Explanation:
Light from a star that exploded over 10 billion light-years away
is revealed in the panel at the lower right,
a cosmic
snapshot of the most
distant supernova.
The ancient stellar detonation
was detected
by digitally subtracting before and
after images of a faint, yellowish, elliptical galaxy
included in the Hubble Space Telescope Deep
Field image illustrated at the top and left.
Remarkable in itself as the
farthest known supernova, its measured
brightness provides astounding
evidence for
a strange universe -
one which eventually
defies gravity and expands at an
accelerating rate.
The unseen force driving
this
expansion is dubbed
dark energy
and discovering the fundamental
nature
of dark energy has been called
the challenge of this millennium.
