IceCube is a particle dectector located at the South Pole and it records the massless sub-atomic particle Neutrino. IceCube is the largest Neutrino detector.
The electron is the subatomic particle located farthest from the nucleus of the atom.
CERN, the European Organization for Nuclear Research, was in the news recently due to the completion of the Large Hadron Collider (LHC) upgrade. The LHC is the world's largest and most powerful particle accelerator, and the upgrade aims to increase its luminosity which will allow scientists to study particles with greater precision.

The dense particle is called a nucleus. It contains protons and neutrons and is located at the center of an atom.
Neutrons are located in the nucleus of an atom and have no charge
it is located around an atom orbiting it
It is called the CERN accelerator complex. The complex consists of the following Particle accelerators: Linear accelerator I & II, Proton Synchrotron Booster, Low energy ring, Proton Synchrotron, Super proton snchrotron, and the Large Hadron Collider (as of Oct 18, 2009.)
