today i learned – mon 20th mar 2017

as it’s the first day of spring today (apparently … i’ll believe it when the rain finally stops πŸ˜’) it’s only right that today’s learning was something spring based!

with that in mind, off i went on my search across the internetweb to find out something interesting about spring … you know what, it was actually a lot more interesting than expected.

anyway, #tdil that the first day of spring is called the ‘vernal equinox’ or ‘spring equinox’ in the northern hemisphere. the vernal equinox marks the moment that the sun crosses the celestial equator (the imaginary line in the sky from north to south).Β 

at this point, the earth’s tilt becomes perpendicular to the sun’s rays and we apparently have exactly 12 hours of daylight and 12 hours of night (equinox even means ‘equal night’ in latin πŸ‘πŸ»)

whilst the first day of spring is known as the ‘spring equinox’ in our fair northern hemisphere, in the southern hemisphere it’s known as the ‘autumnal equinox’ 😎 … it’s feels fairly mad that the equinoxes (there are two every year) are something that the entireΒ world share!

but yeah, that’s about it! this was about as short and sweet as a chinchilla, i still think it’s pretty cool though. who knew that there was more to the first day of spring than just some person deciding that the date should be the 20th march? i certainly didn’t … but than, i’m not all that clever πŸ˜‚

if you’d like to read more (there’s some slightly more technical jargon that what my brain took in) my source of info is –>here<–

buh bye now β˜ƒοΈ #tdil
