Are sunspots active now?
NASA says we started a new solar cycle in late 2019, and it’ll get more active in the coming years, particularly a few years from now. Sunspots are an indicator of more activity and more magnetic activity on the sun. The more sunspots the sun has, the more active it is.

Do sunspots make Earth warmer or cooler?
Sunspots have been observed continuously since 1609, although their cyclical variation was not noticed until much later. At the peak of the cycle, about 0.1% more Solar energy reaches the Earth, which can increase global average temperatures by 0.05-0.1℃. This is small, but it can be detected in the climate record.
Is the sun getting bigger?
The Sun has increased in size by around 20% since its formation around 4.5 billion years ago. It will continue slowly increasing in size until about 5 or 6 billion years in the future, when it will start changing much faster.
Do sunspots affect weather?
If sunspots are active, more solar flares will result creating an increase in geomagnetic storm activity for Earth. Therefore during sunspot maximums, the Earth will see an increase in the Northern and Southern Lights and a possible disruption in radio transmissions and power grids.
What year will the sun explode?
Scientists have conducted a lot of researches and study to estimate that the Sun is not going to explode for another 5 to 7 billion years. When the Sun does cease to exist, it will first expand in size and use up all the hydrogen present at its core, and then eventually shrink down and become a dying star.
