June 3, 2014: Astronomers using the Hubble Space Telescope have assembled a comprehensive picture of the evolving universe — among the most colorful deep space images ever captured by the 24-year-old telescope. This study, which includes ultraviolet light, provides the missing link in star formation.
This image is a composite of separate exposures acquired by the ACS/SBC, ACS/WFC, WFC3/UVIS and WFC3/IR instruments. Several filters were used to sample various wavelengths. The color results from assigning different hues (colors) to each monochromatic (grayscale) image from the 13 different filters used by the four instruments grouped as follows:
ACS/WFC F435W(B)+F606W(V) blue
WFC3/IR F105W(Y) green
WFC3/IR F125W(J)+F140W(JH)+F160W(H) red
Hubble Ultra Deep Field Video
This video is a zoom into a small patch of sky in the constellation Fornax. This is the target area for the Hubble Ultra Deep Field, which was first observed in 2003. The low density of bright foreground stars in this region of the heavens allows astronomers to clearly view approximately 10,000 dimmer, more distant galaxies. This latest image combines separate observations taken in ultraviolet, visible, and near-infrared light. The composite yields the most colorful view of the far universe to date. It yields new clues to the birth rate of stars over the universe’s 13-billion-year history.
