Colour-composite of the sky field with several High-Redshift galaxies

Sky region imaged with the multi-mode FORS2 instrument on the 8.2-m VLT YEPUN telescope, in which a number of galaxies in the redshift range from 4.8 to 5.8 were discovered. They are accordingly located at a distance of about 12,600 million light-years from the Earth. This is a composite image where the blue, green and red colours correspond to the R- (central wavelength at 650 nm), the I- (about 780 nm), and the z-band filter (910 nm), respectively. The size of the sky field corresponds to about 1,000 million light-years at the distance of these galaxies. North is up and East is left.
