Compass and Scale Image for M60
Messier 60, M60, and M60-UCD1
M60 and M60-UCD1 are roughly 54 million light-years (16 megaparsecs) distant.
Data for this science result comes from the HST proposal: 12369 G. Fabbiano (Harvard-Smithsonian Center for Astrophysics), T. Fragos and V. Kalogera (Northwestern University), D.-W. Kim and A. Zezas (Harvard-Smithsonian Center for Astrophysics), J. Gallagher III (University of Wisconsin, Madison) , A. King (University of Leicester), J. Strader (Harvard University), and J.

ACS/WFC: F475W (B) and F850LP (z);
WFPC2: F555W (V) and F814W (I)
The images are composites of separate exposures made by the ACS/WFC and WFPC2 instruments on the Hubble Space Telescope. Four filters were used to sample broad and narrow wavelength ranges for the UVIS image. The colors result from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:
Blue: ACS/WFC F475W (B) + WFPC2 F555W (V)
Green: F475W (B) + F555W (V) + F850LP (z) + F814W (I)
Red: ACS/WFC F850LP (z) + WFPC2 F814W (I)
