Instrument: ACS
Exposure Date(s): November/December 2003

Image Credit: NASA, ESA, and the Hubble Heritage (STScI/AURA)-ESA/Hubble Collaboration
Release Date: November 29, 2007
Color:

This image is a composite of many separate exposures made by the ACS instrument on the Hubble Space Telescope. Three filters were used to sample broad wavelength ranges, while one filter was used to sample a narrow wavelength band. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:

F435W (B) blue
F555W (V) green
F656N (Halpha + [N II]) and F814 (I) red
Orientation/Scale: Spiral Galaxy M74
