New research adds a wrinkle to our understanding of the origins of matter in the Milky Way

NEW RESEARCH ADDS A WRINKLE TO OUR UNDERSTANDING OF THE ORIGINS OF MATTER IN THE MILKY WAY

New findings published this week in Physical Review Letters suggest that carbon, oxygen, and hydrogen cosmic rays travel through the galaxy toward Earth in a similar way, but, surprisingly, that iron arrives at Earth differently. Learning more about how cosmic rays move through the galaxy helps address a fundamental, lingering question in astrophysics: How is … Read more
