NGC 3904 is an elliptical galaxy in the constellation Hydra.[1] It was observed both by astronomers William Herschel in 1791 and John Herschel in 1834, respectively.[7] The galaxy's radial velocity, relative to the cosmic microwave background is measured at around 1915 ± 25 km/s, corresponding to a Hubble distance of around 28.25 ± 2.02 MPC.[2]
Characteristics
NGC 3904 exhibits no detectable neutral hydrogen or radio emissions, indicating a lack of ongoing star formation. It also hosts a system of globular clusters with relatively lower metallicity and bluer colors than those in bigger elliptical galaxies.[8]
Supernova
One supernova has been observed within the galaxy NGC 3904:
