            "description": "This image captures a variety of cells around blood vessels and shows how astrocytes, which regulate multiple aspects of brain health, respond to radiation. Astrocytes gather to form a pattern similar to a scar (green) and express a protein that controls the permeability of blood vessels (red). Cell nuclei appear in blue. Studying how space radiation affects cells and organ models, including the brain, enables scientists to better understand the risks to astronaut health and develop countermeasures to protect crew on long-duration space journeys. \r\n\r\nFor more information visit\r\n[https://science.nasa.gov/multimedia/march-2025/](https://science.nasa.gov/multimedia/march-2025/)",
