Black Hole Hunters | Out There | The New York Times        The New York Times        13 June 2015

 

Astronomers hope the Event Horizon Telescope,

a synchronized network of radio antennas as large as the Earth,

will take the first ever picture of a black hole,

an abyss so deep no light can escape.

Dennis Overbye, Jonathan Corum and Jason Drakeford

An illustration of the supermassive black hole

located in the middle of the very dense galaxy M60-UCD1.

 

It weighs as much as 21 million times the mass of our Sun.

 

Lying about 50 million light-years away,

M60-UCD1 is a tiny galaxy with a diameter of 300 light-years

just 1/500th of the diameter of the Milky Way!

 

Despite its size it is pretty crowded,

containing some 140 million stars.

 

Because no light can escape from the black hole,

it appears simply in silhouette against the starry background.

 

The black holes intense gravitational field

warps the light of the background stars

to form ring-like images just outside the dark edges

of the black holes event horizon.

 

(Combined observations by the NASA/ESA Hubble Space Telescope

and NASAs Gemini North telescope determined the presence

of the black hole inside M60-UCD1.)
