The sun is shining at zenith – or overhead – at Earth’s equator today. This is the March equinox, which arrives this afternoon or evening in the U.S. ... and tomorrow for Europe, Africa, Asia, Australia and New Zealand. The March equinox happens at the same moment for all of us, around the world. It’s when the sun crosses the celestial equator, moving from south to north. The exact time of this equinox is 12:07 a.m. Universal Time tomorrow. But the time on your clock will vary according to your time zone. On the day of an equinox, the sun rises due east and sets due west all around the world. Everyone receives approximately 12 hours of daylight and 12 hours of night. For the coming six months following the March equinox, the sun will rise and set north of due east and west, bringing longer days to the northern hemisphere. Meanwhile, in the southern hemisphere, the days will be growing shorter. Winter will be on its way. The position of the March equinox sun relative to the stars is called the first point in Aries. But nowadays, the sun resides in front of the constellation Pisces on the March equinox. This evening, notice the waxing crescent moon and brilliant planet Venus in the west. Venus shows you where the March equinox sun once stood in front of Aries over 2,000 years ago. |
