NGC 1515 ist eine Balken-Spiralgalaxie vom Hubble-Typ SBbc im Sternbild Dorado am Südsternhimmel. Sie ist schätzungsweise 45 Millionen Lichtjahre von der Milchstraße entfernt und hat einen Durchmesser von etwa 135.000 Lichtjahren.

Im selben Himmelsareal befinden sich unter anderem die Galaxien PGC 14350, PGC 14406, PGC 14523, PGC 421833.[4]

Das Objekt wurde am 23. Dezember 1837 von John Herschel entdeckt.[5]

A Collection of Spirals

At the center of this image is NGC 1515, an intermediate barred spiral galaxy that is part of the Dorado Group. Large-scale observations of the Universe have found that galaxies “clump” together. These clumps are held together by a loose gravitational pull and designated a group or cluster, depending on the number of galaxies within a bounded radius. One of the characteristics of groups of galaxies is the slow speed of individual galaxies, about 150 km/s (93 mi/hr), which results in frequent interactions between members. The Dorado Group is composed of three subgroups and NGC 1515 is a member of the subgroup associated with the galaxy NGC 1566. In the background of this image are thousands of other galaxies, located even further away than NGC 1515, alongside stars located in our own Milky Way.

This image is composed of data taken with the Dark Energy Camera on the Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory (CTIO), a Program of NSF’s NOIRLab, as part of the Dark Energy Survey, a project that mapped millions of galaxies. One of the most powerful digital cameras in the world, the Dark Energy Camera was designed specifically for the Dark Energy Survey and was operated by the US Department of Energy and NSF between 2013 and 2019.
