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