Exhibition

An illustrative exhibition of the scientific discoveries for which gravitational lensing has been used since 1919 has now been installed in conjunction with other historical exhibitions at Roça Sundy, in the national museum in São Tomé, and at the Museo do Eclipse in Sobral, Brazil. The following selection of displays (now in São Tomé and Sobral) was funded by the Royal Observatory Edinburgh.
