ESA today released the first all sky images from Planck. The first all sky survey was completed a few months ago, but it’s taken some time to get things processed to the stage where we can release images. So here it is – Planck’s first view of the whole sky!
The image is dominated by the dust in our own galaxy, seen in blue, but in the top left and bottom right you can see a more mottled structure which is the cosmic microwave background. The next all sky survey, currently being observed, and a lot of processing are needed to remove the foreground galactic emission and the emission of intervening galaxies and galaxy clusters before we can get a clear picture of the microwave background. That’s the point at which we will be able to see the exciting new results on cosmology that will come from Planck.
There’s a lot more to come as well, as this image shows, with information on our own galaxy and others. This overlay shows some more information about what we’re seeing and highlights well known objects and parts of the sky, as well as images already released from Planck.
