Where do these materials on the Sun come from, if not nothingness?
In this video, I see that for hours, it seems that the flow keeps going from the 11h direction to the Sun's surface - while there looks like nothing is coming to the top of the loop to provide a ...

Where do Coronal Mass Ejections go?
Due to magnetic fluctuations in the Sun's corona, the Sun produces Coronal Mass ejections (CMEs).
Where does the matter from these CMEs go if they don't hit any celestial object? Are they visible from ...

Strength of the relationship between very large solar flares, coronal mass ejections, and solar proton events?
In the years 774-775 and 993-994, there were large peaks in Earth's atmospheric radiocarbon (14C) concentration. While the cause was initially disputed, Mekhaldi et al.'s 2015 study of annually ...

Solar flares/CME dangers to life?
I know a repeat of the 1859 Carrington Event (coronal mass ejection) would pose a severe risk to power grids and telecommunication networks but wouldn't pose an immediate threat to life.
If a large ...

Detecting anomalies from the sun from home
I was wondering if there are any ways for some amateur to detect let's say solar flares or CMEs from home. What kind of hardware would you need in order to have chance of seeing/measuring those?
I ...

Does Earth's magnetic field become stronger when a solar flare hits?
This curiosity arises as follows: when ejecta from a strong solar flare hits Earth, will the Earth somehow counter its impact with a stronger magnetic field.
Or, earth's magnetic field as limited ...

Does coronal mass ejection include radiation at optical wavelengths?
It is known that during Solar/Stellar Flare, plasma from the corona of the star is released into the space, and travels comparatively slowly.
In an hypothetical situation, does the coronal mass also ...

Are we still in the Solar Maximus stage? Will this winter 2013/14 be a good aurora-viewing season?
I remember reading in 2011 that 2013/2014 would be the peak of the current solar maximus, but I want to confirm whether that is still ongoing. Will the upcoming winter season be a good time to see ...
