Upcoming Meetings
Abstract submission and registration are still open for the workshop Astrochemistry in the Broadband Era of the ngVLA and ALMA WSU held this October in Portland, Maine. Early-career researchers are especially encouraged to attend this focused meeting.

We’ll remind you of a few others on our radar, but their abstract submission has already closed. First is the astrochemistry mini-symposium at ISMS in June. There will be more than 100 astrochemistry talks at this extremely affordable, friendly conference. There is also an astrochemistry session at this summer’s meeting of the European Astronomical Society, the 38th European Conference on Surface Science, focusing on the Surface Science of Astrochemical system is to be held August 24-29 in Braga, Portugal, and there’s a dedicated astrochemistry meeting at the PacificChem 2025 conference in December.

Icarus Special Issue
There’s a special issue in the journal Icarus on “Carbon in Planetary Environments: Sources and Evolution.” The description reads:
Carbon is one of the most abundant elements, and its chemical form and evolution play a significant role in shaping planetary environments. For example, polycyclic aromatic hydrocarbons are a significant interstellar carbon reservoir, and work to characterize the chemistry and life-cycle of such material is ongoing. The interplay between carbon and oxygen in accretionary environments controls redox state and has implications for the composition of condensates. Carbon is the basis for organic chemistry that is critical for life as we know it, and may also provide valuable biosignatures for detection (remote and in situ) of extraterrestrial life. In planetary bodies, the exchange of carbon between atmospheres and interiors controls planetary climate, whereas atmospheric gases such as CO2 and CO are important for planetary habitability and CH4 is a potential biosignature gas. The linkages between inherited and evolved forms of carbon in planetary systems are coming in to sharper focus as ALMA and JWST expand our view of the cosmos, and sample return missions such as OSIRIS-REx, Hayabusa2, and Martian Moons Explorer (MMX) enable groundbreaking laboratory analysis of carbonaceous materials. At the same time, space exploration missions such as Europa Clipper, JUICE, and Dragonfly are rapidly expanding the boundaries of our knowledge, as preparations for future missions such as the Habitable Worlds Observatory continue. This Special Issue presents new research from laboratory experiments, modeling work, data analysis, and other scientific techniques on carbon in planetary systems and beyond, including astronomical sources.
Submissions will be due by Nov 30, 2025.
