actually, when i was looking at that pic and reading UT's description the first time, i thought it looked like a bigger area than the earth's diameter. I was told in science that a million earths could fit inside the sun. or something.

We aren't in a courtroom over this matter yet, are we? That the statement from APOD is technically true doesn't mean it is not misleading and not both ignorant and promoting further ignorance.
As for how many Earths could fit inside the Sun, your science teacher was basically correct. Assuming face-centered cubic packing of Earths (the best possible), 74% of Sun's volume will be filled, which gives us about 997500 Earths. You'd have to compress them slightly to fit the whole million, but I am sure gravitation will take care of that. :)

May be so. But I'd rather look like an idiot nitpicking than do it being ignorant about something.

Well paranoid, 50 to 100 Earths, huh? Thanks, that’s very enlightening.
Now the web site says the whole prominence is about 300,000 km long. The distance from the Sun’s surface appears to be about 1/6th of that or about 50,000 km. You say the Earth is 12,800 km in diameter? I believe you. So if I divide 50,000 km by 12,800 km, I get just over 23 Earths in there.
Since you are obviously an educated person, would you be kind enough to explain what I’m doing wrong.

I guess, pretty much everything. To start with, your math skills seem to be the worst here. :) You appear to have some problems with division in particular.
Getting back to your implied question, let me explain. First, I doubt the 300,000 km estimate given by UT. Since we know how big the Sun is and that the photo is taken almost from Earth orbit, the prominence appears to be about twice as long. Second, we don't know the position of the prominence in respect to the Sun. It might be significantly closer to Earth than the Sun is and that would greatly increase the distance. The lower bound appears to be around 20 Earths (not 50/12.8~20, mind you), but I believe it's unlikely that the prominence is exactly at the side of the Sun, so I gave a higher estimate.

Yes, especially when the corrections are put so delicately and sensitively.

I think they match the gravity of the mistake.

You are welcome. And thank you for linking to this great image in the first place.
