Fomalhaut; Fomalhaut b
25 light-years (8 parsecs)
This image is roughly 462 astronomical units (60 arcseconds) wide.
The science team includes: P. Kalas (University of California, Berkeley and SETI Institute, Mountain View, Calif.), J. Graham (University of California, Berkeley and University of Toronto), M. Fitzgerald (UCLA), and M. Clampin (NASA/GSFC).
This image is a composite of many separate exposures made by the STIS instrument on the Hubble Space Telescope. This image was originally black and white and recorded only overall brightness. These brightness values were translated into a range of reddish hues. Such color "maps" can be useful in helping to distinguish subtly varying brightness in an image.
