four globular clusters in fornax.


ngc 1049 globular cluster 500,000 light-years earth. in fornax dwarf galaxy. ngc 1360 planetary nebula in fornax magnitude of approximately 9.0, 978 light-years earth. central star of magnitude 11.4, unusually bright specimen. 5 times size of famed ring nebula in lyra @ 6.5 arcminutes. unlike ring nebula, ngc 1360 elliptical.


the fornax dwarf galaxy dwarf galaxy part of local group of galaxies. not visible in amateur telescopes, despite relatively small distance of 500,000 light-years.



the hubble ultra deep field seen muse.


ngc 1097 barred spiral galaxy in fornax, 60 million light-years earth. @ magnitude 9, visible in medium amateur telescopes. notable seyfert galaxy strong spectral emissions indicating ionized gases , central supermassive black hole.


ngc 1365 barred spiral galaxy located @ distance of 60 million light-years earth. ngc 1097, seyfert galaxy. bar center of star formation , shows extensions of spiral arms dust lanes. bright nucleus indicates presence of active galactic nucleus - galaxy supermassive black hole @ center, accreting matter bar. 10th magnitude galaxy associated fornax cluster.


fornax radio galaxy extensive radio lobes corresponds optical galaxy ngc 1316, 9th-magnitude galaxy. 1 of closer active galaxies earth @ distance of 80 million light-years, fornax appears in optical spectrum large elliptical galaxy dust lanes near core. these dust lanes have caused astronomers discern merged small spiral galaxy. because has high rate of type ia supernovae, ngc 1316 has been used determine size of universe. jets producing radio lobes not particularly powerful, giving lobes more diffuse, knotted structure due interactions intergalactic medium. associated peculiar galaxy entire cluster of galaxies.


fornax has been target of investigations furthest reaches of universe. hubble ultra deep field located within fornax, , fornax cluster, small cluster of galaxies, lies within fornax. @ meeting of royal astronomical society in britain, team university of queensland described 40 unknown dwarf galaxies in constellation; follow-up observations hubble space telescope , european southern observatory s large telescope revealed ultra compact dwarfs smaller known dwarf galaxies, 120 light-years (37 pc) across.


udfj-39546284 candidate protogalaxy located in fornax, although recent analyses have suggested lower redshift source.
