M87 is a well-known radio galaxy located in the Virgo cluster of galaxies, approximately 55 million light-years away from Earth. It is one of the largest and brightest galaxies in the observable universe, known for its massive black hole at its center, which is one of the most studied black holes in astrophysics. Research on M87 focuses on studying the properties of its black hole, including its accretion disk, jets of high-energy particles, and the origins of its powerful radio emissions. Scientists also study the galaxy's structure, formation, and interactions with its surrounding environment to better understand the evolution of galaxies and the role of black holes in shaping the universe.
