Unprecedented Observations of Famous Black Hole

Post by Dragon Wed Jun 09, 2021 5:56 am

n April 2019, scientists released the first image of a black hole in the galaxy M87 using the Event Horizon Telescope (EHT).

However, that remarkable achievement was just the beginning of the science story to be told.

Data from 19 observatories are being released that promise to give unparalleled insight into this black hole and the system it powers, and to improve tests of Einstein’s General Theory of Relativity.

The Atacama Large Millimeter/submillimeter Array (ALMA) participated in the EHT observations in April 2017, and also produced an image of the larger scale jet emanated from the vicinity of the massive black hole.

Composite image showing how the M87 system looked, across the entire electromagnetic spectrum, during the Event Horizon Telescope’s April 2017 campaign to take the iconic first image of a black hole.

Requiring 19 different facilities on the Earth and in space, this image reveals the enormous scales spanned by the black hole and it forward-pointing jet, launched just outside the event horizon and spanning the entire galaxy.　

The upper left of the figure is an image taken by ALMA, showing the larger-scale jet observed on the same scale as the visible image taken by the Hubble Space Telescope and the X-ray image by Chandra (upper right).
