The Galactic Journey of the Solar System: Astronomical, Geological, and Paleo-Climatological Perspectives
As Earth orbits the Sun, the Solar System itself revolves around the center of the Milky Way, moving through a continuously changing Galactic environment. In addition to its mean orbital […]
Astrochemistry in Planetary Science – ACS Fall 2026 National Meeting
Overview: Astrochemistry is a diverse discipline spanning virtually all divisions of chemistry and plays a vital role in planetary science. This symposium aims to foster new collaborations by highlighting current efforts […]
Where Skies Meet: Multidisciplinary Views of Planet and Exoplanet Atmospheres
The IAA-CSIC Severo Ochoa Advanced School “Where skies meet: multidisciplinary views of planet and exoplanet atmospheres” is designed for researchers interested in the study of planetary atmospheres both in the Solar System […]
Charting the Future of Stellar and Exoplanets Spectroscopy (CHASES 2026)
Looking ahead, a new generation of instruments (some of which already operational like ESPRESSO and DESI) will soon start (WEAVE, 4MOST), is planned (MOONS), or proposed — from ultra-stable high-resolution […]
77th International Astronautical Congress (IAC 2026)
The 77th International Astronautical Congress (IAC 2026) will take place in Antalya, Türkiye, from 5–9 October 2026 — marking the first time in history that the event will be hosted […]

Size Constraints For The Pre-atmospheric Parent Bodies Of Ordinary Chondrites
[astro-ph.EP] The study of S-complex near-Earth objects (NEOs), the parent bodies of ordinary chondrites, has shown that they are dominated by asteroids with LL chondrite-like compositions. This is surprising because […]

Inventories of Rich Carbon-Chain Chemistry in Prestellar and Starless Cores in the Perseus Molecular Cloud
[astro-ph.GA] Carbon-chain molecules serve as an important reservoir of reactive organic matter that will eventually be incorporated into protoplanetary disks, planets, and cometary material. Prestellar and starless cores are composed […]

Variations in the 3.3 µm Polycyclic Aromatic Hydrocarbon Feature Across Nearby Galaxies Driven by Metallicity and Radiation Field Spectrum
[astro-ph.GA] We use JWST NIRCam imaging to investigate the 3.3 μm polycyclic aromatic hydrocarbon (PAH) feature in nearby galaxies. NIRCam observations of the 3.3 μm feature are emerging as a […]
