One hundred years after the publication of Einstein’s Theory of General Relativity, the UN General Assembly declared 2015 the International Year of Light and light-based technologies. Around the world, the year is being celebrated with programmes and events showcasing light as the source of life, peace and science. CERN has been joining in the festivities; with events showcasing “light as luminosity” in its High-Luminosity LHC (HL-LHC) upgrade project as well as its involvement in the SESAME synchrotron project in Jordan.
This article is a republication from the CERN Bulletin. Since its discovery in 2012, the Higgs boson has been in the spotlight for both experimentalists and theorists. In addition to its confirmed role in the mass mechanism, recent papers have discussed its possible role in the inflation of the universe and in the matter-antimatter imbalance.
Hosted at CERN, UNITAR’s UNOSAT programme examines global satellite imagery for humanitarian use. Whether providing maps for disaster response teams or assessing conflict damage to help reconstruction, the detailed reports provided by the satellites are vital tools for aid workers. But how can satellite imagery help during a health crisis like the Ebola outbreak?
