Discovered in 1781 by Charles Messier
Messier 87 is a supergiant elliptical galaxy located in the constellation Virgo approximately 53 million light-years from the Earth. M87 is one of the most massive galaxies in the observable universe. The galaxy has an active supermassive black hole in its central core. A jet of energetic plasma, powered by the massive black hole, is being ejected from the core at relativistic speed. This jet extends at least 4,900 light-years and is one of the brightest radio sources in the sky. In the image above, the jet can be seen extending from the bright core at its 1 o'clock position. M87's black hole has been imaged by the Event Horizon Telescope and a final processed image was released on April 10, 2019.
