NASA explains that this particular image was made using observations from eight different infrared filters spread across two of Hubble’s more advanced astronomical instruments: the Advanced Camera for Surveys and the Wide Field Camera 3.“During SM4, two new scientific instruments were installed — the Cosmic Origins Spectrograph (COS) and Wide Field Camera 3 (WFC3),” NASA explains.The Advanced Camera for Surveys was installed on Servicing Mission 3B, but was considered a “failed instrument.” This was repaired during Servicing Mission 4.“Two failed instruments, the Space Telescope Imaging Spectrograph (STIS) and the Advanced Camera for Surveys (ACS), were revived by the first-ever on-orbit repairs,” NASA continues.
