Giant Solar Tendril of Death Erupts on Sun’s Surface!

It’s a good thing remote cameras and astrological observatories are allowed to look directly at the sun, otherwise we Earth-dweller’s wouldn’t get to witness terrifying events like this!

Last week NASA’s Solar Dynamics Observatory captured the above awe-inspiring footage of an immense solar flare. The BBC referred to this as a “tendril of plasma” which in space lingo is known as “solar prominence.”

These phenomena are generally about 430,000 miles long and are anchored to the Sun’s photosphere. And if this wasn’t terrifying enough, scientists are still researching how and why solar prominences occur in the first place.

Some solar prominences are so large that they could envelope not only our little planet, but bad boy Jupiter too!

Check out this comparison via the Solar Dynamics Observatory:

Earth is 92 million miles away, this poses no danger at all to us. Sunspots, on the other hand, could produce nasty EM storms that do things like kill every satellite in orbit or cause power surges in high tension wires that fry transformers. We are overdue for a century long wait to end for a really nasty sunspot cycle. That is something to worry about.

Please! It is "astronomical observatorvatories" -- high tech facilities which do real science. The "astrological observatories" referenced in the article would be bizarre modern-day relics from an earlier age of superstition.

Lightbringer,

Sunspots and prominences are closely related. Plus it is the plasma in the Solar Storms that cause problems back on Earth, not the EM. The plasma from the elevated solar wind during a sotrm causes changes in the magnetosphere near the Earth, and that is what causes the problems.

I wonder what stellar flares look like from the perspective of potentially habitable worlds around stars like Proxima Centauri or UV Ceti, where not only must the planet be very close to be warm enough for life but the flares are significantly larger than the sun's (UV Ceti has been observed to increase in brightness by a factor of 75 over about 20 seconds).
