It's because dark matter doesn't interact with light. The difference is subtle, but important. Regular matter can be dark because it absorbs light. It's why, for example, we can see the shadow of molecular clouds against the scattered stars of the Milky Way. This is possible because light and matter have a way to connect. https://phys.org/news/2024-09-dark-slight-interaction-regular.html Astronomy Thu, 26 Sep 2024 15:10:05 EDT news646582201 NASA's Artemis science instrument gets tested in moon-like sandbox On Sept. 9 and 10, scientists and engineers tested NASA's LEMS (Lunar Environment Monitoring Station) instrument suite in a "sandbox" of simulated moon regolith at the Florida Space Institute's Exolith Lab at the University of Central Florida in Orlando. https://phys.org/news/2024-09-nasa-artemis-science-instrument-moon.html Space Exploration Thu, 26 Sep 2024 15:01:13 EDT news646581669 New hazard maps may predict rust disease in loblolly pine trees New models developed by University of Georgia researchers may help guide the fight against rust disease, according to a new study.
