Titan’s Organic World
Titan, Saturn’s largest moon, possesses a dense N2–CH4 atmosphere driving complex organic chemistry. The interplay among photochemistry, aerosol formation, organic cloud condensation, and surface deposition makes Titan a natural laboratory […]
Asteroid Sample Return Missions Are Critical For Understanding Our Solar System
Studying asteroids addresses a number of unknowns in planetary science. Investigating them makes use of asteroidal meteorites, remote observations and space-based missions.
Constraints On The Crystallinity Of Water Ice In Planet-forming Disks From Infrared Scattered-Light Spectra
The crystallinity of water ice not only records the thermal history experienced by an astronomical body, but also affects the composition of forming planets by controlling the trapping of volatile […]
Spinning Out Of Focus: The Challenge Of Rotational Line Broadening In Exoplanet Reflection Spectroscopy
Detecting light reflected off the dayside of an exoplanet in high-resolution spectroscopic data has proved to be a notoriously difficult endeavour. Despite several attempts, the faint signal has yet to […]
🚀 NASA Request for Information (RFI): Private Sector Activities in Astrobiology, Planetary Protection, and Space Biology Released
NASA’s Science Mission Directorate (SMD) has released a new Request for Information (RFI) entitled, Private Sector Activities in Astrobiology, Planetary Protection, and Space Biology, seeking expressions of interest from U.S. […]
The Role of Formation Location in Shaping Sulfur-, Nitrogen-, and Carbon-Bearing Species in Super-Earth and Sub-Neptune Atmospheres
Atmospheric compositions of sub-Neptunes and super-Earths are often interpreted as tracers of formation location relative to volatile ice lines.
Coupled Photochemical-Climate Modeling of Plausible Tenuous Outgassed Atmospheres on the TRAPPIST-1 Planets
Available JWST observations TRAPPIST-1 system have suggested that several of the planets are likely airless, or possess a very tenuous atmosphere.
Observation Of Spontaneous N-bearing PAH Formation Using Ion Trap: A New Formation Pathway In The Interstellar Medium
Nitrogen-bearing polycyclic aromatic hydrocarbons (N-PAHs) are key precursors to complex organic molecules in both the interstellar medium and the nitrogen-rich planetary atmospheres.
Astrochemistry: Surrounded by Stardust: Iron-60 Discovery In Antarctic Ice Reveals: Local Interstellar Cloud Leaves Its Mark
Our Solar System is currently passing through the Local Interstellar Cloud, a region of highly diluted gas and dust between the stars.
