Is the dark side of the earth protected from the risks of solar flares?
Nope
Solar flares don't work like "A massive blob of hot gas hitting the bright side of the Earth"
It's more similar to "A stream of ionized plasma that 'hits' the Earth's magnetic ...

What forces expelled these huge clouds, then blocked further progress, yet allowed it to maintain its threads?
This was a coronal mass ejection.
Those 1973 astronomers weren't looking at the picture correctly. They didn't have the tools at that time to look at the picture correctly. Coronal mass ejections (...

How does a Super-Massive Black Hole 'flare'?
The flare happens just outside the black hole. Matter which aproaches a black hole but not perfectly straight on doesn't fall into it immediately. It gets pulled around the black hole, just as a ...

Where do Coronal Mass Ejections go?
Coronal Mass ejections are not easy to detect from Earth (until they hit the ionosphere and cause a geomagnetic storm) The first was discovered by a space-based solar observatory in 1971. They are, ...

Does coronal mass ejection include radiation at optical wavelengths?
Coronal mass ejections consist of a very hot, but thin, plasma. Their very weak intrinsic emission would be dominated by ultraviolet and X-ray lines and bremsstrahlung continuum. There is very little ...

Does Earth's magnetic field become stronger when a solar flare hits?
No, but the magnetic dipole of Earth has a field strength that increases with closer distance. On the direct line between Earth and Sun the magnetic field strength is always $B(r) = M/r^3$ where $M$ ...

Is it possible for a solar flare in one star to influence the chances of a solar flare in another star?

Can hot Jupiters cause solar flares?
Sun is more than one thousand times the mass of Jupiter, so it seems unlikely that even a very close approach by a "hot Jupiter" to its host star would cause a flare, and especially not a superflare.
