This luminescent picture options a number of galaxies, maybe most noticeably LEDA 58109, the lone galaxy within the higher proper. LEDA 58109 is flanked by two additional galactic objects to its decrease left—a galaxy with an lively galactic nucleus (AGN) referred to as SDSS J162558.14+435746.4 that partially obscures the galaxy SDSS J162557.25+435743.5, which seems to poke out to the appropriate behind the AGN.
Galaxy classification is usually offered as one thing of a dichotomy: spiral and elliptical. However, the variety of galaxies on this picture alone highlights the complicated internet of galaxy classifications that exist, together with galaxies that home extraordinarily luminous AGNs at their cores, and galaxies whose shapes defy the classification of both spiral or elliptical.
The pattern of galaxies right here additionally illustrates the wide range of names that galaxies have: some comparatively brief, like LEDA 58109, and a few very lengthy and difficult to recollect, equivalent to the 2 galaxies to the left. This is because of the number of cataloging programs that chart the celestial objects within the night time sky. No one catalog is exhaustive, they usually cowl overlapping areas of the sky in order that many galaxies belong to a number of completely different catalogs. For instance, the galaxy on the appropriate is LEDA 58109 within the LEDA galaxy database, however is also called MCG+07-34-030 within the MCG galaxy catalog and SDSS J162551.50+435747.5 within the SDSS galaxy catalog—the identical catalog that additionally lists the 2 galaxies to the left.
