Below are images of Earth taken 6 days ago (Dec 21, 2025) and on June 19, 2025 near the last Summer Solstice, from the direction of the Sun.

The tilt of earth's axis at these two extreme points can be seen clearly.

These images were taken by the NASA DSCOVR satellite, which is located 1.5 million km away at the Sun-Earth L1 Lagrange point.

The tilt of earth's axis is very obvious from the 2 images.
