The ‘Teacup’ quasar is causing an ongoing storm. The ‘handle’ is a ring of X-ray (blue) and optical (red and green) light surrounding a giant bubble, shown in the Chandra and Hubble data. This handle-shaped feature, which is located about 30,000 light-years from the galaxy’s central supermassive black hole, was likely formed by one or more eruptions powered by the black hole.

This Hubble image shows the elliptical galaxy Messier 49. The image was made from separate exposures taken in the visible and infrared regions of the spectrum with Hubble’s Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3). Four filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.
