Space view of Earth’s magnetic rocks

Media captionSensing the magnetism of rocks from orbit is very challenging It is the best depiction yet of the magnetism retained in Earth’s rocks, as viewed from space. The map was constructed using data from Europe‚Äôs current Swarm mission, combined with legacy information from a forerunner satellite called Champ. Variations as small as 250km across […]

LHC: Five new particles hold clues to sub-atomic glue

Image copyright EQUINOX GRAPHICS/SCIENCE PHOTO LIBRARY The Large Hadron Collider has discovered new sub-atomic particles that could help to explain how the centres of atoms are held together. The particles are all different forms of the so-called Omega-c baryon, whose existence was confirmed in 1994. Physicists had always believed the various types existed but had […]
