Compass and Scale Image for UVIS/IR/Details
HH 901 and HH 902 in the Carina Nebula
7,500 light-years (2,300 parsecs)
This image is 84 arcseconds (3.1 light-years or 0.94 parsec) wide.
This image was created from HST data from proposal 12050: M. Livio, K. Noll, M. Mutchler, Z. Levay, L. Frattare, W. Januszewski, C. Christian, and T. Borders (Hubble 20th Anniversary Team, STScI).
WFC3/UVIS (left): F673N ([S II]), F657N (H-alpha+[N II]), and F502N ([O III])
WFC3/IR (right): F126N ([Fe II]), F128N (Paschen-beta), and F164N ([Fe II])
This image is a composite of separate exposures made by the WFC3 instrument on the Hubble Space Telescope (HST). Each filter was used to sample a narrow wavelength range over a broad range of the visible colors. The composite color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are:
Red: F673N ([S II])
Green: F657N (H-alpha+[N II])
Blue: F502N ([O III])
Red: F126N ([Fe II])
Green: F128N (Paschen-beta)
Blue: F164N ([Fe II])
