The last large solar events were in 18, which damaged the telegraph network. Long-distance cables have repeaters to boost the optical signals spaced at intervals of 30-93 miles/50-150 km, which are powered using a conductor.ĭo we know if they’re resilient to solar superstorms? No. “Based on the strength of the CME, in extreme cases, GIC has the potential to enter and damage long-distance cables that constitute the backbone of the Internet.” “ produce Geomagnetically Induced Currents (GIC) on the Earth’s surface through electromagnetic induction,” reads the paper. ![]() While the fiber-optic cables under countries and cities wouldn’t suffer, largely because they’re shorter and grounded, the vast number of subsea links between continents are more vulnerable. The problem, say the authors, are the undersea cables that are the invisible backbone of the Internet. NASA/GSFC/SVS The problem with undersea cables “The networking community has largely overlooked this risk during the design of the network topology and geo-distributed systems such as DNS and data centers,” reads the paper, which predicts large-scale Internet outages covering the entire globe and lasting several months.Įarth's magnetic field shielding our planet from solar particles. However, power grids are designed to mitigate the effect of CMEs. Rarer huge eruptions on the Sun caused by magnetic storms, they create huge clouds of plasma that could damage power grids if they drift our way. The result, of course, is an afterglow known as the aurora-the Northern Lights and Southern Lights.Ĭoronal mass ejections (CMEs) are different. When solar flares come our way, Earth’s magnetosphere accelerates the charged particles down its field lines to the poles. Of course, Earth does have defences against solar flares, intense bursts of radiation that only threaten our planet when they happen on the side of the Sun facing it. ![]()

Thanks for sharing such a informative blog! We are firmly into sweater season now – and colourful designs from ARG Knit’s and Aries meld on point colour combinations with next-gen silhouettes. Knitwear is the perfect gift too, if you’re unsure on someone’s clothing size. If in doubt, opt for a slightly over-sized fit, for a relaxed look that works as well with denim as slim leg pants.
