Axial tilt is the reason for the season!


Happy Winter Solstice, which will occur at 15:03 UTC (10:03 a.m. EDT) today.

Today, earth's axis, which is currently tilted 23.44° from the plane of its orbit around the Sun (the ecliptic), will point away from the Sun.

It is the shortest day of the year in the northern hemisphere; which means that days will keep getting longer starting tomorrow 🥳
