Answer to Question 140

A140: The Galactic Center is the rotational center of the Milky Way galaxy. It is located at a distance of 8.33±0.35 kpc (~27,000±1,000 ly) from the Earth in the direction of the constellations Sagittarius,Ophiuchus, and Scorpius where the Milky Way appears brightest. There is strong evidence that supports the existence of asupermassive black hole at the Galactic Center of the Milky Way.

The Galactic Centre as seen by one of the 2MASS infrared telescopes, is located in the bright upper left portion of the image.
