, black holes or galaxies? The two actually develop together, feeding off of each other. One scientist has theorized that black holes may spur development of galaxies. Where are these black holes? Also don’t miss a full spread of really great constellations from summer stretching into winter including the Geminid meteor showers. For more information on how to view the Geminid Meteor shower visit hubblesite.org.Listen:[audio: st20091207.mp3]
