Andromeda Galaxy (infrared)

edit
 
Original - Andromeda Galaxy in infrared, by the Spitzer space telescope. The Andromeda Galaxy is a spiral galaxy 2.5 million light-years away in the constellation Andromeda, making it the nearest spiral galaxy to the Milky Way. The exposure time of this image was 100 sec/pixel, and its scale is 2.8 x 0.8 degrees.
Reason
High res, great quality. Enormous EV, this is one of the best known galaxies in the universe, at least to us. Definitely the best quality image we have of it from the project.

  • Support high rez The one MER-C linked to above.--HereToHelp (talk to me) 18:51, 6 December 2008 (UTC)[reply]
  • Support high rez: Plenty of EV. But for me, the wow factor is lacking, i'd prefer a regular colour picture. (Striked because people mistook what I meant. (it was worded poorly) – Jerryteps 08:21, 7 December 2008 (UTC)[reply]
    • Infrared by definition doesn't have a visible colour, so I guess what you are really saying is that you'd prefer a real-colour image of the galaxy rather than infrared, but the actual information gained from it would be completely different and not comparable.

      • I think you misunderstood what I was saying (It was worded poorly). It's that in my opinion, the infrared picture does not have as much visual appeal as a real colour picture would. But the picture has information that a real colour picture could never capture, it's that i'm taking a few "points" off because an infrared picture does not have the same visual appeal in my opinion as a real colour picture does. I shouldn't really of mentioned because it's not really that relevant since i'm still supporting and nothing could be done to fix it without loosing current detail. – Jerryteps 23:46, 8 December 2008 (UTC)[reply]
  • (edit conflict) Conditional support and comment You cannot get a "regular color picture" of this - it is an image of one single wavelength of infrared (24 micron)! This is a dramatic contrast to the traditional view at visible wavelengths, as the source page states. This info must be in the caption for me to support (only the hi-res version) ! --Janke | Talk 09:01, 7 December 2008 (UTC)[reply]
  • Comment I was about to upload the high rez to a new file name when I realized it's about 21MB, whereas the halfsize is about 1KB. I expected it to be bigger, but not by four orders of magnitude. Can someone explain this discrepancy? (And upload a possibly compressed version of the hi rez to Commons?)--HereToHelp (talk to me) 13:01, 7 December 2008 (UTC)[reply]
1,014 KB means 1.014 MB. Some countries use commas as thousands separator, others as decimal point. So, it's only 2 times 1 order of magnitude... --Janke | Talk 13:20, 7 December 2008 (UTC)[reply]
Ah, that makes more sense. (Even so, 20x the size for about 4x or 5x the area?) Oh well.--HereToHelp (talk to me) 15:10, 7 December 2008 (UTC)[reply]
