New Observatory Takes Highest-Energy Particle Research to New Heights

As cosmic-ray particles are accelerated by a black hole in this artist's interpretation, they stream toward Earth as very-high-energy gamma-rays. Upon hitting the atmosphere, they produce a shower of particles that rain down on Earth. Most of these particles run out of energy before they hit sea level.
