Explanation:
Galaxies like colorful pieces of candy fill the
Hubble Ultra Deep Field 2014.
The dimmest galaxies are more than 10 billion times fainter than
stars visible to the unaided eye and represent the
Universe in
the extreme past, a few 100 million years after the
Big Bang.
The image itself
was made with the significant addition
of ultraviolet data to the Hubble Ultra Deep Field,
an update of Hubble's
famous
most distant gaze toward the southern constellation of Fornax.
It now covers the entire range of wavelengths available to
Hubble's cameras, from ultraviolet through visible to near-infrared.
Ultraviolet data adds the crucial capability of studying
star formation in the
Hubble Ultra
Deep Field galaxies between 5 and 10 billion light-years distant.
