This glass was an important part of the equipment Michel Mayor used to search for exoplanets – planets in solar systems other than ours. Stars with planets display a slightly rocking motion. As a result of the Doppler effect, the movement causes the color of the star to change – its spectrum shifts. To study this, a spectrograph coupled with a telescope was used. The glass, which belonged to the spectrograph, served as a template to effectively compare many spectral lines at the same time. If the entire spectrum shifts, the light passing through increases or decreases, depending on the amount of incident light covered by the dark spots on the glass. This glass was the first used when Mayor began investigations in 1977 that would eventually lead to the discovery of exoplanets.
Michel Mayor donated the glass template to the Nobel Prize Museum in 2019. - Pristagare
