NGC 5495, which is located roughly 300 million light-years from Earth in the constellation Hydra, is a Seyfert galaxy, a type of galaxy with a
Astronomers studying supermassive black holes lurking in the hearts of other galaxies captured a series of observations, including this image. Investigating the central regions of galaxies can be especially challenging: as well as the light created by matter falling into supermassive black holes, areas of star formation, and the light from existing stars all contribute to the brightness of galactic cores.
Thanks to Hubble’s crystal-clear vision, astronomers were able to disentangle the various sources of light at the core of NGC 5495. This allowed them to weigh its supermassiveBesides for NGC 5495, two stellar interlopers are visible in this image. One is just outside the center of NGC 5495, and the other is very prominent alongside the galaxy.
