Summary

[edit]
Description
English: In the heart of the Virgo cluster of galaxies lies a giant- and in its heart lies a monster. This elliptical galaxy is larger than our galaxy as it is 120,000 light years in diameter. However, since it is spherical in volume astronomers estimate that this ball of stars weighs in at over 2 trillion solar masses (of sun-like stars!). In this image many small fuzzy balls surround the galaxy. Each of these is a globular cluster which contains hundreds of thousands of stars. And finally the seemingly innocuous spike emanating from the core of the galaxy is a luminous stream of accelerated gas (almost the speed of light) having been driven from a black hole in the heart of M87. There are many companion galaxies that orbit this overbearing galaxy.This image was taken as part of Advanced Observing Program (AOP) program at Kitt Peak Visitor Center during 2014.
