📍 The outcome
Researchers reported that dark energy flipped its sign, though the Hubble tension remained. New measurements using a neutron star merger and Dark Energy Survey data hinted at non-constant expansion.
Despite these findings, researchers stated the expansion of the universe continued to accelerate.

Answered
What is the current status of the Universe's expansion?
Researchers stated in The Japan News that the Universe's expansion is still accelerating.
What method was used to measure cosmic expansion according to Universe Today?
Astronomers used a neutron star merger to perform the measurement.
What did the Dark Energy Survey data suggest?
According to Quantum Zeitgeist, the data hints at non-constant expansion.
Where it stands
Recent astronomical measurements are examining the Universe's rate of expansion. New data from the Dark Energy Survey suggests that expansion may be non-constant and that dark energy has flipped its sign.
Additionally, astronomers have utilized a neutron star merger to measure cosmic expansion. Coverage from Phys.org, The Japan News, and Quantum Zeitgeist emphasizes that despite these new findings, the Hubble tension remains unresolved.
Technology Org reports that these measurements bring researchers closer to understanding the expansion rate, while The Japan News notes that researchers maintain the Universe's expansion is still accelerating. Future observations will likely focus on the implications of the non-constant expansion hinted at by the Dark Energy Survey and the ongoing discrepancy known as the Hubble tension.
