What If Earth Gets Hit by a Solar Superstorm?

 What if series  : Part 11

• Have you ever considered what may occur if the Sun suddenly threw a huge energy explosion in Earth's direction? Although it sounds like a scenario from a science fiction film, it is actually science. 

• This phenomenon, known as a solar superstorm, has occurred previously. It could alter the course of history in a single day if it occurred again today. Let's examine this potent natural occurrence and its potential effects on our contemporary lives.

A Solar Superstorm: What Is It?

• The Sun is constantly in motion. In addition to providing us with warmth and light, it releases energy in the form of coronal mass ejections (CMEs) and solar flares. These are massive gas and magnetic field bubbles that are expelled by the Sun. A geomagnetic storm is a phenomenon that can occur when a CME strikes Earth. The majority of storms are minor and harmless. However, the Sun occasionally emits a very powerful one. It turns into a solar superstorm at that point.

The Carrington Incident: An Actual Case 

• This goes beyond theory. The Carrington Event was a solar superstorm that struck Earth in 1859. Satellites, computers, and cell phones did not exist at that time. Even so, some operators were surprised when the storm caused telegraph wires to flare. 

• Near the equator, in locations like Cuba and India, auroras—those stunning northern lights—were sighted. Today, when we rely on technology for everything, picture the same storm striking us.

What Would Take Place Today? 

• Every aspect of contemporary life may be impacted if a Carrington-level storm occurred right now. Here's how: 

 1. The Potential for Power Grid Outages Space weather has a significant impact on electricity systems. Transformer damage and widespread blackouts, maybe spanning entire nations, might result during a powerful geomagnetic storm. Days or weeks may pass before power is restored. 

 2. Satellites May Fail Satellites are used for TV, the internet, phone transmissions, GPS, and weather reports. We might lose many of the services we depend on on a daily basis if a solar superstorm damages or destroys satellites.

3. There Could Be a Communication Problem We risk losing radio transmissions, the internet, and even mobile networks if satellites and electricity are unavailable. Coordinating emergency services would be more difficult. 

 4. Aircraft May Be Grounded To fly securely, airplanes use radios and GPS. Pilots might lose those tools in a solar superstorm. Worldwide, flights may be delayed or canceled. 

 5. ATMs and Banks May Stop Operating Computers and the internet power the majority of banking systems. You might not be able to use ATMs, swipe cards, or make online payments if servers are broken and the power is off. 

 6. Everyday Life Would Be Different Without electricity, there would be no electric water pumps, lights, elevators, or microwaves.

Are We Prepared for This? 

• Numerous nations have space agencies that research the Sun and attempt to provide early warnings when a CME is approaching, such as NASA (USA), ISRO (India), and ESA (Europe). However, after a CME strikes Earth's magnetic field, we might only have 15 to 60 minutes to respond, even with a warning. 

• Power companies have safety mechanisms, and certain satellites are specially protected. In actuality, however, we are not quite prepared for a massive solar storm. One weak link can have a significant impact on all of our systems because they are intricately linked.

Can We Put an End to It? 

• Unfortunately, a solar superstorm is unavoidable. The Sun, which is located roughly 150 million kilometers away, is the source of this natural occurrence. We can improve our preparation: Construct more resilient satellites that can withstand radiation. 

• Improved power grids with safe shutdown capabilities should be designed. Establish backup internet and communication systems. People should be educated so they know what to do in such a situation. It's similar to how we get ready for a typhoon or earthquake. We can lessen the harm, but we cannot stop it.

What Would Happen If It Were Tomorrow?

• Let's consider a plausible situation: 

 Day 1 Morning: A massive solar flare from the Sun is reported by news organizations. It will strike Earth in twelve hours, according to scientists. Evening: We are hit by the storm. Cities' lights go out, power plants trip, and the internet lags or stops working. 

 Day 2: Phones cannot be charged. Banks are not open. No GPS. No television. Stores are unable to accept card payments. 

 Day 3: Backup power is used in hospitals. The water supply is impacted. Air traffic is halted. 

 Day 4: Emergency plans are initiated by governments. Power grids are fixed by engineers. People begin to use solar chargers, radios, and food that has been saved. Depending on the storm's intensity, recovery could take weeks.

Is This Fear Only? Or a Genuine Chance?

• According to NASA, the likelihood of a Carrington-level event occurring over the next ten years is at 12%. That might not seem like much, but in the field of science, it's a significant figure. A solar storm nearly struck Earth in 2012, but it was only nine days away. There would have been significant disruptions if it had struck.
