Dark energy's shifting role explored through advanced supercomputer simulations

Tokyo, Japan (SPX) Oct 06, 2025
Since the early 20th century, scientists have known that the Universe is expanding at an accelerating pace. This acceleration has been attributed to dark energy, a mysterious property of spacetime that counteracts gravity. Traditionally, cosmologists have treated dark energy as constant under the Lambda Cold Dark Matter (LCDM) model, but new data are challenging this assumption.

New analyses of the South Pole-Aitken basin recast the formation of the Moon's largest impact crater and what it reveals about lunar origins. Led by University of Arizona planetary scientist Jeffrey Andrews-Hanna, the study in Nature outlines how the basin's geometry and chemistry point to a northward-moving impactor and a radioactive-rich ejecta deposit.

Scientists using the European Space Agency's Gaia telescope have discovered a vast stellar wave rippling across the Milky Way's disc, extending tens of thousands of light-years from the Sun. The finding adds to Gaia's record of uncovering the galaxy's dynamic structure, following its earlier identification of the disc's rotation, warp, and wobble.
