Explanation:
There's  
a black hole  
at the center of the Milky Way.  
  
Stars are observed to orbit  
a very massive and  
compact  
object  
there known as Sgr A* (say "sadge-ay-star").  
  
But this just released radio image (inset) from planet Earth's  
Event  
Horizon Telescope is the  
first direct evidence of the Milky Way's central black hole.  
  
As predicted by Einstein's Theory of General Relativity,  
the four million solar mass black hole's strong gravity  
is bending light and creating a shadow-like dark central region  
surrounded by a bright ring-like structure.  
  
Supporting observations made by  
space-based telescopes and ground-based observatories  
provide a wider view of the galactic center's dynamic environment  
and an important  
context for the Event Horizon Telescope's black hole image.  
  
The main panel image  
shows the X-ray data from Chandra and infrared data from Hubble.  
  
While the main panel is about 7-light years across,  
the Event Horizon Telescope inset image itself spans a mere 10  
light-minutes  
at the center of our galaxy,  
some 27,000 light-years  
away.
