We have had a lot of interest in images centered on coordinates 13h 45m 18.2s, -08d 13m 07s recently. SkyView images of this area in the sky using the Infrared Astronomical Satellite (IRAS) survey are often added to the SkyView Image Gallery and we are asked about the unusual artifacts.
It turns out that this image is a sum of observation images taken by the Infrared Astronomical Satellite (IRAS) at times when the planet Saturn was in its field of view. The smearing affect is due to the timing of the different observations that make up the final image.
This artifact was removed in the subsequent IRIS 100: Improved Reprocessing of the IRAS Survey: 100.
There are more of the same image with nice color manipulations at our SkyView Image Gallery at http://skyview.gsfc.nasa.gov/userim…/index/2014-06-15_2.html (scroll down)
Further information: ISSA Explanatory Supplement – the table at the bottom of the page lists the coordinates of IRAS images affected by planets.
