Re: Why Venus is translucid?
It's just quantum efficiency hysteresis - the CCD's response to light depends on previous exposures, the end effect of which is a bit of ghosting which is quite noticeable here because of the sudden and drastic change from "bright" pixels to "dark" pixels due to Venus. This occurs due to back side charge accumulation ( [link to www.stsci.edu] - the front-side illuminated ccd referred to here does not belong to SDO). SDO's AIA CCDs are indeed back-illuminated CCDs ( [link to www.springerlink.com] ) and are therefore vulnerable to this problem. For the Venus transit, they went to great lengths to make the image cadence even higher than normal, which allowed less time for the charge accumulation to dissipate between exposures than it would during normal operations.

Wonder how long before someone cries shill because this logical explanation doesn't jive with their mentally unstable viewpoints...

Ignore your stage set and get back to acting.

People will report you as delusional, lol

Repeat, you are not on a stage and the earth is not flat

It´s no wonder USA have economic problems, I thought NASA had ULTIMATE technology.

fucking chinese CCD´s

By the way call Industrial Light and Magic for better effects

The way to prove it is a shill is to ask it to publically post it's thought on building 7

If you get a response like it was "accelerated collapse high energy muslim physics"

well at least you have a professional's expert analysis

Re: Why Venus is translucid?
It has an atmosphere, petrolium base, like Naptha.
I would think light is being refracted (bent) around it.
Being as close as it is light rays from the sun are covering alot of it closely, all the way around, illuminating it's atmosphere.

In the sequence which starts at 1:04 why can you can see the sun through the planet?
