What’s wrong with the sun 2020?

“The sun is heading toward solar minimum now. Sunspot counts were relatively high in 2014, and now they are sliding toward a low point expected in 2019-2020. “While intense activity such as sunspots and solar flares subside during solar minimum, that doesn’t mean the sun becomes dull.

What year will the sun explode?
