The universe has been expanding ever since the Big Bang almost 14 billion years ago, and astronomers believe a kind of invisible force called dark energy is making it accelerate faster.
Argonne researchers used the lab’s Aurora exascale supercomputer to perform large-scale simulations of the universe, ...
The resulting geomagnetic storm is expected to produce a moderate (G1-class) geomagnetic storm, which could cause weak ... dark skies, away from sources of light pollution like cities. Aurora ...
