A picture I snapped after sunrise on the shortest day of the year. The winter solstice (or hibernal solstice), also known as midwinter, is an astronomical phenomenon marking the day with the shortest period of daylight and the longest night of the year. The axial tilt of Earth and gyroscopic effects of its daily rotation mean that the two opposite points in the sky to which the Earth’s axis of rotation points (axial precession) change very slowly (making a complete circle approximately every 26,000 years). As the Earth follows its orbit around the Sun, the polar hemisphere that faced away from the sun, experiencing winter, will, in half a year, face towards the sun and experience summer. This is because the two hemispheres face opposite directions along Earth’s axis, and so as one polar hemisphere experiences winter, the other experiences summer. Hope you understand all that.
