A Warmer World May Redraw Earth’s Sunlight Map

by Keith CowingJune 10, 2026June 10, 2026

Sunlight follows a rhythm set by Earth’s orbit and tilt: long summer days, dark winters, and a familiar seasonal cycle from low to high latitudes.

Locations and spectral analysis of marsquakes and impacts. (a) Location of the 418 InSight station (yellow triangle) and events (black stars) used in this study. The S1000a and S1094b are two impact events, and the S0173a and S1222a are marsquakes that occurred at the crustal base or uppermost mantle. The black lines show the great circle of each event. (b)–(e) Spectral analysis of the four events for S0173a, S1000a, S1094b and S1222a. The yellow-shaded areas highlight P-wave signals (red lines) with strengths greater than the noise level (black lines). In contrast to the S0173a marsquake, which exhibits low frequencies (< 1 Hz), the two impact events (S1000a, S1094b) and the largest tectonic marsquake (S1222a) contain rich higher frequency (≥4 Hz) content. More detailed analyses are given in supplementary data S1. -- National Science Review
