Ancient star map hidden under reused pages for centuries finally decoded by scientists using X rays

X ray scans revealed possible Hipparchus fragments

Researchers used advanced X-ray imaging to uncover ancient astronomical fragments hidden beneath medieval writings, preserved only because older parchment was reused. The team believes the recovered pieces may connect to Hipparchus, shedding light on early efforts to systematically catalog the night sky. It is a rare snapshot of how ancient science survived by accident, then re-emerged through modern technology.
