NGC 5468

NGC 5468 is a barred spiral galaxy located approximately 130 million light-years away in the constellation Virgo. It is classified as type SBc, indicating a barred spiral structure with loosely wound spiral arms.

NGC 5468 is noted for its high rate of supernova activity. It has hosted several observed supernovae since the late 20th century, including SN 1999cp, SN 2002cr, SN 2002ed, SN 2005cz, and SN 2018dfg. This prolific supernova production makes it a subject of interest for astronomers studying stellar evolution and the rates of star formation and death within galaxies.

The galaxy is part of the Virgo III Groups, a collection of galaxies loosely associated with the larger Virgo Supercluster, though it is located somewhat further away. Its redshift and distance measurements suggest that it is receding from us as a result of the expansion of the universe.

Studies of NGC 5468 have focused on its morphology, star formation regions, and the properties of its interstellar medium, in addition to the analysis of the supernovae events. The presence of a bar structure is thought to influence the gas dynamics within the galaxy, channeling material towards the central regions and potentially triggering star formation. Further research aims to understand the reasons behind its unusually high supernova rate and the processes driving its evolution.
