Telescopes Unite in Unprecedented Observations of Famous Black Hole

Very recommendable! Amazing stuff! An amazing, coordinated global effort!

"... The NASA telescopes involved in this observing campaign included the Chandra X-ray Observatory, Hubble Space Telescope, Neil Gehrels Swift Observatory, the Nuclear Spectroscopic Telescope Array (NuSTAR), and the Fermi Gamma-ray Space Telescope. ...
The sequence begins with the EHT [Event Horizon Telescope] image of the black hole in M87 released in April 2019 (the data was obtained in April 2017). It then moves through images from other radio telescope arrays from around the globe, moving outward in the field of view during each step. ... Next, the view changes to telescopes that detect visible light (Hubble and Swift), ultraviolet light (Swift), and X-rays (Chandra and NuSTAR). .."

Telescopes Unite in Unprecedented Observations of Famous Black Hole Some of the world’s most powerful telescopes simultaneously observed the supermassive black hole in galaxy M87, the first black hole to be directly imaged.
