    Explanation: Yesterday was an equinox, a date when day and night are equal. Today, and every day until the next equinox, the night will be longer than the day in Earth's northern hemisphere, and the day will be longer than the night in Earth's southern hemisphere. An equinox occurs midway between the two solstices, when the days and nights are the least equal. The picture is a composite of hourly images taken of the Sun above Bursa, Turkey on key days from solstice to equinox to solstice. The bottom Sun band was taken during the winter solstice in 2007 December,...

    Explanation: September's equinox arrives tomorrow as the Sun crosses the celestial equator heading south. The event marks the astronomical beginning of spring in the southern hemisphere and autumn in the north. And though the connection is still puzzling, the equinox seasons bring an increase in geomagnetic storms. So as northern nights grow longer, the equinox also heralds the arrival of a good season for aurora hunters. Recorded on September 20, these colorful northern lights were captured with camera and wide-angle lens near the Norwegian Sea coast outside Tromsø in Northern Norway. Shining at altitudes of 100 kilometers or so, the...

    Parthenon MoonExplanation: Did you see the Full Moon last night? Near the horizon, the lunar orb may have seemed to loom large, swollen in appearance by the famous Moon illusion. But the Full Moon really was a large Full Moon last night, reaching its exact full phase within an hour of lunar perigee, the point in the Moon's elliptical orbit closest to planet Earth. A similar near perigee Full Moon last occured on December 12, 2008. The difference in the Moon's apparent size as it moves from perigee to apogee, its farthest point from Earth, is about 14 percent. Of...

    No, I'm not obsessed with Saturn. OK, I am obsessed with Saturn. But so is Time, who picked this deliciously crispy photo as one of the images of the year, revealing ring bumps as high as the Rocky Mountains. I'm not surprised, because it's a truly unique moment, one that happens at Saturn's equinox, which is an event that only happens twice in 10,179 Earth days. And this time, we had Cassini there to take this amazing photo, just when the sun illuminates the rings edge-on. As Carolyn Porco—Cassini imaging team leader—puts it: The geometry revealed structures and phenomena in...

    http://www.nasa.gov/externalflash/cassini_equinox/cassini_equinox_slideshow.html That is a link to a slideshow that NASA is hosting, that has some of them most stunning pictures of Saturn I've ever seen. Saturn was at equinox in August, meaning that the sun was exactly over the edge of the rings. That may not sound like a big deal, but Saturn takes 30 years to make one orbit, so equinox comes every 15 years. The difference this time is that the Cassini spacecraft was in place to watch it happen first hand, and the images are stunning. Think about a sandy beach at high noon. If you look...

  • Druids in the House for Spring Equinox, Saturday in Redwood City

    Examiner ^ | March 20
    Wassup, pagans? Me and the rest of my heathens plan to gather Saturday in Redwood City to celebrate the change of seasons. Well, I might not be there, but the the Druid posse should be in full effect. I don't mean a rival to the now defunct Taliban gang. I mean reconstructed Celtic-religion adherents from the Fellowship of Druidism for the Latter Age. I got the word as a member of the San Jose Pagan/Magick Meetup Group, although I admit I've yet to attend a face-to-face event. It's more a matter of motivating the body off the couch than encouraging...

    Cyrus the Great Cylinder, The First Charter of Human Rights By 546 BCE, Cyrus had defeated Croesus, the Lydian king of fabled wealth, and had secured control of the Aegean coast of Asia Minor, Armenia, and the Greek colonies along the Levant. Moving east, he took Parthia (land of the Arsacids, not to be confused with Parsa, which was to the southwest), Chorasmis, and Bactria. He besieged and captured Babylon in 539 and released the Jews who had been held captive there, thus earning his immortalization in the Book of Isaiah. When he died in 529, Cyrus's kingdom extended as...

The answer is no, and the shape traced out by the Sun over the course of a year is called an analemma. The Sun's apparent shift is caused by the Earth's motion around the Sun...
