Which statement about Sgr A* is not true?

The statement regarding Sgr A* being the brightest source of visible light in the direction of the galactic center is not true. Sgr A*, which is the supermassive black hole located at the center of our Milky Way galaxy, is primarily known for its strong emission in the radio and X-ray wavelengths rather than in the visible spectrum.

While visible light observations of the region around Sgr A* can reveal various stars and other astronomical phenomena, Sgr A* itself is not the brightest object in the visible range. This is primarily due to the significant amounts of interstellar dust that obscure a direct line of sight to the galactic center in visible wavelengths. As a result, when considering the overall brightness in visible light within that part of the galaxy, other stars and celestial objects outshine Sgr A*.

In contrast, Sgr A* is known for its strong emissions in other wavelengths, confirming its nature as a supermassive black hole and making it a focal point of astronomical research—particularly in radio and X-rays. These characteristics distinguish Sgr A* from other celestial sources and reinforce our understanding of black holes and the dynamics of galactic centers.
