Here are some of our favourite entries:

Safety first – particles from outer space second! In this picture you see Claire Antel (left) and Lydia Brenner (right) in the lab of the FASER Experiment at CERN. This new dark matter detector will be installed 100 meters underground before the end of this year. This picture was taken on the 10th of July when we for the first time managed to test the detector by measuring cosmic ray particles. You can see the normal protective gear we always have to wear, such as steel-reinforced work boots and helmets, as well the face-masks that are now mandatory in all indoor work areas at CERN. You can also see that we have to maintain distance at all times, which makes working on the same small machine, between us in the picture, slightly more complicated, but we managed. Submitted by Lydia Brenner

Luca Naticchioni (INFN) and Maurizo Perciballi (INFN) working on the installation of a new underground seismic station at the candidate site for the Einstein Telescope in Sardinia, Italy (Sos Enattos – Lula, August 2020). Submitted by Maurizio Perciballi.

Marco La Cognata is mounting experimental set-up for a Nuclear Astrophysics experiment at INFN Laboratori Nazionali del Sud (in Catania, Italy). The 27Al beam for this experiment was the first delivered in Italian laboratories after the lock-down. Taken in May 2020. Submitted by Sara Palmerini.

Part of the SMOG2 group installing, in front of the LHCb detector, the first gas fixed target at the LHC. LHC will have not only beam-beam but also beam-gas interactions. A new frontier for quantum chromodynamics and astroparticle physics, LHCb cavern, CERN 6th of August 2020. Submitted by Pasquale di Nezza.

And finally, our winning photo is:
