Planet Formation

Formation of super-Earths proven limited near metal-poor stars

An international team of astronomers has utilized NASA's James Webb Space Telescope to investigate the disk of gas and dust surrounding a young, low-mass star called ISO-ChaI 147. Their findings, depicted in this artist's impression, show the most diverse and abundant collection of carbon-containing molecules ever observed in a planet-forming disk around a star.
