It's not just the world that's gone into lockdown, the sun's activity has also fallen and scientists warn this could cause freezing weather, earthquakes and famine.

As the sun enters a period of "solar minimum" its activity has decreased, scientists report there have already been 100 days where the sun has displayed zero sunspots.

Sunspots are "cool planet-sized areas on the sun where intense magnetic loops poke through the star's visible surface," explains Spaceweather.

This means were could be entering one of the deepest period of sunshine recession which could trigger long periods of cold, famine and other issues.
