The highlight photo of the week is the spiral galaxy NGC 2903. This image was obtained with the help of

Both were installed on the telescope in 2002and 2009 respectively. Interestingly, Hubble had previously observed this particular galaxy before, in 2001 (in the photo below). But at that time neither ACS nor WFC3 had yet been installed on the telescope.
Photo of 2001
The 2021 image boasts morehigh resolution. As a result, the entire structure of NGC 2903 is more detailed than in the 2001 photograph. ACS and WFC2 together cover a wide range of ultraviolet, optical and infrared wavelengths. The 2001 image was taken using the Wide Field Planetary Camera (WFPC2), which operated on Hubble from 1993 to 2009.
