Description

This is a slightly enhanced image of a supermassive black hole in polarized light at the center of the Messier 87 (M87) galaxy.
The original image from the Event Horizon Telescope (EHT) is in public domain. The EHT project is supported by the U.S. National Science Foundation, and others.

With the EHT, astronomers have been able to measure polarized emission, a signature of magnetic fields, very close to the edge of a black hole.
The newly published polarized image is key to understanding how the magnetic field allows the black hole to gobble up matter and launch powerful jets. The bright jets of energy and matter that emerge from M87’s core and extend at least 5000 light-years from its center are one of the galaxy’s most mysterious and energetic features. Most matter lying close to the edge of a black hole falls in. However, some of the surrounding particles escape moments before capture and are blown far out into space in the form of jets.

The EHT is able to obtain detailed black hole images by creating a virtual Earth-sized telescope, composed of many individual telescopes – these are ALMA, APEX, the IRAM 30-meter Telescope, the IRAM NOEMA Observatory, the James Clerk Maxwell Telescope (JCMT), the Large Millimeter Telescope (LMT), the Submillimeter Array (SMA), the Submillimeter Telescope (SMT), the South Pole Telescope (SPT), the Kitt Peak Telescope, and the Greenland Telescope (GLT).
