Scientists are now using this dataset to probe dark energy, the force driving the universe’s accelerated expansion. Early results hint that dark energy may evolve over time, a possibility that could challenge current cosmological models and reshape fundamental physics. With the mission extended through 2028, researchers aim to refine our understanding of cosmic structure, history, and the ultimate fate of the universe by the end of the decade. Thank you for listening to Bedtime Astronomy — your guide to the cosmos. New episodes on space exploration, NASA missions & the latest astronomy breakthroughs.
