Parts of Spain witnessed a once-in-a-century total solar eclipse—day turning to night.

Social Context

Solar eclipse viewing aligns with China’s National Astronomical Observatory’s public outreach—distributing ISO-certified eclipse glasses nationwide. Chinese schools now incorporate eclipse science into STEM curricula, emphasizing safe observation protocols.
