    What's going on? This is not the galaxy being displayed in SkyServer! Totally different shape and color!

    This is the same galaxy as I see in SkyServer. The colors will look very different, since this is an infrared image (from UKIDSS) and the SkyServer shows the optical image from SDSS. The orientation for the two images is flipped right-to-left, but you can see the same bright star in both images.

    We also expect the shape to change for some galaxies (for example, bars might appear where you didn't see any before). That's precisely the reason we're classifying these infrared images - to measure how morphology changes between optical and infrared wavelengths!
