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 […]
Webb Observes Carbon Oxides On Uranus’ Moon Ariel That Hint At A Hidden Ocean
The surface of Uranus’ moon Ariel is coated with a significant amount of carbon dioxide ice, especially on its “trailing hemisphere” that always faces away from the moon’s direction of […]
Constraining Time Variations in Enceladus’ Water-Vapor Plume With Near-Infrared Spectra from Cassini-VIMS
Water vapor produces a series of diagnostic emission lines in the near infrared between 2.60 and 2.75 microns. The Visual and Infrared Mapping Spectrometer (VIMS) onboard the Cassini spacecraft detected […]
Enceladus: Astrobiology Revisited
Astrobiology research seeks to understand how life begins and evolves, and to determine whether life exist elsewhere in the universe. The discovery of diverse ocean worlds has significantly expanded the […]
Water Plumes On Enceladus Caused By Strike–Slip Motion
Over the course of its elliptical orbit, the moon Enceladus is squeezed unevenly by Saturn’s gravitational pull and deforms from a spherical shape into a football shape and back again. […]
The Surface Of Enceladus Shields Buried Organics
The Saturnian moon Enceladus presents a unique opportunity in our Solar System to search for evidence of life, given its habitable ocean and plume that deposits organic-bearing ocean material onto […]
JWST Molecular Mapping And Characterization Of Enceladus’ Water Plume Feeding Its Torus
Enceladus is a prime target in the search for life in our solar system, having an active plume likely connected to a large liquid water subsurface ocean.
Webb Space Telescope Maps Surprisingly Large Plume Jetting From Saturn’s Moon Enceladus
A water vapour plume from Saturn’s moon Enceladus spanning more than 9600 kilometres — long enough to stretch across the Eurasian continent from Ireland to Japan — has been detected […]
Could Life Be Found On Saturn’s Moon Enceladus?
What can we learn about NASA Cassini spacecraft’s discovery of tiny particles from the icy ocean of Saturn’s moon Enceladus? What is causing these nanometer-sized silica grains to rise up […]
