First-ever image of cool gas disk surrounding Milky Way's black hole
..., or shifted, to the “redder” portion of the spectrum; the blue color represents gas moving toward Earth, so the radio waves are slightly scrunched, or shifted, to the “bluer” portion of the spectrum. Image: ALMA (ESO/NAOJ/NRAO), E.M. Murchikova...
