A Search For Water Vapor Plumes On Europa By spatially Resolved Spectroscopic Observation Using Subaru/IRCS
We present near-infrared high-dispersion spectroscopic observations of Europa using the Infrared Camera and Spectrograph (IRCS) onboard the Subaru Telescope, seeking direct evidence of water plumes on Europa and exploring spatial […]

Water In Protoplanetary Disks With JWST-MIRI
This work aims at providing some general tools for the analysis of water spectra as observed in protoplanetary disks with JWST-MIRI. We use 25 high-quality spectra from the JDISC Survey […]

Hubble Helps Solve The Mystery Of Mars’ Escaping Water
Scientists have discovered that the escape rates of hydrogen and “heavy hydrogen,” called deuterium, change rapidly when Mars is close to the Sun. This upended the classical picture that scientists […]

Varying Water Activity and Momentum Transfer on Comet 67P/Churyumov-Gerasimenko From its non-gravitational Forces and Torques
We investigate the ability of a simultaneous fitting of comet 67P/Churyumov-Gerasimenko’s non-gravitational forces, torques and total water-outgassing rate, as observed by Rosetta, to constrain complex thermophysical models of cometary material.

Planets Contain More Water Than Previously Thought
Most of a planet’s water is generally not found on the surface, but is hidden deep inside. This affects the potential habitability of distant worlds, as model calculations by researchers […]
