Neither humans nor birds, Earth will be destroyed in just a moment due to..., know what is Miyake event
Solar storm- Representative image We all have heard since our childhood that a day will come when everything on Earth will be destroyed. Adding to the theory, it is also said that 'Mahapralaya' occurred on Earth millions of years ago, leading to destruction of everything on Earth. However, this story is about an event, which is assumed to be more dangerous than this 'Mahapralaya' in our universe. Largest-ever solar storm In a massive discovery reported in 2023, an international team of scientists discovered a huge spike in radiocarbon levels 14,300 years ago. The scientists got to the result by analysing ancient tree-rings found in the French Alps. As per the report, scientists discovered that the radiocarbon spike was caused by a massive solar storm, the biggest ever identified, as per a report carried by IANS. The largest and the directly-observed was a solar storm that occurred in 1859. It is known as the Carrington Event and was caused massive disruption on Earth. As a result of the storm, telegraph machines were destroyed, creating a night-time aurora so bright that birds began to sing. Details on Miyake Events It has also been known that nine such extreme solar storms — known as Miyake Events — have been identified as having occurred over the last 15,000 years. As per the IANS report, the most recent confirmed Miyake Events occurred in 993 AD and 774 AD. However, it also reported that this newly-identified 14,300-year-old storm is however the largest that has ever been found. However, the Miyake Events would have been a staggering entire order-of-magnitude greater in size. Extreme solar storms Most importantly, the scientists have warned that it is critical to understand the future risks of events like this, to enable us to prepare, build resilience into our communications and energy systems and shield them from potential damage. 'Extreme solar storms could have huge impacts on Earth. Such super storms could permanently damage the transformers in our electricity grids, resulting in huge and widespread blackouts lasting months,' said Tim Heaton, Professor of Applied Statistics in the School of Mathematics at the University of Leeds in the UK.

Blast from the Sun 14,000 years ago was so powerful trees still remember it
Scientists have uncovered evidence of a colossal solar storm that struck Earth more than 14,000 years ago, an event so powerful that its effects are still recorded in tree rings in the upcoming July 2025 issue of Earth and Planetary Science Letters, this ancient storm, which occurred around 12,350 BC, dwarfs any solar storm recorded in modern history and would wreak havoc on today's technology if it were to happen as a "Miyake Event," this storm far surpasses the infamous Carrington Event of 1859, previously considered the benchmark for extreme solar activity. Miyake Events are identified by spikes in carbon-14 levels found in tree rings—carbon-14 being a radioactive isotope produced when solar particles collide with Earth's atmosphere. Since the first discovery by Fusa Miyake in 2012, at least six such events have been confirmed, including those in 774 AD and 993 12,350 BC Miyake Event stands out due to its immense scale and the challenges it posed to scientists trying to interpret it. The spike in carbon-14 was detected in Scots Pine trees along France's Drouzet River, and corroborated by matching beryllium-10 levels in Greenland ice cores, confirming the storm's global interpreting these signals was complicated by the fact that the event occurred during the Ice Age, a period with very different atmospheric and climatic conditions compared to the relatively stable Holocene epoch when most other Miyake Events tackle this, researchers Kseniia Golubenko and Ilya Usoskin from the University of Oulu, Finland, developed a specialised chemistry-climate model. This model accounts for Ice Age variables such as ice sheet boundaries, sea levels, and geomagnetic fields, enabling accurate analysis of the ancient findings reveal that the 12,350 BC storm unleashed a solar particle bombardment 500 times stronger than the largest solar particle storm recorded by satellites in put this in perspective, during the 2005 event, a passenger flying over the poles might have received a year's worth of cosmic radiation in one hour; during the Ice Age event, the same dose would have been delivered in just eight discovery not only redefines the worst-case scenario for space weather but also opens the door to studying even older solar storms, potentially uncovering more extreme events hidden in Earth's ancient Watch
