IRAS image of Saturn

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…/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.

    thats a nice but obviously false statement about this “image of saturn”, there are clearly 2 distanct objects emitting their own light plus the ring of other debrie is clearly not in the right position for an image of saturn by other of nasa’s own images of saturn. it is of grave concern to me for the blaitent disinformation that the nasa CORPORATION to annouce certain findings and then in same breath discount them or claim no proof or evidence of excistance. ALL WE WANT IS TOTAL TRANSPARENY AND THE TRUTH OF ALL THINGS NASA REALLY KNOWS. thank you for and if this is read and it would be apprieciated if an honest and respectful response would be sent.

    There are two images in the original IRAS data because IRAS scanned the sky twice in this region. Saturn moved a bit between the two scans. These two scans were added together to create the original IRAS survey images. As I recall the scans were a few weeks apart. If you go to the underlying HCON data (available at IRSA) you can get the scans separately. The hope for the IRAS mission was to complete three scans of the entire sky and this was achieved over most of the sky, but not everywhere.

    So where can we view the artifact that was removed from the IRIS 100 scan? Bueller….Bueller…..Anyone……

    The artifact is the area of the image (at the top of the blog article) where saturn appears in the field of view. It was removed to make the image more relevant to the study of infrared data beyond the solar system.

    Horse shit. NASA = Never A Straight Answer. Mother fucking liars as are all who are part of the government. You will never hear the truth from them. This is why you need to find it on your own. Saturn…LMAO.

    I’m still amazed by NASA’s patience to answer these fanatics,like, he has more important things to do, like figuring out how to make Mars habitable
