EurekAlert has various items from Chandra this week. Two look faintly like
they might excite Robert Bradbury: both the Milky Way's and Andromeda's
core superholes look too faint or small. Maybe they're being used/cloaked
by M-Brains. (But if so, why not use the lot?)

            Chandra finds a 'cool'
            black hole at the heart of
            the Andromeda Galaxy
            In its first look at the Andromeda
            Galaxy (M31), NASA's Chandra
            X-ray Observatory has found that
            the gas funneling into a
            supermassive black hole in the
            heart of this galaxy is a "cool"
            million degrees. This unexpected
            result adds one more quirk to the
            strange behavior previously
            observed at the center of M31.
