Compass and Scale Image of Jet in Carina (WFC3 UVIS and IR)
Jet in Carina
7,500 light-years (2,300 parsecs)
This image is 3 arcminutes (6.6 light-years or 2.0 parsecs) wide.
The Hubble images were created from data from proposal 11501: K. Noll (STScI), C. Proffitt (STScI/CSC), D. Leckrone and M. Niedner (NASA/GSFC), and M. Livio and Z. Levay (STScI).
WFC3/UVIS (top): F502N ([O III]), F656N (H-alpha), and F673N ([S II])
WFC3/IR (bottom): F126N ([Fe II]) and F164N ([Fe II])
The image is a composite of separate exposures made by the WFC3 instrument on the Hubble Space Telescope. Five filters were used to sample narrow wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:
WFC3/UVIS image (top):
Red: F673N ([S II])
Green: F656N (H-alpha)
Blue: F502N ([O III])
WFC3/IR image (bottom):
Cyan: F126N ([Fe II])
Orange: F164N ([Fe II])
