NGC 7808
Galaxy in the constellation Cetus
NGC 7808 is a lenticular galaxy in the constellation of Cetus. Its velocity with respect to the cosmic microwave background is 8521 ± 24 km/s, which corresponds to a Hubble distance of 125.67 ± 8.80 Mpc (~410 million light-years). It was discovered by American astronomer Frank Muller in 1886.
NGC 7808 is an active Seyfert I galaxy.
One supernova has been observed in NGC 7808: SN 2023qnz (Type Ia, mag. 20.14) was discovered by Pan-STARRS on 22 August 2023.
01Star-forming ring
NGC 7808 contains an outer star-forming ring, observed in ultraviolet rays. According to a 2019 study, the star formation is only above one solar mass per year. It is expected to decrease over time. Nevertheless, star-forming rings like in NGC 7808 still contain enigmatic features and can help astronomers to learn more about the evolutionary processes taken by these galaxies.
