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
From the Sea to the Land Beyond From the Sea to the Land Beyond From The Sea to the Land Beyond: Britain's Coast on Film is a documentary feature film directed by Penny Woolcock, with an original soundtrack by British indie-rock band British Sea Power. The project was originally produced by Crossover and Sheffield Doc/Fest as part of The Space project from the BBC and the Arts Council England. The film was edited by Alex Fry. The world premiere was at the Crucible Theatre at Sheffield Doc/Fest in June 2012, with British Sea Power playing the soundtrack live. It has since been performed at the BFI Southbank,
