Related: About this forumA Gigantic Hole Just Opened Up in the Sun
https://www.yahoo.com/news/gigantic-hole-just-opened-sun-160610827.htmlA massive hole opened up in the Sun's atmosphere over the weekend, measuring more than 60 times the diameter of the Earth across at its peak.
Coronal holes like this one, imaged by NASA's Solar Dynamics Observatory, occur when the Sun's magnetic field suddenly allows a huge stream of the star's upper atmosphere to pour out in the form of solar wind.
Over a short period of time, these highly energized particles can eventually make their way to us and if powerful enough wreak havoc on satellites in the Earth's orbit. In rare instances, they can even mess with the electrical grid back on the ground.
Fortunately, in the case of the latest hole, scientists aren't expecting any major disruptions earlier this week beyond minor to moderate geomagnetic storms, as well as the associated auroras borealis in the night sky, according to SpaceWeather.com.

Or some portal was opening and sci-fi got it right!

I didn't see the OP for an hour so I would have been screwn.

No finger-poking allowed.
They only LOOK dark by contrast with the rest of the sun.
Coronal holes are only visible in ultraviolet wavelengths, appearing as dark patches of relatively cool particles in our observations. They're less likely to actually fling solar wind outwards as they're simply an opening, allowing for these photons and electrons to escape.
