For over 30 years, scientists have argued about a controversial hypothesis relating to periodic mass extinctions and impact craters
Huge solar storms dodging detection systems on EarthThe current systems to analyse and predict solar storms may not be able to detect large solar flares, scientists report, indicating that this can put both power supply and communication networks at risk on Earth.According to observations from the Tihany Magnetic Observatory in Hungary, the indices used by scientists to assess the Sun's geomagnetic perturbations to the Earth are unable to detect some of these events.
