Their population density decreases with increasing distance from the core. It has an active supermassive black hole at its core, which forms the primary component of an active galactic nucleus. The black hole was imaged using data collected in 2017 by the Event Horizon Telescope (EHT), with a final, processed image released on 10 April 2019. [13]

- Supermassive black hole
Black holes are a class of astronomical objects that have undergone gravitational collapse, leaving behind spheroidal regions of space from which nothing can escape, including light. Observational evidence indicates that almost every large galaxy has a supermassive black hole at its center.
The supermassive black hole at the core of Messier 87, here shown by an image by the Event Horizon Telescope, is among the black holes in this list. This is an ordered list of the most massive black holes so far discovered (and probable candidates), measured in units of solar masses (M ☉), approximately 2 × 10 30 kilograms.
The elliptical galaxy M87 is the home of several trillion stars, a supermassive black hole and a family of roughly 15,000 globular star clusters. For comparison, our Milky Way galaxy contains only a few hundred billion stars and about 150 globular clusters.
4 Οκτ 2024 · M87, giant elliptical galaxy in the constellation Virgo whose nucleus contains a black hole, the first ever to be directly imaged. M87 is the most powerful known source of radio energy among the thousands of galactic systems constituting the so-called Virgo Cluster.
10 Απρ 2019 · The supermassive black hole imaged by the EHT is located in the center of the elliptical galaxy M87, located about 55 million light years from Earth. This image was captured by FORS2 on ESO's Very Large Telescope.
10 Απρ 2019 · In April 2019, scientists released the first image of a black hole in the galaxy M87 using the Event Horizon Telescope (EHT). However, that remarkable achievement was just the beginning of the science story to be told.
