Sensing suns

Red supergiants are extremely bright but difficult to study due to their complex upper atmospheres. Astronomers have now developed a new technique to estimate their surface temperatures using iron absorption lines. By combining these temperatures with accurate distance measurements, researchers found consistent results with theory.
