Hello All
http://hubblesite.org/newscenter/newsde ... s/2006/24/
Its amazing how the structure of this galaxy is on a disc. The garvitational forces from the black hole create the accretion disk and forms the galaxy.
And
Its omly 44 million light years away. A skip and a jump.

please click on photo for 12 June to get highest resolution photo.
I am stunned by the thousands of galaxies that lie beyond this subject.
also note that in the text nothing was mentioned about the HUGE Halo of stars lieing outside of the galactic plane of subject galaxy. very impressive photo and another Kudos to HST,NASA and ESA.
my question is
which cluster or supercluster is imaged behind NGC5866?

Lenticular galaxies aren't supposed to be photogenic. Like spiral galaxies, they contain a disk, but like elliptical galaxies, they are usually short on dust, gas, and pretty spiral arms. Lenticulars are relatively little studied, possibly because of their seemingly benign nature. Famous galaxies historically classified as lenticular include M84, M85, and M86

Tightly wound, almost concentric, arms of dark dust encircle the bright nucleus of the galaxy NGC 2787 in this Hubble Space Telescope image. In astronomer Edwin Hubble's galaxy classification scheme, NGC 2787 is classified as an SB0, a barred lenticular galaxy. These lens-shaped galaxies show little or no evidence of the grand spiral arms that occur in their more photogenic cousins, though NGC 2787 does sport a faint bar, not apparent in the Hubble image, but visible in the ground-based image below.

If the blue disc in the galactic plane comprises young stars, presumably the brightness seen extending many times the thickness of the central dust lanes & perpendicular to the galactic plane arises from other stars in NGC5866 unresolved in this photograph. The 60 000 light year dimension (incorrectly described as a time in the APOD text) would thus extend well beyond the edges of the photograph.

I was delighted by the June12/06 image of Edge-On Galaxy NGC 5866l, as galaxies are my favourite heavenly bodies. Yet it seems a trifle sad that Charles Messier stuck to dry numbers to identify these spectacular wonders when the whole realm of mythology and poetry was available to him.
What is the procedure for naming astronomical objects? It would make my millennium if I could bestow on this extraordinary stellar conglomerate the name "Cosmic Hairy Caterpiller".

What is the name of the distant galaxy in the upper left-hand quadrant of the picture. This is the first time I've ever posted anything, and I don't know if I'm doing it correctly.

An excellent name

I don't know the name of that galaxy - apologies - but the picture is amazing, isn't it?
Perhaps someone that knows what that galaxy's title/designation is will come along and enlighten us! (I'm not at home, or I'd try checking my Starry Night program.)
Oh and welcome to the NSL boards!

Don't know but given that it looks like a giant red "S", I would say it is the galaxy where you would find Krypton.

I'm guessing that's NGC 5866A (aka Turn 121A or Keeler 690), but that's just a guess on my part. Being a non-astronomer, it's hard to make heads or tails of all the astronomical data.
