🌑 Total eclipses

Total solar eclipse of 29 May 1919

El eclipse que cambio la fisica: las medidas de Eddington en Principe y de la expedicion de Sobral (Brasil) confirmaron que la gravedad desvia la luz, y con ello la relatividad general.

The Earth · Moon · Sun system that day

The same eclipse seen from outside. The Moon’s position, the shadow cone and the umbral spot come from the official Besselian elements — not from approximate ephemerides — so the shadow lands exactly where it will land. Drag to rotate, scroll to zoom.

How to watch it without hurting your eyes

⚠️
Throughout the partial phase, even with a sliver of Sun left, looking without protection causes permanent retinal damage. Use only ISO 12312-2 eclipse glasses. The one exception is totality: while the Sun is fully covered, and only inside the path, you can and should look with the naked eye.
