Thu, 12 Nov 2009 18:50:47 +0000 http://www.galaxyzooblog.org/2008/01/11/whats-the-blue-stuff-below/#comment-12599 I would like to mention though. If this was just a mas of brilliant blue stars that weighs 10 of thousands of solar masses, wouldnt we see a some type of lensing effect. As well why would an object so massive have little to no effect upon the density wave of its "nearby" spiral galaxy. from the observations thus far it seems that this object has very little mass compared to its neighbor. Very strange. I suppose that this is a super dense, but not super massive, collection of gasses that is being ionized by its neighbor. I would like to mention though.

(blueblob2-1.jpg) on this web page is a line that is very similar to the "blue blob". This line is diagonal and "intersects" the very bright object also in the "top left" corner of the picture. This line is a little fainter than the "blue blob" Any idea what that is?

It's a crucial difference, distinguishing an object shining by starlight from an object dominated by emission lines like the Voorwerp. The moral of the story? Look for the specific shade of blue!

I've seen they're almost as common to find as mergers. 587726032234741807 is also a blue blob-thing, but it’s part of the same galaxy in the picture, right?

Well done for reasearching into it. Wow, its rather interesting isn’t it. Well done for reasearching into it.

Midway down in the left-hand frame, the bottom link under PhotoObj is "FITS". That link leads to a page which lets you click for individual filtered images (or the combined atlas images, which IIRC are stacked into a 3D FITS form). This gets you a fairly large chunk of the scan, with the original x,y axes at skew angles to RA and declination axes. (I was pleased to find that, for examples, DS9 will rebin during display to align them with coordinates if requested). You can get the individual FITS images in ugriz from the object explorer pages.
