Webb Images Carina Nebula "Treasure Chest" as Study Revises Early Galaxy Masses
NASA's James Webb Space Telescope recorded an infrared image on Aug. 6, 2026, of a portion of the Carina Nebula, a star-forming region that also contains the Cosmic Cliffs [1]. The imaged feature, nicknamed the "Treasure Chest," is a cometary globule, described as a separate cloud of gas and dust with a dense dark head and a trailing tail [1]. Separately, astronomers using JWST reported that massive early galaxies hold far more small, faint stars than expected, which could make some of them three to four times more massive than earlier estimates [2]. The team said the result complicates explanations for how large, mature galaxies formed soon after the Big Bang and may indicate planets around low-mass stars were more common in the early universe [2].
