Total Solar Eclipses visbile only from narrow view because The Moon, much smaller than the Sun, casts a limited shadow. During a total solar eclipse, only the small area covered by the darkest part of the Moon's shadow (the umbra) experiences complete darkness.As the Moon orbits Earth, this shadow traces a narrow path across the Earth's surface. Only observers within this specific path can witness the total solar eclipse. Those outside this narrow path see only a partial eclipse or none at all.
