Yes, the universe's expansion is still accelerating, researchers say

A new study confirms the universe is still expanding at an accelerating rate, countering a 2025 paper that claimed the acceleration had stopped.
Researchers relied on Type Ia supernovas—reliable "exploding star" distance markers—to measure cosmic expansion and found no evidence for the contested "age effect."
Astronomers hope upcoming observatories like the Vera Rubin telescope and the Nancy Grace Roman Space Telescope will help unravel the mystery of dark energy.
