Messier 87 Image Credit: [3]NASA, ESA and the Hubble Heritage Team Explanation: Enormous elliptical galaxy [4]Messier 87 is about 50 million light-years away. Also known as NGC 4486, the giant galaxy holds trillions of stars compared to the mere billions of stars in our large spiral Milky Way. M87 reigns as the large central elliptical galaxy in the [5]Virgo galaxy cluster. An energetic jet from the giant galaxy's core is seen to stretch outward for about 5,000 light-years in this sharp optical and near-infrared [6]view from the Hubble Space Telescope. In fact, the cosmic blow torch is seen across the electromagnetic spectrum from [7]gamma-rays to radio wavelengths. Its [8]ultimate power source is M87's central, supermassive black hole. An image of this monster in the middle of M87 has been captured by [9]planet Earth's Event Horizon Telescope.
