Earth’s atmosphere, particularly its upper layers, remains one of the least understood regions of the planet. Despite extensive research on the lower atmosphere, scientists have struggled to collect reliable data on the mesosphere and higher regions. This atmospheric layer, which sits between the stratosphere and space, has earned the moniker “ignorosphere” due to its inaccessibility. … Read more
Iron, a primary component of the Earth’s core, exhibits unique behaviours under extreme temperatures and pressures. Recent research has examined its melting temperature and phase stability under conditions mirroring those at the Earth’s core. Findings from advanced experiments involving ultrafast X-ray absorption spectroscopy have highlighted significant revelations about the structural and thermal properties of iron. … Read more
