Samuel Ting won the Nobel prize for physics for discovering the subatomic J/? particle. He’s been on La Palma for a conference about the Alpha Magnetic Spectrometer which is on the International Space Station. ( It’s looking for antimatter in cosmic rays, to learn more about dark matter and the formation of the Universe.) The Cabildo (the island council) took the chance to include him in their Stars of Science lineup. The idea is to have stars along the sea front promenade, rather like Hollywood Boulevard, but with stars of science rather than film.
After the formal presentation there was a party in the orange tree courtyard. These orange trees were planted on the day the observatory was inaugurated.
