Wow, that was presented on the 11th. How do you find the time to keep abreast? I guess I wasn't imagining after all. I was seeing what they are seeing. I haven't thoroughly read the complete pdf presentation yet as I just got back on the net. I am hoping there is a hint at what is causing that corkscrew spiral emanating from the toroid hole. I am truly amazed at the strides we have made at imaging. Yea for NICMOS. I am so thankful the Hubble upgrade was so successful. Just think, a couple years ago they were considering letting her die.

Definitely check out the paper as to the location of Sgr A* as seen with Hubble :) wjwbudro, although I haven't had the time to fully read it, a paper recently appeared on the arXiv site (http://arxiv.org/abs/0911.2226) concerning Hubble's NICMOS Paschen-alpha survey of the Galactic Center.

Wow; it's amazing that they've been plotting these close-in objects for 15 years. Now if only those object designators could be superimpose onto this image. i.e. is Sgr A* (the presumed center/BH) inside what looks to be the donut hole of the "brighter" toroid/sphere in this image?

I did recall and revisited the UT blog "Near Sighted No More" April 29. X-rays generated by a young star burst nursery around Sag-A however, that "brighter" spherical concentration peeked my curiosity esp. that dark area and jet within the toroid. Btw, is anyone really certain as to the exact location of our elusive black hole? I was certain I found it. lol I won't let the door slam my behind as I exit. Thanks guys.

More than likely it's a build-up of hot gas in the region (maybe increased star formation in that area?) Can someone more knowledgeable than I make out what that bright spot is? wjwbudro: I doubt that's our black hole per se because it's not very active right now.

Can I assume that all of this white region is the x-ray activity produced by the black hole? By enlarging the image via windows picture and fax viewer, I can make out what seems to be a "brighter" spherical white area with jets streaming from it looking somewhat like a tilted 5 point star. The jet (at about 1'oclock) looks to be "corkscrewing" out from a darker region in the "toroidal looking" sphere. Wished I knew what I was seeing (imagining?) You have to sit back and relax your eyes a bit to see it. @Nancy "Note that the center of the galaxy is located within the bright white region to the right of and just below the middle of the image."

Amazing Image, I do sometimes wonder however how much this is art, The telescopes collect data in wavelengths beyond the capabilities of our sight, this data is then expressed and recombined into these images.

We would probably never see this with our own eyes, Its interesting how we are using technology to transcend our biological limitations with astronomy.

And the Paschen-alpha 'vortex' nebula around Sgr A-star really stands out.
