Myth busted: Total solar eclipses don't release special, blinding radiation, NASA says
LIVESCIENCE ^ | 4/8 | Ben Turner

Today's total solar eclipse won't produce any especially harmful radiation, but that doesn't mean you should look at it with your bare eyes.

Today (April 8), a total solar eclipse will sweep across 15 U.S. states, plunging a 115-mile-wide (185 kilometers), 10,000-mile-long (16,000 km) path into sudden darkness as the moon's enormous shadow glides across the face of the sun.

It's a cosmic coin trick that has always evoked feelings of both awe and dread in skywatchers down on Earth, and eclipses have been interpreted throughout history as messages from gods, bad omens or heralds of imminent apocalypses.

In the present, scientists know a lot more about eclipses (and are even chasing today's eclipse down in jet planes) but that doesn't mean that all of humanity's fears around the celestial events have been assuaged.

Thankfully, many of these myths have already been debunked by NASA, including one popular claim that total solar eclipses produce especially harmful rays that can cause blindness.

"During a total solar eclipse when the disk of the moon fully covers the sun, the brilliant corona emits only electromagnetic radiation, though sometimes with a greenish hue," NASA wrote in a blog post for the 2017 Great American Eclipse. The sun's corona — its hot, outer atmosphere — peeks out from around the moon during a total eclipse and will look spiky, like a hedgehog, due to this radiation.

“Special blinding radiation” who comes up with this? Really it’s just:
A - you really shouldn’t look straight at the sun anyway
B - the dimming makes your pupils dilate but the sun is still really bright if you’re looking at it direct, which refer to A

Michael Snyder will be disappointed that there will not be any death and destruction associated with the eclipse.

There will be, unfortunately, death and destruction in America, but not from the wrath of God. It will be from the treasonous conduct of the Biden administration.

The danger of watching a solar eclipse is that the ambient light gets darker, so your eyes dilate wider. But the surface of the sun that is still visible is just as bright as before. So it can burn tiny holes in your retina that only happens if you stare into a laser pointer.

The point is that looking at the sun can cause permanent eye damage. What happens during eclipses is that the obscuring of most of the sun makes it feasible to look at it for seconds without your eyes watering too much. That’s what causes the damage. Instead of a nanosecond during a normal day, people are able to look at the sun for many seconds during an eclipse. That’s what causes the damage - prolonged exposure. It’s a little like the person unable to feel pain being burned on a hot stove.

I used an arc welding hood. No problems.

There’s a host covering the sun!

It was a Y-U-G-E nothingburger. Boring.

Yes...

I had my glasses slip and the light was intense.

As the light dimmed, and nocturnal behaviors kicked in, I did want to fire up the grill and have a beer.

Same here, used some old welding helmets for anyone who wanted to see it, just made sure lens were at least a 14. It was pretty cool, almost a total with just a sliver exposed.

Just for a moment at the height of the eclipse you could catch a glimpse of Witches and Warlocks and Trolls and Dragons..... 🐉

I was going to post something similar about Snyder. He wasn’t alone, though — a whole bunch of folks, including FReepers, were predicting/expecting a whole host of things.

I’m a bit disappointed... Where are the earthquakes, CERN generated portals, Iran nuking Israel, the Rapture, dogs and cats living together...

The corona is much hotter than the photosphere, which is at 5800 K. The plasma is pumped to a much higher temperature ( order of a million K) by magnetic fields coupled to convection currents within the body of the sun.

So the central frequency of the radiation from this super high temp component of the corona is above the visible spectrum. To be specific, Wiens law gives the wavelength peak as inversely proportional to the temperature, and our yellow disc of the sun has its peak at 500 nm so the peak for the pumped corona, which is 20x as hot is at 1/20th of that wavelength, which is about 25 nm, which is hard UV. https://en.wikipedia.org/wiki/File:Electromagnetic-Spectrum.svg

If you watch the sun during totality you can get a lot of hardUV without seeing a lot of brightness.

So here is where if there is any dangerous radiation during totality it would be UV, and soft X rays. These are there when the disk of the sun is present too but we wouldn’t stare at that because the brightness would hurt our eyes.

I asked a flight surgeon about what you need in protective glasses and he told me that your retina can get over UV like your skin can get over a sunburn. So I agree with the other response that UV protective glasses should be worn during totality. He said that the permanent damage from looking at the sun is (like someone said on the tread) an actual thermal burn, as someone here said, where the lens of your eye is the magnifying glass and your retina is the anthill. But your retina doesn’t have the heat sensitive nerves like your skin does so you might not stop in time.

It was awesome in cape girardeau Missouri. Even saw solar flares.

I guess those Eurofags at CERN got bummed out with the dark matter crap they are trying to “accelerate”/find/pimping in regards to the eclipse today. Guess they need to host another Luciferian festival to energized themselves or whatever with the wealthy Eurofags for the grift.

Awesome! Cannot wait for the pictures!
In 2017 we were careful witness to alllllmost totality and it was an amazing experience, birds quieted, winds stilled, darkness during the day.
Beautiful.
Today here, a lovely day, but no real discernible changes.
Thank you FRiend, thank You Lord!
