NASA's James Webb Space Telescope has confirmed that the universe is expanding faster than previously expected. This new data, collected over the past two years, supports earlier findings from the Hubble Space Telescope. Researchers found that the distances between stars and galaxies are increasing more rapidly now than in the early universe. This aligns with earlier studies and suggests that the phenomenon known as Hubble Tension may be linked to dark energy. The Webb telescope's observations provide clearer data than Hubble's, indicating a need to possibly revise current models of the universe. Scientists plan to gather more data to further investigate the causes of this accelerated expansion.
