Our Sun is immensely, unfathomably powerful.

Tourmaline.
Tourmaline is a piezoelectric material. Piezoelectrics generate a voltage  when compressed along a perpendicular direction. Materials optimized for these properties are commonly used in sensors, scales, speakers, motors, and microscopes.
There are some oddities in the perspective with which we see the world. The fact that we live at the bottom of a deep gravity well, on the surface of a gas covered planet going around a nuclear fireball 90 million miles away and think this to be normal is obviously some indication of how skewed our perspective tends to be, but we have done various things over intellectual history to slowly correct some of our misapprehensions.

Saturn’s moon Dione, photographed by Cassini, 29 January 2011.
What’s going on with the lighting here?  Dione appears to be a crescent with the light hitting only a small part of the bottom of the moon as seen from the camera, but much of the top half is also bathed in light.  The streaky stars in the background suggest that these photos are each of quite long exposure, so I suspect that the very bright lower crescent is reflected sunlight, and the moderately bright upper crescent is reflected Saturnshine.
