black hole and the distance between our sun and the
galactic center, roughly 26,000 light - years away.
This fuzzy warmth from the
galactic center has puzzled scientists for 30 years and clearer observation of it has led Ghez and her collaborators to conclude that it is most likely superheated interstellar dust on the verge of falling into the

According to a popular scenario explaining the formation and evolution of galaxies and supermassive
black holes, radiation from
galactic centers — where supermassive
black holes locate — can significantly influence the molecular gas (such as CO) and the star formation activities of the galaxies.

A widely accepted idea has described this phenomenon as: the strong radiation from the
galactic center in which the supermassive
black hole locates ionizes (* 1) the surrounding gas and affects even molecular gas that is the ingredient of star formation; the strong radiation activates (* 2) or suppresses (* 3) the star formation of galaxies.
