This Hubble image shows NGC 2210, a globular cluster located 163,000 light-years away in the constellation of Dorado. Also known as ESO 57-71 or LW 423, the cluster was first discovered on January 31, 1835 by the English astronomer John Herschel. The color image is made up of observations from Hubble’s Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3) and in the ultraviolet, near-infrared, and optical parts of the spectrum. It is based on data obtained through three filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.

This Hubble image shows the globular cluster NGC 1850, which is located in the Large Magellanic Cloud, over 160,000 light-years from Earth. For this image, five filters were used with the camera to gather data. Two of the filters were at near-ultraviolet wavelengths, two more at visible light wavelengths, and the final one was in the near-infrared. The data gathered through the two ultraviolet filters is violet and blue. The data from the two visible light filters is green and orange. The color red denotes near-infrared data. The image follows chromatic order, which means the shortest wavelength in the image is blue while the longest wavelength is red. Chromatic order allows us to visualize wavelengths of light beyond our eye’s sensitivity in a way that is familiar to us. Image credit: NASA / ESA / N. Bastian, Donostia International Physics Center / Gladys Kober, NASA & Catholic University of America.
