Sometimes in order to test a theory about how processes work below the surface of the Earth, scientists need to recreate minerals found in very specific circumstances. This photograph was taken through a binocular microscope during a critical step of the creation of artificial peridotite: extraction of the artificial peridotite from its gold capsule. The sample is a little cylinder, 3 mm long with ...[Read More]

Space weather is a ubiquitous, but little known, natural hazard. Though not as tangible as a volcanic eruption, storm or tsunami wave, space weather has the potenital to cause huge economic losses across the globe. In Europe alone, the interaction of solar wind with our planet’s magnetosphere, ionosphere and thermosphere, could lead to disrutions to space-based telecommunications, broadcasti ...[Read More]

A visualisation of an electrical charge moving through plastic. Machines are used to discharge electricity onto surfaces then metallic powders are used to visualise the static. The image is then exposed onto a photopolymer plate and etched with ink. Is is called the photogravure process. Description by Nicolas Strappini, after the description on imaggeo.egu.eu. Imaggeo is the EGU’s o ...[Read More]
