Black Hole

The Virgo black hole resides 55 million light-years from Earth and has a mass 6.5 billion times that of the Sun.

The task of capturing the black hole in the center of the Milky Way lies ahead for the Event Horizon Telescope (EHT).

Centre of the Milky Way

A technology called very-long-baseline interferometry allows the EHT to achieve an angular resolution of 20 micro-arcseconds — enough to read a newspaper in New York from a sidewalk café in Paris.
