Carina Nebula Pillar
This image was created from HST data from proposals 12050: M. Livio, K. Noll, M. Mutchler, Z. Levay, L. Frattare, W. Januszewski, C. Christian, and T. Borders (Hubble 20th Anniversary Team, STScI); and 10241: N. Smith (University of California, Berkeley), J. Bally (University of Colorado, Boulder), N. Walborn (STScI), and J. Morse (NASA/GSFC).
F658N (H-alpha+[N II]) and F502N ([O III])
These images are composites of separate exposures made by the ACS instrument on the Hubble Space Telescope (HST). Each filter was used to sample a narrow wavelength range. The composite colors result from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are:
Yellow/gold: F658N (H-alpha+[N II])
Cyan: F502N ([O III])
