Full-Sky Temperature Maps in Google Earth

Microwave Sky in Google EarthMicrowave Sky in Google Earth

Five more Universe temperature maps from NASA’a  Wilkinson Microwave Anisotropy Probe (WMAP), covering different frequency bands.

These were used by the WMAP team to subtract the galactic signal and produce the Cosmic Microwave Background map.  The wide red band across the centre of each is the microwave emission from our galaxy.

Created using the same technique as the CMBR file these are viewable in Google Earth from the outside and inside.  Jpeg compressing these maps is next to impossible without introducing a bundle of artifacts, so the file is kind of on the large side.

On a related note:  Google launched their NASA collaboration last week with some new default layers Google Earth –  under ‘Featured Content’. If you haven’t checked it out already, do so. 🙂 The ‘Earth City Lights’ views are impressive – very cool how it’s possible to make out features like coastlines, river, roads and even the Trans-Siberian railway. But don’t miss the amazing overlays in the Satellite Imagery section – you need to click on the links in the description text of the blue placemarks to get these to appear.

    Hi

    I have a little correction for your map:

    The milkyway is not sitting around the equator!

    You can see the milkyway in the default mode, with the galactic center around the spot where “User’s Guide to galaxies: The Milkey Way” is, running from northe-west to south-east.

    Your images has to be offset and rotatet to align with that.

    I hope you can use the advise
