This spectacular luminescent image from the Hubble Location Telescope parts multiple galaxies, maybe most noticeably LEDA 58109, the lone galaxy in the easier correct. LEDA 58109 is flanked by two further galactic objects to its decrease left — an brisk galactic nucleus (AGN) known as SDSS J162558.14+435746.4 that partially obscures the galaxy SDSS J162557.25+435743.5, which appears to be like to be to slump out to the correct at the reduction of the AGN.
Every so often galaxy classification is supplied as one thing of a dichotomy: spiral and elliptical. Nonetheless, the numerous diversity of galaxies on this image alone highlights the advanced internet of galaxy classifications that exist. This consists of galaxies that residence extremely fascinating AGNs at their cores and galaxies whose unfamiliar shapes defy the classification of either spiral or elliptical.
This collection of galaxies additionally illustrates the mountainous vary of names that galaxies have: some that are slightly immediate, luxuriate in LEDA 58109, and a few that are very prolonged and necessary to identify in thoughts, such because the two galaxies to the left. That is on story of there are multiple cataloging systems that chart the celestial objects in the evening sky.
No person catalog is total, and they quilt overlapping regions of the sky, so many galaxies belong to quite a bit of diversified catalogs. As an illustration, the galaxy on the correct is LEDA 58109 in the LEDA galaxy database, but is on the total is called MCG+07-34-030 in the MCG galaxy catalog, and SDSS J162551.50+435747.5 in the SDSS galaxy catalog — the identical catalog that additionally lists the two galaxies to the left.
