Nashville Four Planet Skyline

So far this February, evening skies [ http://antwrp.gsfc.…] have been blessed with a glorious Moon and three bright planets; Venus [ http://www.library.…longfe10.html ], Jupiter, and Saturn. But just last week, on January 30th, an extreme wide-angle lens allowed astrophotographer Larry Koehn to capture this twilight view of Moon and four planets above [ http://www.seds.org…see.html ] Nashville, Tennessee, USA. These major solar system [ http://space.jpl.na…] bodies lie along the ecliptic plane [ http://antwrp.gsfc.…] and so follow a diagonal line through the picture. Starting near the upper left corner is bright Jupiter [ http://starchild.gs…solar_system_level2/ jupiter.html ], which takes on a slightly triangular shape due to the lens distortion. Just below and right of Jupiter is Saturn [ http://www.jpl.nasa…saturn_in_sky.html ]. Continuing along the diagonal toward the lower right is an overexposed, six day old Moon [ http://www.inconsta…] and brilliant Venus seemingly embedded in clouds. The fourth planet pictured is Mercury. Notoriously hard to see from planet Earth because it never wanders far from the Sun, Mercury is [ http://antwrp.gsfc.…] visible just above the lower right corner. The line from Jupiter to Mercury spans about 92 degrees across the Nashville sky.
