The study's results rebut research published last year that concluded that this cosmic expansion is no longer speeding up – a finding that had challenged the basic understanding of the universe.
The universe is still accelerating," said astrophysicist Brodie Popovic of the University of Southampton in England, one of the leaders of the study published this month in the journal Monthly Notices of the Royal Astronomical Society.
The study's findings, by a team that included two Nobel Prize recipients, were guided by observations in two different datasets of a type of stellar explosion called a Type Ia supernova in order to calculate vast cosmic distances. These supernovas cause the destruction of an object called a white dwarf, the dense remnant of a low – to intermediate – mass star at the end of its lifecycle.
