Number 67 (Story #3), February 12, 1992 by Phillip F. Schewe and Ben Stein INFRARED IMAGES OF THE GALACTIC CORE reveal more than two dozen compact sources of near-infrared radiation. The measurements, recorded by the New Technology Telescope (NTT) at the European Southern Observatory (ESO) at La Sill, Chile, also show an expanding bubble of gas centered about 3 arcseconds from Sgr A* (the galactic core). Like evidence at other wavelengths (e.g., radio and gamma), the infrared pictures are consistent with the existence of a massive black hole at the center of the Milky Way. (Nature, 6 Feb. 1992.)
