This image of the irregular dwarf galaxy Sextans B, taken by the Nicholas U. Mayall 4-m Telescope, features red-colored star-forming regions near the galaxy’s center; surrounding the galaxy are several bright stars that are located much closer to us in our Milky Way Galaxy, identified by the crisscross patterns created by light interacting with the structure of the telescope, as well as numerous fuzzy-looking background galaxies that appear small because they are much farther away than Sextans B.

This Hubble image shows AG Carinae, a luminous blue variable star some 20,000 light-years away in the constellation of Carinae. The color image was made from separate exposures taken in the visible and ultraviolet regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3) instrument. Four filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.
