Compass Image for Gravitational Wave Source in NGC 4993
GRB170817A - NGC 4993
130 million light-years (to NGC 4993)
Image is about 1.6 arcmin across, about 60,500 light-years at the distance of NGC 4993.
WFC3/UVIS F606W, WFC3/IR F110W, F160W
This image is a composite of separate exposures made by the WFC3 instrument on the Hubble Space Telescope using two different cameras and filters isolating the light of specific elements or of specific broad wavelength ranges. The color arises by assigning different hues (colors), to each monochromatic image. In this case, the colors are: blue WFC3/UVIS F606W, green WFC3/IR F110W, orange/red: WFC3/IR F160W.
