Astronomers have observed a supermassive black hole at the center of Messier 87 (M87) launching a powerful jet from its event horizon into space for the first time. The data collected, using the Global Millimetre VLBI Array (GMVA), the Atacama Large Millimeter/submillimeter Array (ALMA) and the Greenland Telescope (GLT), will help better understand how black hole jets are created.
The supermassive black hole at the center of M87 is 6.5-billion times larger than the Sun, and this new image shows the connection between the base of the jet as well as the matter swirling around it. Matter heats up and releases radiation in wavelengths of light as it orbits around the black hole, thus creating ring structures seen glowing around M87’s shadow.

We know that jets are ejected from the region surrounding black holes, but we still do not fully understand how this actually happens. To study this directly we need to observe the origin of the jet as close as possible to the black hole,” said Dr Ru-Sen Lu, the lead author of the Shanghai Astronomical Observatory.
