solar radio light
Which of the following is NOT part of the chain of evidence that leads many astronomers????
Which of the following is NOT part of the chain of evidence that leads many astronomers suspect that there is a black hole in the center of the Milky Way? a. The fact that Sagittarius A is a fixed radio source, while objects around him seem to be b. the proposal in the Hubble Space Telescope has shown us a visible light image of an accretion disk in the center of the observation c. The Galaxy that matter in the central region continues to be falling in moving toward the center of stars d.the about 5 days of light from the center indicates a mass of 2.6 million solar masses inside their orbits e.The existence of a strong radio source at the center, whose size appears to be no larger than the orbit Jupiter
C was originally going to say, but I thought about it. Perhaps it is a trick question (?) The answer (I think) is B. I do not think there is a visible image light from the accretion disk in the center of the galaxy, the center is obscured by gas and dust clouds, so do not think I could have a visible light image. Infrared ultraviolet, X rays, gamma rays, radio waves, so certainly (those not significantly blocked by dust and gas), but not visible light.
