I'm pretty sure that it's larger than our solar system by a good margin.

I would say by a very good margin! Can anyone hazard a guess as to the diameter of the disk? Considering angular size and distance from us.. I would guess maybe hundreds of times as big as our solar system!

Well, reading on seds.org seems to indicate they range anywhere from two to eight times the diameter of our solar system, so they're pretty hefty.

Try here

http://www.imagehosting.us/index.php?ac ... nt=1057595

You will need to go thru the process of setting up a free account (my account) and be aware there is a size limit for pictures with the "Free" account. It is approx. 200k. I've had to take a low resolution digital image of my high resolution pictures (640 X 480 pixels) this seems to have no problem with their website.

If you get a premium account then the restriction changes but to what???

Thanks BMAONE23 but I would need to upgrade to post this wonderfully large image.

If anyone has a upgraded account that can post this large file image please let me know and I will email the picture to you.

http://rapidshare.de/ allows 100 MB per file, but it has limited number of downloads.
p.s.: also, http://imageshack.us/ has fewer ads than that of imagehosting.us

Thank you Makc,

All the sites I went to would not post this image for free except rapidshare. It took the large file -no problem.

And........HERE IT IS THE LONG AWAITED IMAGE....

[/quote]Sorry about the delay -- here is the extended mosaic I promised. This has not benn published yet so you are the first outside SSRO to see the image!

It’s beautiful. And if you can dL and zoom in you can still see the hole but it does look a little different here ????

I noticed you have to go through a couple of windows in rapidshare to view the image but it’s free and worth it.

Hello all

Thank you for the image,,,,,,,,,niceeeeee

Martin · Post by **Martin** » Thu Mar 30, 2006 1:28 pm

orin stepanek - on the 1st page you need to choose if you want the free DL or the premium. On the 2nd page you need to scroll down 1/2 way and choose to the alpha or omega site to DL from and then you must type in the 3 characters shown for some verification. If there are DL limits I am unaware. I did not read anything (of course) I was just happy I could post image.

I would be happy to email anyone (virus-free) the picture. Just message me ur email address.

Awesome; and you can see the [hole] just to the right of the three stars used for identification in earlier posts. Thanks Martin. Doesn't really clear up what is going on though. I still think it may be a star forming.

Your right Orin it doesn't clear much up. However, it does confirm something that resembles a "clearing" of material is present -I think

It is a very nice picture. I thank Rick w/SSRO for sharing it with us. I will save for later desktop image

BMAONE23 nice update -ty

I can't seem to locate area in question -is it me or is it not captured in this photo?

BMAONE23 · Post by **BMAONE23** » Tue Aug 22, 2006 1:46 pm

The image has two different sides, both showing the same exact region of space at the same scale. On the right side image, the Visible light image, You will notice a bright blue star at the 12:00 position. Then below and left @ 11:00, there is a group of 3 stars. The star on the right of this small group has a lens flare that is traveling towards the southeast. The flare crosses a black area. That is the area in the image of the original post that appears to resemble a hole.

If you view the largest available image attached

http://ipac.jpl.nasa.gov/media_images/ssc2006-16c.jpg

and pan between the Visible image and the Infrared image you will notice that those bright blue stars now appear to be almost green and the black cloud is not visible with heat imaging so it must be cold dust.

Here is another great Orion image. It really shows what can only be seen with photography.

Martin · Post by **Martin** » Tue Aug 22, 2006 5:22 pm

I see it now -thank you for remembering the discussion and my request for more images.

How do these images compare to the original? I can't seem to match these up to the original posted image:

http://antwrp.gsfc.nasa.gov/apod/ap060221.html

I am navigationally lost!!!

BMAONE23 · Post by **BMAONE23** » Tue Aug 22, 2006 9:24 pm

I believe the original posted image:
http://antwrp.gsfc.nasa.gov/apod/ap060221.html
is oriented with a 90deg top to left rotation (counterclockwise).

The horsehead at the bottom middle has a small star below and left of it and another star left and slightly above it. The star that is left and slightly above the horsehead is the left most star in Orions belt. The brightest star above and left of the one by the horsehead is the center belt star. The area in question, on the right side of the original image, sits below the belt stars in the full image of Orion, in the knife.

does anybody know how this thread got 10503 views? I can't find what links here.

It keeps finding it's way back.

Martin · Post by **Martin** » Wed Aug 23, 2006 12:41 pm

Well, it has that many views because that’s how many people have viewed it.

Do you want to see the 2nd image that was passed on to me from Rick w/SSRO? I did dl to a host site but it has since expired. I suppose I could do it again if you would like to see it

BMAONE23 · Post by **BMAONE23** » Wed Aug 23, 2006 1:43 pm

Perhaps It's just popular imagry, or the counter might be off???

I think Orion is a popular attraction because it's easily recognizable in the night sky.

I like to see any image of the area that might capture more light than my eyes allow.
