The northern hemisphere has officially survived a long winter of Arctic temperatures, bomb cyclones, and ice tsunamis. Spring starts March 20, which means warmer weather and longer days are around the corner. To celebrate the spring equinox, hear are some facts about the event.
1. The spring equinox arrives at 5:58 p.m.
The first day of spring is today, but the spring equinox will only be here for a brief time. At 5:58 p.m. Eastern Time, the Sun will be perfectly in line with the equator, which results in both the northern and southern hemispheres receiving equal amounts of sunlight throughout the day. After the vernal equinox has passed, days will start to become shorter for the Southern Hemisphere and longer up north.
2. The Equinox isn't the only time you can balance an egg.
You may have heard the myth that you can balance on egg on its end during the vernal equinox, and you may have even tried the experiment in school. The idea is that the extra gravitational pull from the Sun when it's over the equator helps the egg stand up straight. While it is possible to balance an egg, the trick has nothing to do with the equinox: You can make an egg stand on its end by setting it on a rough surface any day of the year.
3. Not every place gets equal night and day.
The equal night and day split between the northern and southern hemispheres isn't distributed evenly across all parts of the world. Though every region gets approximately 12 hours of sunlight the day of the vernal equinox, some places get a little more (the day is 12 hours and 15 minute in Fairbanks, Alaska), and some get less (it's 12 hours and 6 minutes in Miami).
4. The name means Equal Night.
The word equinox literally translates to equal ("equi") and night ("nox") in Latin. The term vernal means "new and fresh," and comes from the Latin word vernus for "of spring."
5. The 2019 spring equinox coincides with a supermoon.
On March 20, the day the Sun lines up with equator, the Moon will reach the closest point to Earth in its orbit. The Moon will also be full, making it the third supermoon of 2019. A full moon last coincided with the first day of spring on March 20, 1981, and it the two events won't occur within 24 hours of each other again until 2030.
