The most stable source of light in the world

30 septiembre 2015

In order to be able to detect planets comparable to Earth, the CHEOPS satellite, which will be sent into orbit at the end of 2017, must be able to measure the luminosity of a star with inimitable accuracy. In order to test CHEOPS detectors researchers need a stable source of light. However there was no instrument capable of producing a light source with sufficient stability to be used as a reference — until today. A team from the University of Geneva (UNIGE), Switzerland, has just filed for a European patent.
