M31 seen at multiple wavelengths


I'm preparing short 6-hour lecture course on galaxy evolution. I thought it would be more interesting to show the popular multi-wavelength M31 data image as an animation, so here's a little gif. The positional matching of the data sets is just done by eye so it isn't very precise, but it's good enough.

I'll be making the course available online if and when time permits.

    M33 doesn't show in IR?? (I guess the image truncated...)

    You mean M110, the bright companion at the top of the image ? Yes, that's just image truncation.

    Rhys Taylor Whoops, silly me! Yes, M110. (It looked kind of spiral in the small animation, but of course M33 is much farther away on the sky.)
