_Today, the Sun_ (http://sunearthday.nasa.gov/2009/index.php) crosses the celestial equator heading north at 11:44 _UT_ (http://aa.usno.navy.mil/faq/docs/UT.php) . Known as an equinox, this _astronomical event_ (http://www.phy6.org/stargaze/Sseason.htm) marks the first day of spring in the northern hemisphere and autumn in the south. It also marks the beginning _of Norouz_ (http://en.wikipedia.org/wiki/Norouz) , the Persian (Iranian) new year. Equinox means _equal night_ (http://hyperphysics.phy-astr.gsu.edu/Hbase/eclip.html#c5) . With the Sun on the celestial equator, _Earth dwellers_ (http://apod.nasa.gov/apod/ap030923.html) will experience _nearly_ (http://aa.usno.navy.mil/faq/docs/equinoxes.php) 12 hours of daylight and 12 hours of darkness. Of course, in the north the days will grow longer, the _Sun marching_ (http://apod.nasa.gov/apod/ap040320.html) higher in the sky as summer approaches. To celebrate the equinox, consider _this scenic view_ (http://www.perseus.gr/Astro-Solar-Scenes-Portara-03.htm) of the setting Sun from the island of Naxos in the Aegean Sea. Recorded last June, the well-planned image captures the Portara (big door) in a dramatic silhouette. Measuring about 6 by 3.5 meters, the Portara is the large entrance to the Greek island's ancient, unfinished Temple _of Apollo_ (http://www.pantheon.org/articles/a/apollo.html) . **************Feeling the pinch at the grocery store?
