Lead ion collisions
Lead ion collisions. Particle tracks from the first lead ion collisions seen by the ALICE (a large ion collider experiment) detector at CERN (the European particle physics laboratory) near Geneva, Switzerland, on 7th November 2010. Each collision, produced after the ions had been accelerated to an energy of 287 TeV (tera electron volts) by the large hadron collider (LHC), leads to the production of thousands of subatomic particles. The tracks are colour-coded according to energy from low (blue) to high (red). Lead ion collisions are expected to produce quark-gluon plasma, a primordial state of matter thought to have been present in the Universe microseconds after the Big Bang. Shaded areas are elements of the detector

EDITORS COMMENTS
In this image, we witness the first lead ion collisions ever recorded by the ALICE experiment at CERN, the European Organization for Nuclear Research, located near Geneva, Switzerland. On November 7, 2010, these ions, each carrying the mass of approximately 208 lead nuclei, were accelerated to an astounding energy of 287 TeV (tera electron volts) by the Large Hadron Collider (LHC). The resulting collisions produced a cascade of thousands of subatomic particles, which are vividly depicted in this photograph. The particle tracks are color-coded according to their energy, with low-energy particles appearing in blue and high-energy particles in red. Lead ion collisions are anticipated to generate quark-gluon plasma, a primordial state of matter believed to have existed in the universe mere microseconds after the Big Bang. The shaded areas in the image represent various elements of the intricate ALICE detector. Quark-gluon plasma is a fascinating and crucial aspect of modern physics, as it is a unique state of matter in which quarks and gluons exist in their deconfined form. This discovery could potentially shed new light on the fundamental structure of matter and the evolution of the universe. The ALICE experiment, an inner tracking system designed specifically for heavy ion collisions, plays a pivotal role in the exploration of this intriguing phenomenon. The Large Hadron Collider, a marvel of 21st-century technology, has revolutionized our understanding of particle physics by providing scientists with the ability to study the behavior of subatomic particles at unprecedented energies. This image serves as a testament to the groundbreaking research being conducted at CERN and the ongoing quest to unravel the mysteries of the universe.
