Explanation: Stunning emission nebula IC 1396 mixes glowing cosmic gas and dark dust clouds in the high and far off constellation of Cepheus. Energized by the bright, bluish central star seen here, this star forming region sprawls across hundreds of light-years — spanning over three degrees on the sky while nearly 3,000 light-years from planet Earth. Among the intriguing dark shapes within IC 1396, the winding Elephant’s Trunk nebula lies just below center. The gorgeous color view is a composition of digitized black and white photographic plates recorded through red and blue astronomical filters. The plates were taken using the Samuel Oschin Telescope, a wide-field survey instrument at Palomar Observatory, between 1989 and 1993.

Daily Cosmic Calendar for Aug. 4

If your emotional nature appears to be unsettled this morning, join the club. Millions of your fellow terra-firma dwellers are still recovering from yesterday’s Mars-Saturn and Mercury-Neptune clashes. Keep in mind that solar and planetary alignments on one day don’t just disappear 24 hours later. They may lessen in intensity, but they still have an ability to pull the rug out from under you if you are not careful.  Adding to a potential psychic storminess right now is Venus making a contra-parallel link to distant Pluto (8:59AM PDT). Being jealous, moody or temperamental won’t win rave reviews.  On the other hand, antique hunters and collectible aficionados can have a field day in locating nautical-oriented fine-art, books and treasures from the ocean depths under watery Pisces Moon. Immerse yourself in film or literary classics later on. Try out a new recipe for chowder or a favorite seafood dish.  Love vibrations are more upsetting than nurturing this evening as Juno makes a frictional, 45-degree tie with Pluto (9:21PM PDT). Improvise with a musical instrument or dance the night away to relieve yourself of internal pressures.
