Just for fun: an impossible matching of a tiny crop of
my RGB image vs the infrared JWST Stephan's Quintet mosaic picture (Source:
NASA, STScI, and ESA/CSA).Together, the five galaxies of Stephan’s Quintet are also known as the Hickson Compact Group 92 (HCG 92).
Although called a “quintet,” only four of the galaxies are truly close together and caught up in a cosmic dance. The fifth and lower galaxy, NGC 7320, is closer then the other four. NGC 7320 resides 40 million light-years from Earth, while the other four galaxies (NGC 7319, NGC 7318B, NGC 7318A, and NGC 7317), collectively designated as Arp 319, are about 290 million light-years away. This is still fairly close in cosmic terms, compared with more distant galaxies billions of light-years away, that can be seen in the background of the JWST image.
The JWST picture is an enormous mosaic, that contains over 150 million pixels and is constructed from almost 1,000 separate image files. The visual grouping of five galaxies was captured by Webb’s Near-Infrared Camera (NIRCam) on 11 June 2022 and Mid-Infrared Instrument (MIRI) on 11-12 June, 1 July 2022.
My image was recorded on the night of 29th August from my terrace in Vienna (Austria) under Bortle 7 sky.
