The sun has ‘gone blank’ and there could be another ice age on the way
The sun has gone “completely blank” for the second time this month suggesting that Earth could be heading for a mini ICE AGE. Earlier this month, there were no sunspots on the massive star’s surface for four days – something which hadn’t happened since 2011. This has since happened again. A lack of sun spots is totally normal, but it does hint that the sun is heading for its next “solar minimum phase”.
The next solar minimum phase is expected to take place in 2019 or 2020, saysmeteorologist Paul Dorian of Vencore Weather , who expects to see an increasing number of spotless days over the next few years.
The last time the sun saw a such a long phase with no sunspots, it ushered in what scientists refer to as a the ‘Maunder Minimum’ back in 1645.
This caused temperatures to plunge dramatically, and even resulted in the Thames freezing over.
Some experts think that a similar mini ice age could be coming again soon.
The solar phenomenon could even prove dangerous for astronauts, says Paul Dorian.
During these spotless phases of the sun, extreme ultraviolet radiation drops, resulting in lower aerodynamic drag as the Earth’s atmosphere cools and contracts.
The lower drag can cause space junk to accumulate in orbit, which could result in a collision with the International Space Station or other spacecraft.
