Extragalactic cosmic ray Extragalactic cosmic ray Extragalactic cosmic rays are very-high-energy particles that flow into the Solar System from beyond the Milky Way galaxy. The energies these particles possess are in excess of 10 eV. Unlike solar or galactic cosmic rays, little is known about the origins of extragalactic cosmic rays. This is largely due to a lack of statistics: only about 1 extragalactic cosmic ray particle per square meter per year reaches the Earth's surface (see figure). There are many ideas about which processes may be responsible for cosmic rays with such high energies. In the 'bottom-up' approach, cosmic rays gain more
Beyond the Years Beyond the Years Beyond the Years () is a 2007 South Korean drama film. Celebrating director Im Kwon-taek's 100th film, it is based on the short fiction "The Wanderer of Seonhak-dong" by Lee Cheong-jun, and was presented at the 2007 Toronto International Film Festival.
