This Hubble image shows a galaxy called Messier 86. The image is made up of observations from Hubble’s Advanced Camera for Surveys (ACS) in the optical part of the spectrum. Two filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

NASA’s Solar Dynamics Observatory (SDO) captured this image of the Sun with sunspots in February 2013. The picture combines images from two SDO instruments: the Helioseismic and Magnetic Imager (HMI), which takes pictures in visible light that show sunspots, and the Advanced Imaging Assembly (AIA), which took an image in the 304 angstrom wavelength showing the lower atmosphere of the Sun, which is colorized in red.

This Hubble image reveals a detailed view of part of the dwarf elliptical galaxy Messier 110. The color image was made from separate exposures taken in the visible and near-infrared regions of the spectrum with Hubble’s Wide Field Planetary Camera 2 (WFPC2). It is based on data obtained through two filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.
