Hubble Space Telescope Gazes at Swirling Spiral Galaxy

This Hubble image shows NGC 3285B, a barred spiral galaxy some 137 million light-years away in the constellation of Hydra. The color image was made from separate exposures taken in the ultraviolet and infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3). It is based on data obtained through seven filters. Image credit: NASA / ESA / Hubble / R.J. Foley, UC Santa Cruz.

This Hubble image shows NGC 1786, a globular cluster located about 163,000 light-years away in the constellation of Dorado. The color image was made from separate exposures taken in the ultraviolet, visible and near-infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3). Three filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.
