Imaggeo on Mondays: Magnetic interaction

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]

NASA’s Juno mission reveals Jupiter’s magnetic field greatly differs from Earth’s

NASA’s Juno mission reveals Jupiter’s magnetic field greatly differs from Earth’s

NASA scientists have revealed surprising new information about Jupiter’s magnetic field from data gathered by their space probe, Juno. Unlike earth’s magnetic field, which is symmetrical in the North and South Poles, Jupiter’s magnetic field has startlingly different magnetic signatures at the two poles. The information has been collected as part of the Juno program, NASA’s latest mission to unrav ...[Read More]

April GeoRoundUp: the best of the Earth sciences from the 2018 General Assembly

The 2018 General Assembly took place in Vienna last month, drawing more than 15,000 participants from 106 countries. This month’s GeoRoundUp will focus on some of the unique and interesting stories that came out of research presented at the Assembly. Mystery solved The World War II battleship Tirpitz was the largest vessel in the German navy, stationed primarily off the Norwegian coastline as a fo ...[Read More]

GeoTalk: The anomaly in the Earth’s magnetic field which has geophysicists abuzz

Geotalk is a regular feature highlighting early career researchers and their work. In this interview we speak to Jay Shah, a PhD student at Imperial College London, who is investigating the South Atlantic Anomaly, a patch over the South Atlantic where the Earth’s magnetic field is weaker than elsewhere on the globe. He presented some of his recent findings at the 2017 General Assembly. First, coul ...[Read More]

Imaggeo on Mondays: recording the Earth’s magnetic field one grain at a time

The Earth’s magnetic field extends from the core of the planet, right out to space. It is an invisible, butterfly-like, shield which protects us against the harmful particles ejected by solar flares. In addition, it guards us from atmospheric erosion and water loss caused by solar wind. But how do scientists study the Earth’s magnetic field when it can’t be see? Much of what is known results from ...[Read More]

Geoscience hot topics – Part I: The Earth’s past and its origin

What are the most interesting, cutting-edge and compelling research topics within the scientific areas represented in the EGU divisions? Ground-breaking and innovative research features yearly at our annual General Assembly, but what are the overarching ideas and big research questions that still remain unanswered? We spoke to some of our division presidents and canvased their thoughts on what the ...[Read More]
