"It is a strange and strange place, and it is very difficult for us to investigate because there is a lot of dust between us and that; we can see things with infrared and radio waves but not necessarily with optical light.
"Now we have stars that appear to have formed in the region and have escaped from them and, at 29,000 light years from Earth, are now close enough for us to study in relative detail.
"And it seems very normal, so it should tell us something about how stars form near the Galactic center and about the conditions there."
Sagittarius A * (read: one-star) is a supermassive black hole located approximately 26,000 light years or 152,844,260,000,000,000 miles from our planet.
The terrible gravity well is estimated to weigh about four million times more than our Sun.
