DASI Collaboration, 2002
JPEG file, 2407x2000 pixels (33.43x27.78 inches) @ 72.00 pixels/inch
An image of the intensity and polarization of the cosmic microwave background radiation made with the Degree Angular Scale Interferometer (DASI) telescope. The small temperature variations of the cosmic microwave background are shown in false color, with yellow hot and red cold. The polarization at each spot in the image is shown by a black line. The length of the line shows the strength of the polarization and the orientation of the line indicates the direction in which the radiation is polarized. The size of the white spot in the lower left corner approximates the angular resolution of the DASI polarization observations.
