Aug 20, 2019 · Our Sun — the source of energy that makes life on Earth possible — has been unusually quiet lately. Astronomers are trying to understand why. Solar observers have been on a wild ride over the ...
It goes through phases of high and low activity, which make up the solar cycle. Approximately every 11 years, the Sun’s geographic poles change their magnetic polarity – that is, the north and south magnetic poles swap. During this cycle, the Sun's photosphere, chromosphere, and corona change from quiet and calm to violently active.
Sep 15, 2020 · This split image shows the difference between an active Sun during solar maximum (on the left, captured in April 2014) and a quiet Sun during solar minimum (on the right, captured in December 2019). December 2019 marks the beginning of Solar Cycle 25, and the Sun’s activity will once again ramp up until solar maximum, predicted for 2025.

Our Sun is a star, like the hundreds that you see at night, only much, much closer. The Sun is a huge ball of hot, churning, unpredictable supercharged gasses called plasma. Held together by gravity, the Sun produces the light and heat that make life on our planet possible. The light from our Sun is surprisingly steady considering that the Sun ...
