STAR detector and particle tracks (IMAGE) DOE/Brookhaven National Laboratory Caption Scientists can track the trajectories of particles emerging from heavy-ion collisions at the Relativistic Heavy Ion Collider (RHIC) using the STAR detector. This composite image shows the house-size detector and sample particle tracks from a high-energy head-on gold-gold collision.
