Sun might plunge into ‘deep solar minimum’, which could cause part of Earth’s atmosphere to collapse

SCIENTISTS suspect the sun is on the verge of a “deep solar minimum”. It’s about to shower us with rays so intense that part of our atmosphere will collapse.

THE sun might soon batter us with a shower of deep space rays so intense, it could cause part of our atmosphere to collapse.
Space scientists reckon we are on the verge of a “deep solar minimum,” which is a period of low activity, reports The Sun.
Unlike the name suggests, this could cause an outer layer of the atmosphere called the thermosphere to contract — and it’s not entirely clear what the effects of this could be on our planet.
Professor Yvonne Elsworth at the University of Birmingham in England believes that a “fundamental change in the nature of the [sun’s magnetic] dynamo may be in progress.”
It’s backed up by NASA’s Solar Dynamics Observatory’s daily snaps, which have shown a spotless sun for 44 days in a row.
This led scientists to believe that it’s nearing a tumultuous period not seen since 2008.
Solar minimums are known to spark lots of cosmic ray activity that can penetrate our atmosphere.
