Two close-up NICMOS views of candidate objects which may be over 12
billion light-years away. Each candidate is centered in the frame. The
reddish color may mean all of the starlight has been stretched to
infrared wavelengths by the universe's expansion. Alternative
explanations are that the objects are closer to us, but the light has
been reddened by dust scattering. A new generation of telescopes will be
needed to make follow-up observations capable of establishing true
distance.
