Processing Images – Supernova 1987A (Part 2 of 2)

Unfortunately the Hubble telescope was not operating when supernova 1987A exploded, however there are a number of interesting images taken of the supernova since 1990.

In processing the images of the supernova, we were limited by having only two exposures available for this particular shot. We decided to focus on the central region of the supernova which is where all the action is.

The remanents of supernova 1987A are seen as a star like object in the center …unfortunately this was not picked up in the completed image. The remenents are surrounded by a number of ring like structures and huge clouds of diffuse gas.

The core-collapse of SN 1987A should result in the formation of a neutron star however astronomers have not yet been able to detect it.

The picture below shows our completed image of the supernova. The image on the left of the picture shows the result of processing the exposures as shown in the last post. The image on the right is a further processed result removing the colors in the back ground stars left over from the two filters as well as removing streaks and other errors in the image.
