NGC 3109 is a small barred Magellanic type spiral or irregular galaxy. It does not appear to possess a core. It appears to be interacting with the Antlia Dwarf and may be gravitationally bound with Sextans A and Sextans B. This group of four galaxies is …

NGC 3109 is a Barred Spiral Galaxy located in the constellation of Hydra in the equatorial region. NGC 3109's distance from Earth is 4,347,664.51 light years. NGC 3109 is called NGC 3109 in the New General Catalogue (NGC).

2025年2月28日 · This O5-type supergiant is the hottest and youngest star confirmed in NGC 3109 to date. Its age indicates that star formation in NGC 3109 occurred at least as recently as 2 Myr ago. These observations of hot, massive stars in NGC 3109 demonstrate the utility of near-ultraviolet photometry to select O-type stars in nearby dwarf galaxies and ...

NGC 3109 is a Barred Spiral Galaxy in the Hydra constellation. NGC 3109 is situated south of the celestial equator and, as such, it is more easily visible from the southern hemisphere. Given its visual magnitude of 10.04, NGC 3109 is visible with the help of a binocular with a 80mm aperture or a small telescope.
