In 1998, astronomers using observations of distant supernovae discovered that the universe's expansion is accelerating, contrary to expectations of a slowing down, which was a groundbreaking revelation in cosmology. This finding, attributed to dark energy making up about 68% of the universe, earned the 2011 Nobel Prize in Physics and has reshaped our understanding of the cosmos.
