About the Image
Image Credit: NASA, ESA, and H. Bond (STScI)
Release Date: October 26, 2006
Color:

This image is a composite of many separate exposures made by the WFPC2 instrument on the Hubble Space Telescope using several different filters. Two filters were used to sample broad wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:

F606W (V) blue
V+I green
F814W (I) red

Orientation: V838 Monocerotis - September 2006
