On the morning of September 1, 1859, the amateur astronomer Richard Carrington sketched an unusual cluster of sunspots, our star erupted in a fierce flash. An unfathomable amount of energy stored in the Sun's magnetic field was released, propelling incredible amounts of energy on a collision course with Earth. Carrington had witnessed a solar flare, and the subsequent coronal mass ejection that would hit Earth. "
Now, in a world increasingly reliant on technology, the consequences A Carrington-type event would cost roughly $ 2-3 trillion
Professor Loeb Told Express.co.uk: "A Carrington-type event would cost roughly $ 2-3trillion [£1
"This includes damage to global supply chains, communication satellites, electric power grids and so on
The Sun has a 11 to 12 year cycle, oscillating from solar

The frequency of prominences – flares that we see on the Sun's surface – increase as we reach solar
These are very violent events where magnetic fields cross each other, releasing huge amounts of energy.
And the Sun occasionally releases a blob of hot plasma which occasionally hits the Earth.
The last time time this occurred, in 2014, a big eruption missed the Earth by only nine days s.

Professor Loeb has studied the repercussions and ways of mitigating another Carrington Event.
He told Express.co.uk: "
"If the equivalent of a Carrington took place today, it would cause damage to infrastructure that did not exist in 1859
"The damage would be even worse today because there would be even more infrastructure."
"Carrington-like event in the next century."

"On the time scale of a century, it will definitely take place. "
Professor Loeb believes the most innovative mitigation would be to deflect this blob of energetic particles away from the Earth.
He said:" We would create a magnetic field by deflecting charged
"And it would be at the lagrange point, because there is no gravitational acceleration at this location."
"This would be a major engineering project worth it, if you compare it to the cost of damage.
"The cost of the magnetic deflecto r project is £ 100billion [£79.4billion]given that the cost of taking 1kg into space costs about $ 1,000 [£795].
"But I think it will take first Carrington-like event of the modern era of technology before politicians act.
Professor Loeb, last year made headlines around the world with his theory the Oumuamua extrasolar asteroid could be an alien ship.
