Summary
In March 2025, NASA launched the Polarimeter to Unify the Corona and Heliosphere ( PUNCH ) mission in an effort to better understand solar weather. It consists of a constellation of four microsatellites, monitoring the sun 24/7. Those satellites started taking images of coronal mass ejections (CMEs), which are explosive expulsions of materials from the sun into space, as soon as they arrived in orbit. Now, the PUNCH team has taken those images and data to show how much the mission can improve solar storm forecasts.
