There are two galaxies I can’t seem to find the catalog IDs and numbers for, and it’s making me buggy (or buggier).
The first is the Cartwheel Galaxy, in the Sculptor constellation. It can be seen on a number of Astronomy Picture of the Day pages, including the one for January 18, 2006. Since some of the photos are from the Anglo-Australian Observatory, I assume that only southern hemisphere earth-based telescopes can “see” it. Please, what catalog and number??
The second is one identified as the Integral Galaxy. The photo is from a group apparently taken by an amateur at the Kitt Peak Visitor Center, which means it’s at least visible in some parts of the northern hemisphere. It’s from their Image Gallery. I would also like - very much - to find not just the catalog ID, but also a better (i.e., higher resolution) photo of it.
Thanks ever so much! I will bookmark those links and comment them, so I can find them next time.
Um, Angua, I know I said photo when I should have said image, given that most telescopes these days are CCDs, or even more exotic instruments, and most of the purty pitchers are both composites and image-processed. I always search the APOD site (which preferentially gives HST or HHS links), before looking elsewhere. And did a separate search on both the Hubble and NASA sites. I’ll admit I should have gone to both the AAO and ESO sites and searched them. I know better, if I’d thought, but last time I went to the ESO site, it wasn’t set up with purty-pitcher-lovers in mind. Mea culpa.
Yeah, I figured that you probably did want a composite, and knew that it was a composite, but I figured I may as well make sure (doing public outreach, I end up spelling everything out). Sorry if I ended up sounding as if I was patronizing you.
Incidentally, I did do a search on the other image archives, including NASA Extragalactic Database (NED), and there wasn’t much there for the 2nd galaxy. There is the option on NED to search by name, including common names such as Cartwheel Galaxy.
Apologies for the double post, but I did just realise that the link I linked to above may not be your best bet for pretty pictures, but will give you further information on an object. The Chandra webpage also has very pretty pictures of galaxies (but I realise that you may already have checked there, in which case, ignore me. ;))
Sure. No problem. You have no way of knowing what links I know about, or have saved.
I will try it with the next astronomical image problem I have. Hopefully, it will provide the answers.
Of course there’s always the galaxy I recall seeing one image of in an ad in SciAm 20 or more years ago, and have never been able to get ID’d. It’s not quite edge-on, but it has some similarity to the Integral, in that it appears to be flipping over (with edges trailing). I even asked an astronomy prof in Alabama about it a few years ago, and he hadn’t a clue.
