    "body_text": "A foreground galaxy cluster magnified a massive post-starburst galaxy at redshift 5.18 into three images, giving the team an estimated physical resolution near 70 parsecs—about seven times finer than JWST's normal blur at that distance. The galaxy's half-light radius was twice the expected size, its central stellar surface density was lower, and ionized gas sat off center. The authors say that geometry challenges a simple compact-core quenching picture for this object.",
