The Nobel Prize in Physics 2019 was awarded to Michel Mayor and Didier Queloz for the first discovery of a planet outside our solar system, an exoplanet, orbiting a solar-type star in our home galaxy, the Milky Way.
The jewelry shows an exoplanet orbiting its sun-like star. A star which is plated with 23K gold leaf. The jewelry is available in the Nobel Museum’s shop in Stockholm and in my web shop.
