Google Sky: Microwaves

I've just been having a quick play with this KML file for Google Sky. It's the data from the WMAP mission, put together so that it overlays the sky (although the "Earth, Sky, there's no difference" quirk does mean that it can also appear as a "skin" for the Earth — which looks kind of odd).

I'm finding that having that image overlaid on the sky, especially when I dial down the transparency, is really helpful in understanding what some of the "hot spots" (for want of a better phrase?) really are.

Have a look at the tarantula nebula between Dorado and Mensa.

Yup, that was one of those that had me going "oh, right, of course!"

Dave

you know what the hotspots really are ?? Does Andrew Jaffe know this ?

Is there a KML file for the microwave sky before the foreground is removed ? That would really make sense, as you can the Milky Way, Orion, Magellanic Clouds etc...

Sorry Andy, but I'm not sure I follow your comment.
