These Hubble Space Telescope images pinpoint three distant
supernovae, which exploded and died billions of years ago.
Scientists are using these faraway light sources to estimate
if the universe was expanding at a faster rate long ago and
is now slowing down.
Images of SN 1997cj are in the left hand column; SN 1997ce,
in the middle; and SN 1997ck, on the right. All images were
taken by the Hubble telescopes Wide Field and Planetary
Camera 2. The top row of images are wider views of the
supernovae. The supernovae were discovered in April 1997 in
a ground-based survey at the Canada-France-Hawaii Telescope
on Mauna Kea, Hawaii.
