UrduA new Webb study of two protostars, so young that they have not yet formed planets, has found a variety of molecules ranging from relatively simple ones like methane to complex compounds like acetic acid (familiar to cooks as an ingredient in vinegar). These molecules constitute key ingredients for worlds that might one day host life.

Carbon atoms coming together in space
Lab-based studies reveal how carbon atoms diffuse on the surface of interstellar ice grains to form complex organic compounds, crucial to reveal the chemical complexity in the universe.
VLA Finds Megastorms on Saturn Disrupt Gas Giant’s Deep Atmosphere in Surprising Ways
A study of rare megastorms on Saturn using data from the National Science Foundation’s Karl G. Jansky Very Large Array has revealed disruptions in the distribution of ammonia gas in the planet’s deep atmosphere. The findings raise questions about just how different gas giants can be from each other, and challenge scientists’ understanding of how megastorms may form on planets other than Earth. The results of the study appear in Science Advances.
A Surprise Chemical Find by ALMA May Help Detect and Confirm Protoplanets
Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) to study the protoplanetary disk around a young star have discovered the most compelling chemical evidence to date of the formation of protoplanets.
Gemini North Detects Multiple Rock-Forming Elements in the Atmosphere of a Scorching Exoplanet
Astronomers using the Gemini North telescope, one half of the International Gemini Observatory operated by NSF’s NOIRLab, have detected multiple rock-forming elements in the atmosphere of a Jupiter-sized exoplanet, WASP-76b. The planet is so perilously close to its host star that rock-forming elements — such as magnesium, calcium, and nickel — become vaporized and dispersed throughout its scorching atmosphere. This intriguing chemical profile provides new insights into the formation of planetary systems, including our own.
Gemini Norte detecta múltiples elementos que forman rocas en la atmósfera de un exoplaneta sumido en el infierno
Utilizando el telescopio de Gemini Norte, la mitad boreal del Observatorio Internacional Gemini, que opera NOIRLab de NSF y AURA, un equipo de astrónomos detectó diversos elementos formadores de rocas en la atmósfera de un exoplaneta del tamaño de Júpiter llamado WASP-76b. El planeta está tan peligrosamente cerca de su estrella que los elementos formadores de rocas, como el magnesio, calcio y níquel, se evaporan y se dispersan por toda su abrasadora atmósfera. Este intrigante perfil químico provee nuevos conocimientos sobre la formación de sistemas planetarios, incluido el nuestro.
ALMA Reveals Carbon-Rich, Organic Birth Environments of Planets
An international collaboration of scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) has completed the most extensive chemical composition mapping of the protoplanetary disks around five nearby young stars at high resolution, producing images that capture the molecular composition associated with planetary births, and a roadmap for future studies of the makeup of planet- and comet-forming regions.
