9/22/2005: Red flash moon

Katkeeper points out that the IotD has featured a green flash on the sun before so why not today's ApoD, which is a red flash on the moon? OK.

You can see more green color at the top and more red at the bottom, too. ApoD explains: While the long sight-line through the atmosphere filters and reddens the moonlight, it also bends different colors of light through slightly different angles, producing noticeable red (bottom) and green (top) lunar rims. Also captured here floating just below the Moon is a thin, red mirage (inset) -- in this case, an atmospherically magnified and distorted image of the red rim.

That's cool.

Not that I need another photographic holy grail to seek, after striving to capture a green flash at sunset. I never did catch one myself, but I thoroughly enjoyed the quest. Nice picture. Thanks, UT.

I'd heard of the harvest moon and the hunters moon but never heard of a Goatse moon. :eek:

Very cool.

:biggrin: TW will be along to explain why that's all BS

How much light passes through the earth's atmosphere and illuminates the moon has been an ongoing experiment for some decades now. Research has suggested a substancial decrease in light absorbing materials in earths atmosphere. If air is dirtier, then global warming has occurred slower.

Also part of this experiment is measuring light intensity of the sun. It too varies. Numerous variable. Equipment that must remain calibrated for minor variations of light intensity over generations. Complex study.

Must be my turn in the box...

Hey, tw. The moon is illuminated by the sun, not by the earth. The clarity of the atmoshphere affects the visibility of the moon from earth of course.

I have read nothing that suggests the conclusion that dirtier air is evidence of slowed global warming.

I did not need that thought ...

You're all wrong!!!! Everyone knows the moon is made of red cheese.


Jeeze!

Mmmmm... Gouda!

I did not know what Goatse was. Thanks to Google, and xoxoxobruce, now, I do.

I learn something new every damn day.

I'm sorry you had to find out what Goatse is. You didn't actually see him, did you?

Oh my god. I didn't know what Goatse was either. I just went and looked it up.

I cannot unsee what I saw.

We've all had that exact same wish.

And somehow, the power of the image is such that every time from here on out that someone so much as mentions it, you'll vomit in your throat a little bit. Every single time.

I feel your pain.

(N.B. the upside is that while the image swims to the fore of your consciousness when you see the name, it does not remain in the front of your head all the time. It doesn't stick there, like the Barney Song or The Chicken Dance Tune. Repression is a protective mechanism for the brain. The human brain is a miraculous machine. This proves it.)

Such is the power of Goatse. It's actually quite amazing. You say things like, "I'm sorry you saw Goatse." other people say things like "I wish I could go back in time and not see Goatse." The message couldn't be more plain. YOU WILL BE SORRY IF YOU LOOK AT GOATSE.

And yet others will come, read those comments, be curious, and actively seek out Goatse. Goatse is a power that can't be stopped. Almost like a black hole. Once you have heard the mention of Goatse, you have crossed the event horizon, and nothing you can do will keep you from being sucked in. :eek:
